Symptoms such as a cough every morning, a little phlegm to clear or breathlessness after taking a flight of stairs may seem minor at first. Most people associate these symptoms with factors such as smoking, age, pollution or a passing cold. While the presumption can be true in some cases, these symptoms can also be early signs of chronic obstructive pulmonary disease (COPD) - a long-term, progressive lung condition that develops slowly over years. By the time it starts affecting daily activities, significant damage may already be done, and much of it cannot be reversed. World COPD Day is observed every year to improve awareness about the condition and promote early diagnosis. In line with the observation, this article covers the early symptoms of COPD, how it is managed, and when to see a doctor.

About World COPD Day

World COPD Day was first observed in 2002 by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), in collaboration with healthcare professionals and patient groups. Since then, it has grown into a global awareness initiative, with activities organised across several countries. It is observed on the third Wednesday of November every year.

The day aims to raise awareness about chronic obstructive pulmonary disease (COPD), its risk factors and the impact it has on everyday life. The day encourages people to recognise early symptoms, understand the importance of lung health and seek medical advice when breathing problems persist. It also highlights the need for better awareness, timely diagnosis and access to appropriate care for people living with COPD.

Theme for World COPD Day 2026

The theme for World COPD Day 2026 is 'Early Diagnosis and Management for a Better Life'. Announced by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), the theme highlights the importance of recognising COPD early and starting appropriate care to manage symptoms, reduce the risk of complications and support a better quality of life.

What is COPD and How Does it Affect the Lungs?

Chronic obstructive pulmonary disease (COPD) is a long-term lung condition that makes it difficult to breathe. It develops when the airways become inflamed or narrowed, or when the tiny air sacs in the lungs become damaged. As airflow becomes restricted, breathing requires more effort, and everyday activities can gradually become tiring.

COPD commonly involves two conditions, which may occur separately or together:

• Chronic Bronchitis: The bronchial tubes, which carry air to and from the lungs, become inflamed and produce excess mucus. This often leads to a persistent cough and regular phlegm production.

• Emphysema: The walls of the alveoli (tiny air sacs responsible for exchanging oxygen and carbon dioxide) become damaged. These air sacs lose their elasticity, causing air to become trapped in the lungs and making it harder to breathe out.

Over time, these changes can cause persistent airflow obstruction and affect the lungs' ability to function efficiently. COPD generally progresses gradually, although the rate of progression varies from person to person. While existing lung damage cannot be reversed, appropriate treatment can help manage symptoms and slow further deterioration.

Smoking is a major risk factor, but it isn't the only one. Other factors that can contribute to COPD include:

• Long-term exposure to indoor smoke from cooking with solid fuels.

• Outdoor air pollution.

• Occupational exposure to dust, fumes and chemicals.

• Passive smoking or prolonged exposure to second-hand smoke.

• Genetic conditions such as alpha-1 antitrypsin deficiency.

COPD Symptoms That Should Not be Ignored

One of the challenges with COPD is that its early symptoms can be easy to overlook. A persistent cough may be dismissed as a smoker's cough, while breathlessness might be blamed on ageing or a lack of physical activity. Since these changes often develop gradually, people may adjust their routines without realising that their breathing has changed.

Some common symptoms to look out for include:

• Persistent Cough: A cough that continues for weeks or months may be one of the early signs of COPD. It can be particularly noticeable in the morning, although some people experience coughing throughout the day.

• Excess Phlegm: Regularly coughing up mucus or frequently clearing the throat can indicate increased mucus production in the airways.

• Breathlessness: Shortness of breath may initially occur during activities such as walking uphill, climbing stairs or carrying groceries. As the condition progresses, even less strenuous activities can become difficult.

• Wheezing: Narrowed airways can cause a whistling sound while breathing, particularly when breathing out. It may become more noticeable during physical activity or respiratory infections.

• Chest Tightness: Some people experience pressure or tightness in the chest, which can make taking a deep breath uncomfortable.

• Frequent Chest Infections: Repeated respiratory infections, including episodes of bronchitis, may occur in people with COPD. These infections can also worsen existing respiratory symptoms.

• Fatigue: Restricted airflow can make breathing more physically demanding. This additional effort, along with disrupted sleep and reduced physical activity, may contribute to persistent tiredness.

There is also a difference between ongoing COPD symptoms and a sudden worsening of the condition. A noticeable increase in breathlessness, coughing or mucus production over a short period may indicate a COPD exacerbation, commonly called a flare-up.

Severe or sudden breathing difficulty, bluish lips or confusion require immediate medical attention. Coughing up blood or experiencing chest pain also warrants prompt evaluation.

How is COPD Diagnosed?

A persistent cough or breathlessness alone cannot confirm COPD. Since several respiratory conditions can cause similar symptoms, doctors consider the person's medical history, exposure to risk factors and lung function before reaching a diagnosis.

The evaluation may involve the following:

• Medical History: The doctor asks about the duration and frequency of symptoms, smoking habits, exposure to air pollution, occupational hazards and previous respiratory infections.

• Physical Examination: The lungs are examined for wheezing, unusual breathing sounds and signs of respiratory difficulty. However, a normal physical examination does not rule out COPD.

• Spirometry: This is the main test used to confirm COPD. The person takes a deep breath and blows forcefully into a mouthpiece connected to a machine. It measures how much air can be exhaled and how quickly it leaves the lungs.

The test is generally performed before and after using a bronchodilator, a medicine that helps open the airways. A post-bronchodilator FEV1/FVC ratio below 0.70 supports a COPD diagnosis when considered alongside the clinical findings.

• Chest Imaging: A chest X-ray or CT scan may help identify lung changes, assess possible emphysema or rule out other conditions. Imaging alone cannot confirm COPD.

• Additional Tests: Depending on the symptoms, doctors may recommend blood tests, oxygen level assessment or other lung function investigations. Testing for alpha-1 antitrypsin deficiency may also be considered in appropriate cases.

Once COPD is confirmed, the doctor assesses the severity of airflow obstruction, the impact of symptoms on daily activities and the history of flare-ups. This information helps guide the management plan.

How Can COPD Progression Be Managed?

COPD causes lasting changes to the lungs, and there is currently no treatment that can reverse all the damage. However, appropriate treatment and lifestyle changes can help manage symptoms, reduce the risk of flare-ups and support everyday functioning.

The approach depends on the severity of the condition, existing symptoms and overall health. Common management measures include:

• Smoking Cessation: Stopping smoking is one of the most important steps in managing COPD. It helps reduce continued exposure to substances that damage the lungs. People who find it difficult to quit can discuss counselling, behavioural support and suitable cessation medicines with a healthcare professional.

• Prescribed Medication: Bronchodilators help relax the muscles around the airways, making it easier to breathe. Depending on the symptoms and history of exacerbations, doctors may prescribe short-acting or long-acting inhalers. Inhaled corticosteroids may be recommended for selected patients when clinically appropriate.

• Pulmonary Rehabilitation: This structured programme combines supervised exercise, breathing techniques, education and guidance on managing breathlessness. It helps people improve their exercise capacity and maintain greater independence in daily activities.
• Vaccination: Respiratory infections can trigger COPD flare-ups. Recommended vaccinations, including those for influenza, pneumococcal disease and COVID-19, can help reduce the risk of certain infections.

• Avoiding Lung Irritants: Reducing exposure to tobacco smoke, indoor cooking smoke, dust, chemical fumes and outdoor air pollution can help limit further irritation of the airways.

• Regular Physical Activity: Walking, gentle exercises and activities recommended through pulmonary rehabilitation can help maintain muscle strength and physical endurance. The level of activity should be guided by individual symptoms and medical advice.

• Nutritional Support: Maintaining a balanced diet is important because breathing difficulties can sometimes make eating tiring. Some people with COPD may also experience reduced appetite or unintentional weight loss. A doctor or dietitian can suggest suitable dietary changes.

• Regular Monitoring: Follow-up appointments help assess changes in symptoms, review treatment and monitor lung function where indicated. They also provide an opportunity to check inhaler technique and discuss any recent flare-ups.

Recognising a COPD flare-up is equally important. A sudden increase in breathlessness, a change in the amount or colour of mucus, or worsening cough may indicate an exacerbation. Following an action plan discussed with the treating doctor can help determine when additional medical care is needed. Severe breathing difficulty requires emergency attention.

Do Your Part This World COPD Day

World COPD Day is an opportunity for everyone to contribute to better awareness of lung health. Here are a few ways to get involved:

• Attend Awareness Events: Participate in online webinars, educational sessions and local activities organised by respiratory health organisations. These events offer opportunities to learn about COPD, hear different perspectives and understand the challenges faced by people living with the condition.

• Wear Orange: Wear orange on 18 November to show support for COPD awareness. You can also encourage friends, family and colleagues to join in and use the colour as a conversation starter about lung health.

• Join Social Media Campaigns: Take part in GOLD's 2026 Big Baton Pass, a 24-hour online relay that brings together people living with COPD, families, healthcare professionals and researchers. Participants can record a 30-second selfie video explaining why COPD matters to them, end with "I am passing the baton on" and upload it to the campaign. Share it using the hashtags #COPDBatonPass and #WorldCOPDDay.

• Support Someone Living With COPD: Check in on friends or family members who have COPD. Offer practical help with everyday activities, accompany them to appointments if needed and be considerate of their breathing difficulties.

• Support Smoking Cessation: Support smoke-free homes and workplaces. If someone wants to quit smoking, help them find appropriate cessation resources and encourage them to seek professional guidance.

• Support Access to Respiratory Care: Encourage initiatives that improve access to spirometry, pulmonary rehabilitation and respiratory healthcare, particularly in communities where these services may be limited.

Final Words

World COPD Day is a good opportunity to pay a little more attention to respiratory health, both for ourselves and the people around us. Take the day to learn about COPD, share reliable information about its early symptoms and encourage those who smoke or have persistent respiratory complaints to take them seriously. And if you or a loved one experience any concerning respiratory symptoms discussed above consult a pulmonologist can assess the symptoms, recommend spirometry when appropriate and help determine whether they could be related to COPD or another respiratory condition.

According to the International Diabetes Federation (IDF), the number of adults living with diabetes worldwide is projected to rise from 589 million in 2024 to 853 million by 2050. This growing number makes diabetes prevention increasingly important, particularly when it comes to type 2 diabetes, where healthier lifestyle choices can significantly reduce the risk of developing the condition. So, this World Diabetes Day, let’s look at what causes type 2 diabetes and what lifestyle choices help reduce the risk. 

About World Diabetes Day

World Diabetes Day was established in 1991 by the International Diabetes Federation (IDF) and the World Health Organization (WHO) in response to growing concerns about the rising incidence of diabetes worldwide. In 2006, the United Nations officially recognised 14 November as World Diabetes Day, making it a global observance.

The day provides an opportunity to bring attention to the challenges associated with diabetes and encourage collective efforts towards better awareness, prevention, early diagnosis and care. It also highlights the importance of making diabetes information more accessible and supporting people living with the condition.

Theme for World Diabetes Day 2026

The theme for World Diabetes Day 2026-27 is “Early Action on Diabetes”. The campaign highlights the importance of recognising risk factors, identifying diabetes early and ensuring timely access to care. It also emphasises the need to reduce the risk of type 2 diabetes through preventive measures and healthier environments.

Common Risk Factors for Type 2 Diabetes

Type 2 diabetes develops when the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood glucose levels. Several factors can influence this process. Some of the common risk factors include:

• Family History: Having a parent or sibling with type 2 diabetes increases the likelihood of developing the condition. Genetic factors can influence how the body produces and responds to insulin, making some individuals more susceptible.

• Overweight and Abdominal Obesity: Excess body fat, particularly around the abdomen, is associated with increased insulin resistance. This can make it harder for the body to use insulin effectively and maintain healthy blood glucose levels.

• Increasing Age: The risk of type 2 diabetes generally increases with age, particularly after 35 years. However, the condition can also develop in younger adults, adolescents and children.

• Prediabetes: People with prediabetes have blood glucose levels that are higher than normal but not high enough to meet the diagnostic criteria for diabetes. Without appropriate intervention, they have an increased likelihood of progressing to type 2 diabetes.

• Polycystic Ovary Syndrome (PCOS): PCOS is associated with insulin resistance and an increased risk of type 2 diabetes. Women with PCOS may benefit from periodic blood glucose screening, particularly when other metabolic risk factors are present.

• History of Gestational Diabetes: Women who develop diabetes during pregnancy have a higher risk of developing type 2 diabetes later in life. Regular screening after pregnancy can help identify changes in blood glucose levels early.

Having one or more of these risk factors does not mean that a person will necessarily develop type 2 diabetes..

Lifestyle Changes That Can Help Reduce the Risk

Some risk factors, such as age and family history, cannot be changed. However, everyday lifestyle choices can influence metabolic health and help reduce the risk of developing type 2 diabetes. Consistent changes to daily routines can improve insulin sensitivity, support healthy blood glucose levels and contribute to better overall health.

Here are some lifestyle changes that can help:

• Move After Meals: A short walk after lunch or dinner can help muscles use glucose and reduce post-meal blood glucose spikes. Even a 10–15-minute walk can be a useful starting point.

• Break Up Sitting Time: If work involves sitting for several hours, take short movement breaks throughout the day. Walking around for a few minutes, taking the stairs or standing between tasks can help reduce prolonged sedentary time.

• Rethink Meal Portions: Pay attention to how much is eaten, particularly when meals include rice, roti or other carbohydrate-rich foods. Pairing these with vegetables, pulses and protein sources can help create more balanced meals.

• Choose Fibre-Rich Foods: Replace some refined grains with whole grains, include vegetables and pulses regularly, and choose whole fruits instead of fruit juices. Dietary fibre supports better blood glucose regulation and satiety.

• Avoid Sugary Drinks: Soft drinks, packaged juices and sweetened beverages can add considerable amounts of sugar without providing much satiety. Water and unsweetened drinks are better everyday choices.

• Keep a Consistent Sleep Schedule: Try to maintain regular sleeping and waking times instead of frequently shifting sleep schedules. Adequate sleep supports metabolic health and helps regulate appetite.

• Find Manageable Ways to Unwind: Persistent stress can affect sleep, eating patterns and blood glucose regulation. Activities such as walking, breathing exercises or meditation can help manage stress.

These changes are not a substitute for medical advice, particularly for people with prediabetes or other existing risk factors.

Symptoms That Warrant Medical Attention

One of the challenges with type 2 diabetes is that it can develop gradually, sometimes without causing noticeable symptoms in the early stages. Blood glucose levels may remain elevated for years before a person realises something is wrong. This is why waiting for symptoms before getting tested may delay diagnosis.

As the condition progresses, some people may experience the following symptoms:

• Frequent Urination: When blood glucose levels become too high, the kidneys work harder to remove excess glucose through urine. This can increase urine production and cause more frequent trips to the toilet, including at night.

• Increased Thirst: Frequent urination can cause the body to lose more water than usual, leading to dehydration and persistent thirst. A person may feel thirsty even after drinking water.

• Unexplained Weight Loss: Some people may lose weight without changing their diet or physical activity levels. This can happen when the body cannot use glucose effectively and starts breaking down fat and muscle for energy.

• Persistent Fatigue: When glucose cannot enter the body's cells effectively, they may not receive the energy they need. This can contribute to ongoing tiredness, weakness and a lack of energy even after adequate rest.

• Blurred Vision: High blood glucose levels can cause changes in the fluid balance of the eye, temporarily affecting the ability to focus clearly. Vision may become blurry or fluctuate as blood glucose levels change.

• Slow-Healing Wounds: Persistently high blood glucose can affect circulation, blood vessels and the body's ability to heal. As a result, cuts, sores and other wounds may take longer to recover.

• Tingling or Numbness: Prolonged exposure to high blood glucose can damage nerves over time, particularly those in the feet and hands. This may cause tingling, burning sensations, pain or numbness.

These symptoms do not necessarily indicate diabetes, as they can also occur with other health conditions. However, persistent or unexplained symptoms warrant medical assessment and appropriate blood glucose testing.

Final Words

Reducing the risk of type 2 diabetes does not always require major lifestyle changes. However, lifestyle changes are only one part of prevention, and people with risk factors such as family history, PCOS or prediabetes should also pay attention to regular blood glucose screening. This World Diabetes Day, take the opportunity to understand your risk, make informed choices and seek medical guidance from an endocrinologist when needed.

Pneumonia claims millions of lives worldwide every year, affecting adults as well as children - particularly those under five. Many of these deaths can be prevented through timely medical attention and following preventive measures. That's why World Pneumonia Day is observed every year with the aim of raising awareness about pneumonia and reducing preventable pneumonia related deaths. In line with the day's objective, this article covers the common symptoms of pneumonia, who is more vulnerable to the infection and what steps can help lower the risk.

About World Pneumonia Day

World Pneumonia Day is observed every year on 12 November to raise awareness about pneumonia, its impact on public health and the measures that can help prevent and treat the infection. First observed in 2009, the day was established by the Global Coalition Against Child Pneumonia, bringing together healthcare organisations, medical professionals and public health advocates to address the burden of pneumonia, particularly among young children.

World Pneumonia Day serves as an opportunity to address these challenges and encourage action at both individual and community levels. It draws attention to several important aspects of pneumonia control:

• Raising Awareness: Educating people about pneumonia, its causes, symptoms and potential complications.

• Promoting Prevention: Encouraging vaccination, better nutrition, improved hygiene and measures to reduce exposure to respiratory infections.

• Supporting Early Diagnosis: Helping people recognise warning signs and seek medical attention without unnecessary delays.

• Improving Healthcare Access: Highlighting the importance of making essential medicines, medical oxygen and appropriate treatment accessible to those who need them.

Theme for World Pneumonia Day 2026

The theme for World Pneumonia Day 2026 is "A New Era of Pneumonia Control." Announced by the Every Breath Counts Coalition, the theme recognises the progress made in pneumonia prevention, diagnosis and treatment, while highlighting the need to make these advances accessible to more people.

Over the years, developments in vaccines, diagnostic tools and treatment options have created more opportunities to prevent severe pneumonia and manage infections effectively. However, the availability of these interventions does not automatically mean that everyone can benefit from them. Gaps in vaccination coverage, limited diagnostic facilities and unequal access to essential treatment continue to affect pneumonia outcomes.

The 2026 theme draws attention to the following areas of progress and continued action:

• Improved Vaccines: Vaccines against pneumococcal disease, influenza, Haemophilus influenzae type b (Hib), measles and other infections can help prevent illnesses that may lead to pneumonia.

• Better Diagnostics: Tools such as pulse oximeters help healthcare professionals assess blood oxygen levels and identify people who may need additional respiratory support.

• Effective Treatments: Appropriate antibiotics for bacterial pneumonia, supportive care and access to medical oxygen can help manage the infection and its complications.

• Wider Healthcare Access: Making preventive services, diagnostic facilities and essential treatments available, particularly in underserved communities, remains important.

Early Signs and Symptoms of Pneumonia to Watch For

Pneumonia develops when an infection causes inflammation in the lungs, particularly in the tiny air sacs called alveoli. These air sacs may fill with fluid or pus, making it harder for the lungs to transfer oxygen into the bloodstream. This can cause a range of symptoms that could be mild or sever:

• Persistent Cough: A cough that may produce mucus, which can sometimes appear yellow, green or blood-stained. A dry cough may also occur.

• Fever and Chills: An increase in body temperature, often accompanied by sweating, shivering and a general feeling of being unwell.

• Shortness of Breath: Difficulty breathing or feeling breathless, even during routine activities. Breathing may also become faster than usual.

• Chest Pain: Sharp or aching chest pain that becomes more noticeable while taking deep breaths or coughing.

• Fatigue and Weakness: Unusual tiredness, low energy and difficulty carrying out everyday activities.

• Loss of Appetite: Reduced appetite, nausea or vomiting may occur in some cases.

• Confusion: Older adults may experience confusion, disorientation or changes in alertness, sometimes without developing a noticeable fever.

Pneumonia can present differently in infants and young children, who may not be able to communicate what they are experiencing. Parents and caregivers should watch for:

• Rapid or difficult breathing.

• Chest indrawing, where the lower chest moves inward during inhalation.

• Grunting or unusual sounds while breathing.

• Difficulty feeding or drinking.

• Unusual sleepiness, reduced activity or irritability.

• Fever or unusually low body temperature.

People at a Higher Risk of Pneumonia

Although pneumonia can affect anyone, certain age groups and people with specific health conditions are more vulnerable to developing the infection or experiencing severe complications. These include:

• Young Children: Children below five years, particularly infants, have developing immune systems that make them more susceptible to respiratory infections. Premature birth, malnutrition and incomplete vaccination can further increase their risk.

• Older Adults: People aged 65 years and above are more vulnerable because immune function tends to decline with age. Existing health conditions and reduced respiratory function can also increase the likelihood of complications.

• People With Chronic Conditions: Individuals with diabetes, heart disease, chronic obstructive pulmonary disease (COPD), asthma and other long-term conditions may face a higher risk of pneumonia. These conditions can affect the body's ability to respond to infections or cope with respiratory complications.

• Immunocompromised Individuals: People with weakened immune systems due to certain illnesses, cancer treatments, organ transplants or immunosuppressive medicines may have greater difficulty fighting infections.

• Smokers: Tobacco smoke damages the airways and interferes with the lungs' natural defence mechanisms, making it easier for harmful microorganisms to cause infections.

Simple Ways to Reduce the Risk of Pneumonia

While no single measure can prevent every case, a combination of preventive steps can lower the risk of certain infections and reduce the likelihood of severe illness.

Here are some practical ways to help protect against pneumonia:

Vaccination is one of the most effective ways to prevent infections that can lead to pneumonia. Several vaccines offer protection against specific bacterial and viral infections associated with the condition.

These include:

• Pneumococcal Vaccine: Protects against infections caused by Streptococcus pneumoniae, a major bacterial cause of pneumonia. It is particularly important for young children, older adults and certain people with underlying health conditions.

• Influenza Vaccine: Helps prevent seasonal flu, which can sometimes lead to viral pneumonia or increase the risk of secondary bacterial pneumonia.

• Hib Vaccine: Protects against Haemophilus influenzae type b, which can cause pneumonia and other serious infections, particularly in young children.

• COVID-19 Vaccine: Helps reduce the risk of severe COVID-19, which can cause pneumonia.

• Other Routine Vaccines: Immunisation against measles and pertussis (whooping cough) can also help prevent infections associated with pneumonia.

Vaccination recommendations vary according to age, medical history and local immunisation guidelines. A healthcare professional can help determine which vaccines are appropriate for different individuals. 

Respiratory infections can spread through respiratory droplets and contact with contaminated hands or surfaces. Regular handwashing helps reduce the transmission of germs that can cause these infections.

Some simple hygiene practices include:

• Washing hands with soap and water, particularly before eating and after coughing, sneezing or blowing the nose.

• Using an alcohol-based hand sanitiser when soap and water are unavailable.

• Avoiding touching the eyes, nose and mouth with unwashed hands.

• Cleaning frequently touched surfaces, especially when someone at home is unwell.

Smoking damages the tiny hair-like structures called cilia that help clear mucus and harmful particles from the respiratory tract. It also affects the lungs' ability to defend themselves against infections.

Avoiding tobacco products and exposure to second-hand smoke can help protect respiratory health. Keeping homes and other indoor spaces smoke-free is particularly important for children and older adults.

Poor air quality can irritate the respiratory tract and weaken its natural protective barriers. Exposure to household smoke from cooking fuels, tobacco smoke and outdoor air pollution can contribute to respiratory health problems.

Some ways to reduce exposure include:

• Improving ventilation in homes and workplaces.

• Using cleaner cooking fuels and reducing exposure to cooking smoke.

• Avoiding indoor burning of waste, incense and other materials that produce smoke.

• Checking local air quality levels and limiting outdoor activities when pollution levels are high.

• Using suitable air filtration where possible, particularly in poorly ventilated indoor environments.

Reducing air pollution exposure is especially important for people with existing respiratory conditions.

Good nutrition supports normal immune function and helps the body respond to infections. Malnutrition, particularly among young children, is an important risk factor for severe pneumonia.

A balanced diet should include adequate protein, fruits, vegetables, whole grains and other nutrient-rich foods. For infants, exclusive breastfeeding during the first six months of life is recommended by the WHO, followed by appropriate complementary feeding alongside continued breastfeeding.

Children and adults with nutritional deficiencies may require individual dietary assessment and guidance.

Conditions such as diabetes, asthma, COPD and heart disease can increase the risk of severe respiratory infections. Keeping these conditions under control can help reduce complications if an infection develops.

This includes following prescribed treatment plans, attending recommended follow-up appointments and discussing any new or worsening respiratory symptoms with a healthcare professional.

Simple habits can help reduce the spread of respiratory infections within households and communities.

• Cover the mouth and nose with a tissue or the elbow while coughing or sneezing.

• Dispose of used tissues appropriately and wash hands afterwards.

• Avoid close contact with people who have active respiratory infections.

• Stay home when unwell, where possible, to reduce the spread of infection.

• Maintain good ventilation in shared indoor spaces.

These measures are particularly useful for protecting people who may be more vulnerable to respiratory infections.

Help Spread Awareness this World Pneumonia Day

World Pneumonia Day is an opportunity to help more people understand the risks associated with pneumonia and the steps that can reduce its impact. Here are a few ways to contribute to pneumonia awareness:

• Share Reliable Information: Spread awareness about pneumonia symptoms, risk factors and preventive measures through conversations and social media.

• Encourage Vaccination: Help family members understand the importance of recommended vaccinations, particularly for young children and older adults.

• Educate Caregivers: Share information about childhood pneumonia symptoms, including rapid breathing, chest indrawing and difficulty feeding.

• Promote Clean Air: Encourage smoke-free homes, better ventilation and reduced exposure to household air pollution.

• Support Community Initiatives: Participate in health awareness programmes and initiatives that improve access to preventive healthcare.

Final Words

World Pneumonia Day reminds us that reducing the burden of pneumonia requires greater awareness and action, particularly when it comes to prevention. Pneumonia prevention comes down to being proactive about respiratory health and not overlooking symptoms that could indicate an infection. If symptoms such as a persistent cough, fever or breathlessness develop, timely medical assessment can help identify the cause and guide treatment. Consult a pulmonologist if you experience these symptoms or have concerns about your respiratory health.

Diwali brings the warmth of glowing diyas, the sparkle of festive lights and the excitement of fireworks lighting up the night. But with it also comes the smoke, leaving behind polluted air that often leads to various respiratory symptoms or flare-ups in people with asthma or other respiratory conditions. To help recognise the respiratory risks of Diwali air pollution and understand how to reduce its impact, this article covers the signs to look out for and the precautions you can take.

Why Air Quality Worsens Around Diwali

Diwali often coincides with a period when air quality is already deteriorating in many parts of India. Firecracker emissions add to the existing pollution, while seasonal weather conditions can prevent pollutants from dispersing easily. The result is a build-up of harmful particles and gases in the air, particularly in urban areas.

Several factors contribute to the rise in air pollution around Diwali:

• Firecracker Emissions: Fireworks release fine particulate matter, smoke and gases into the atmosphere. Some firecrackers also release metals and other chemical compounds that contribute to air pollution. The concentration of pollutants can rise sharply when fireworks are set off in large numbers over a short period.
• Weather Conditions: Diwali falls during the transition to winter in much of northern India. Low wind speeds and temperature inversions can limit the movement of pollutants, allowing them to remain closer to the ground for longer. Cooler air and changing weather patterns can make it harder for pollution to disperse.
• Existing Pollution: Vehicle exhaust, industrial emissions, construction dust and other everyday sources already contribute to poor air quality. Firecracker smoke adds to this existing pollution rather than acting as the only source.

These factors can combine to increase exposure to air pollution during and after Diwali. Fine particulate matter is a particular concern because smaller particles can travel deep into the respiratory system when inhaled.

How Air Pollution Affects Respiratory Health

Air pollution can affect the respiratory system in different ways. Here are some of the possible respiratory effects:

Smoke and airborne pollutants can irritate the lining of the nose, throat and airways. This may cause a scratchy throat, dryness, sneezing or a burning sensation in the nose. The eyes may also become irritated, particularly when someone is close to firecracker smoke.

These symptoms may improve after exposure ends, although continued exposure to polluted air can prolong the irritation.

The respiratory system has natural defence mechanisms that help remove inhaled particles. When smoke and pollutants irritate the airways, they can trigger coughing as the body attempts to clear the irritants.

Some people may also develop wheezing, a whistling sound produced when air moves through narrowed airways. Wheezing can be particularly concerning in people with asthma or other conditions that affect airflow.

Fine particulate matter and other pollutants can contribute to airway inflammation and make breathing uncomfortable. People may notice breathlessness during physical activity or experience a feeling of tightness in the chest.

Those with existing respiratory conditions may be more sensitive to these effects. New or worsening breathlessness should not be dismissed as a normal consequence of the festive season.

Air pollution is a recognised trigger for asthma symptoms. Exposure to firecracker smoke and fine particles can irritate already sensitive airways, potentially leading to coughing, wheezing, chest tightness and shortness of breath.

In some cases, symptoms may become severe enough to require urgent medical attention. People with asthma should follow their prescribed treatment plan and take precautions to minimise exposure during periods of poor air quality.

Chronic obstructive pulmonary disease (COPD) is a long-term lung condition that causes airflow obstruction and breathing difficulties. Exposure to polluted air can aggravate symptoms in people living with COPD.

This may include increased breathlessness, more frequent coughing or a change in the amount or appearance of mucus. A sudden worsening of these symptoms may indicate a COPD exacerbation and should be assessed by a healthcare professional.

Fine particles such as PM2.5 are small enough to penetrate deep into the lungs. Exposure can trigger inflammation in the respiratory tract and may affect the lungs' normal defence mechanisms.

The effects depend on the level and duration of exposure, as well as individual susceptibility. Repeated exposure to air pollution is associated with a greater risk of respiratory problems, although the impact of a particular Diwali exposure varies from person to person.

Who is More Vulnerable to Air Pollution?

Air pollution can affect anyone, including people who do not have a diagnosed respiratory condition. However, certain groups are more susceptible to its effects because their lungs are still developing, their respiratory function may be compromised, or they have existing health conditions. The following groups may need to take extra precautions during periods of high pollution:

Children's lungs are still developing, and they breathe more air relative to their body weight than adults. Exposure to polluted air can irritate their airways, trigger coughing and worsen asthma symptoms. Keeping children away from firecracker smoke and limiting outdoor activities when air quality is poor can help reduce their exposure.

Age-related changes in lung function and the presence of chronic health conditions can make older adults more susceptible to air pollution. Those with existing heart or lung diseases may experience worsening symptoms during periods of poor air quality.

People with asthma have sensitive airways that can become inflamed and narrow when exposed to certain triggers. Firecracker smoke and fine particulate matter may provoke symptoms, including wheezing, coughing and chest tightness. Even brief exposure can trigger symptoms in some individuals.

People living with COPD may already experience reduced airflow and difficulty breathing. Additional exposure to air pollution can worsen these symptoms and increase the likelihood of an exacerbation, particularly when pollution levels are high.

Individuals with other chronic respiratory conditions or cardiovascular diseases may also be more vulnerable to the effects of polluted air. Those who have previously experienced breathing difficulties during periods of poor air quality should take particular care to limit exposure.

People who work outdoors, including traffic personnel, delivery workers and street vendors, may spend several hours exposed to polluted air. Longer exposure can increase the amount of pollution they inhale, particularly when protective measures are limited

Tips to Reduce Exposure to Air Pollution

It may not be possible to avoid air pollution entirely during Diwali, especially in areas where pollution levels are already high. However, a few practical measures can help reduce exposure and limit its potential effects on respiratory health: 

Check the Air Quality Index (AQI) through reliable sources, such as the Central Pollution Control Board's monitoring services. The AQI provides information about the level of air pollution and its potential health implications.

When air quality is poor, consider the following precautions:

• Limit outdoor activities, particularly strenuous exercise.
• Reschedule walks, runs and outdoor workouts for periods when air quality is better.
• Avoid areas with visible smoke or heavy firecracker activity.
• Keep children and people with existing respiratory conditions indoors when pollution levels are high.

Remember that pollution levels can vary significantly across neighbourhoods and throughout the day. Check local readings rather than relying only on general reports for a city.

Staying indoors can help reduce exposure to outdoor pollution, but fine particles can still enter homes through open windows, doors and other gaps.

These measures can help limit indoor exposure:

• Keep windows and external doors closed during periods of heavy outdoor smoke.
• Use a portable air purifier with a high-efficiency particulate air (HEPA) filter, if available.
• Avoid adding indoor pollutants through smoking, incense sticks, candles or other sources of smoke.
• Follow the manufacturer's instructions for maintaining air purifiers and replacing filters.

Closing windows throughout the day may affect ventilation, so air the home when outdoor pollution levels are lower. An air purifier can reduce airborne particles in a suitable room, but it cannot eliminate every pollutant.

If going outdoors is unavoidable during periods of high pollution, a well-fitting N95 or equivalent particulate respirator can help reduce inhalation of fine particles.

For better protection:

• Choose a respirator that fits snugly over the nose and mouth.
• Ensure there are no significant gaps around the edges.
• Replace it if it becomes damaged, dirty or difficult to breathe through.
• Remember that cloth masks and loose-fitting surgical masks offer limited protection against fine particulate matter.

Particulate respirators do not protect against every gas or chemical vapour in firecracker smoke. They should be used alongside other measures to reduce exposure, rather than as a substitute for avoiding heavily polluted areas.

One of the most practical ways to reduce exposure is to avoid being close to firecrackers when they are set off. Smoke concentrations can be particularly high near the source.

Consider these precautions:

• Avoid standing close to fireworks or areas where firecrackers are being burst.
• Keep children, older adults and people with respiratory conditions away from smoke.
• Avoid lighting firecrackers in enclosed or poorly ventilated spaces.
• Consider celebrating with diyas, lights and other activities that do not generate firecracker smoke.

If smoke begins to accumulate nearby, move away from the affected area rather than waiting for it to clear.

People with asthma, COPD or other chronic respiratory conditions should continue their prescribed treatment and follow their clinician's advice during periods of poor air quality.

Some useful precautions include:

• Keep prescribed inhalers and other essential medicines accessible.
• Follow the existing asthma or COPD action plan, if one has been provided.
• Avoid changing medication doses or starting additional medicines without medical advice.

Staying hydrated may help ease throat dryness, but drinking water does not remove inhaled pollutants from the lungs. The priority should remain reducing exposure and managing symptoms appropriately.

When Should You Seek Medical Attention?

Mild throat irritation or an occasional cough after exposure to smoke may settle once the exposure stops. However, persistent symptoms or new breathing difficulties should not be ignored, particularly in people with existing respiratory conditions.

Medical attention may be necessary in the following situations:

• Persistent Cough: A cough that continues, worsens or interferes with sleep and daily activities warrants medical evaluation.
• Wheezing: New wheezing or a noticeable increase in wheezing may indicate airway irritation or worsening of an existing respiratory condition.
• Worsening Breathlessness: Seek medical advice if breathing becomes more difficult than usual, particularly during routine activities.
• Asthma Flare-Ups: If asthma symptoms become more frequent or the prescribed rescue inhaler provides less relief than usual, follow the asthma action plan and seek medical advice promptly.
• Changes In COPD Symptoms: Increased breathlessness, worsening cough or changes in mucus production may indicate an exacerbation that needs assessment.

Seek emergency medical care if there is severe difficulty breathing, bluish lips or skin, confusion, fainting or severe chest pain. Do not wait for these symptoms to improve on their own.

Final Word

Diwali should be a time to celebrate, not struggle to breathe. If breathing difficulties, persistent coughing or other respiratory concerns arise during or after the festivities, don't dismiss them as temporary effects of pollution. Consult a pulmonologist to understand what may be causing the symptoms and get appropriate medical advice.

Liver cancer can develop without causing any noticeable symptoms, making it easy to overlook in its early stages. A person may feel perfectly well until symptoms such as yellowing of the skin and eyes begin to appear. By then, the disease may be more advanced, which can make treatment more challenging. This is why knowing what increases the risk of liver cancer and which warning signs to look out for matters. In this article, we explore both to help you understand what to watch for.

What is Liver Cancer?

Liver cancer develops when abnormal cells in the liver grow uncontrollably and form a tumour. It can begin in the liver itself or spread to the liver from another part of the body. These are known as primary and secondary liver cancer, respectively, and the distinction matters because the treatment approach depends on where the cancer originated.

The most common types of liver cancer include:

• Hepatocellular Carcinoma (HCC): The most common type of primary liver cancer, HCC begins in hepatocytes, the main cells of the liver.

• Intrahepatic Cholangiocarcinoma: This cancer develops in the small bile ducts within the liver, which carry bile to aid digestion.

• Secondary Liver Cancer: This occurs when cancer that began in another organ, such as the colon, breast or pancreas, spreads to the liver. It is treated according to the original cancer and its characteristics.

Liver cancer can affect people with existing liver disease, although it can also develop in those without a known history of liver problems. 

What are the Risk Factors for Liver Cancer?

Liver cancer can develop for several reasons, and some of the most significant risk factors are linked to long-term liver damage or chronic infection. Having one or more of these factors does not mean a person will necessarily develop cancer, but it can increase their risk. The main factors associated with liver cancer include: 

• Chronic Hepatitis B and C: Long-term infection with hepatitis B or hepatitis C viruses can cause persistent inflammation and damage to liver cells. Over time, this can increase the risk of liver cancer. Hepatitis B can also increase the risk in people who have not developed cirrhosis.

• Cirrhosis: This condition occurs when healthy liver tissue is replaced by scar tissue, often due to chronic liver disease. Cirrhosis is one of the strongest risk factors for hepatocellular carcinoma, regardless of its underlying cause.

• Fatty Liver Disease: Metabolic dysfunction-associated steatohepatitis (MASH), a form of fatty liver disease involving inflammation and liver cell injury, can progress to cirrhosis and increase the risk of liver cancer. In some cases, cancer develops even without cirrhosis.

• Heavy Alcohol Consumption: Long-term heavy drinking can damage liver cells and lead to cirrhosis, raising the risk of cancer. Alcohol use may further increase the risk in people with chronic hepatitis infections.

• Smoking: Tobacco use is associated with an increased risk of liver cancer, alongside its many other health effects.

• Other Factors: Obesity, type 2 diabetes, certain inherited conditions and exposure to aflatoxins can also contribute to the risk. Aflatoxins are toxic substances produced by certain moulds that can contaminate improperly stored grains, nuts and other foods.

What are the Early Warning Signs of Liver Cancer?

One of the challenges with liver cancer is that its early stages may not cause noticeable symptoms. As the disease progresses, changes may become more apparent, although these symptoms can also occur with other medical conditions. Potential warning signs include: 

• Unexplained Weight Loss: Losing weight without making changes to diet or physical activity can be a warning sign that warrants medical assessment.

• Upper Abdominal Pain: Persistent discomfort or pain in the upper right side of the abdomen, near the liver, may occur. Some people may also experience pain near the right shoulder blade or back.

• Jaundice: Yellowing of the skin and the whites of the eyes can occur when bilirubin builds up in the boy. Dark urine and pale stools may accompany it.

• Abdominal Swelling: The abdomen may become enlarged due to fluid accumulation, known as ascites, or an enlarged liver.

• Loss of Appetite: A reduced appetite, nausea or feeling unusually full after eating a small amount of food may develop.

• Persistent Fatigue: Unusual tiredness, weakness or a general decline in energy can occur as the disease affects overall health.

• Easy Bruising or Bleeding: Some people may notice that they bruise or bleed more easily than usual.

These symptoms do not automatically indicate liver cancer, and it is important not to draw conclusions based on them alone. However, persistent or unexplained changes should be assessed by a doctor.

How is Liver Cancer Diagnosed?

Diagnosis involves assessing the liver, identifying suspicious growths and determining whether cancer is present. The investigations may include:

The doctor reviews symptoms, existing liver conditions, family history and other risk factors. A physical examination may help identify abdominal swelling, an enlarged liver or other signs that require further investigation.

Blood tests help assess liver function and identify abnormalities that may need further investigation. An alpha-fetoprotein (AFP) test may also be used, as elevated levels can occur in some people with liver cancer. However, AFP alone cannot confirm or rule out the disease.

Ultrasound, CT scans and MRI scans help identify suspicious growths, assess their size and location, and determine whether the cancer may have spread. In people with certain risk factors, characteristic findings on multiphasic CT or MRI may be sufficient to diagnose hepatocellular carcinoma without a biopsy.

A liver biopsy involves collecting a small tissue sample for examination under a microscope. Doctors may recommend it when imaging results are inconclusive or when tissue confirmation is needed to establish the type of cancer.

What are the Treatment Options for Liver Cancer?

Liver cancer treatment depends on several factors, including the type and stage of the cancer, whether it has spread, the liver's remaining function and the patient's overall health. The main treatment options include: 

A partial hepatectomy involves removing the part of the liver containing the tumour. It may be suitable when the cancer is localised and enough healthy liver tissue remains to maintain normal function.

A liver transplant replaces the diseased liver with a donor liver. It may be an option for selected patients whose cancer meets established transplant criteria and whose overall health supports the procedure.

Ablation uses techniques such as radiofrequency or microwave energy to destroy cancer cells. Doctors may recommend it for certain smaller tumours, particularly when surgery is unsuitable or as part of a broader treatment plan.

Embolisation treatments target the tumour through its blood supply. Transarterial chemoembolisation (TACE) delivers chemotherapy and restricts blood flow to the tumour, while radioembolisation uses radioactive particles to target cancer cells. These procedures may be considered for selected patients whose cancer is confined mainly to the liver.

Targeted therapy uses medicines that act on specific molecules or pathways involved in cancer growth. These treatments may be recommended for advanced liver cancer, depending on the tumour's characteristics and the patient's overall health.

Immunotherapy helps the immune system recognise and attack cancer cells. Certain immunotherapy medicines, sometimes combined with targeted drugs, are used to treat advanced or unresectable hepatocellular carcinoma.

Radiation therapy uses carefully directed radiation to damage cancer cells. It may help control liver tumours in selected cases, depending on the tumour's location, the surrounding healthy tissue and the patient's liver function.

The treating team considers the potential benefits, risks and goals of care before recommending a treatment plan. 

Can Liver Cancer be Prevented?

Liver cancer cannot always be prevented, but addressing certain risk factors can reduce the likelihood of developing the disease. Some practical measures include: 

• Get Vaccinated: Hepatitis B vaccination helps prevent infection with a virus that can cause chronic liver disease and increase liver cancer risk.

• Treat Hepatitis Infections: Testing and appropriate treatment for hepatitis B and C can help reduce liver damage and the associated cancer risk. People with chronic hepatitis B may still require long-term monitoring even when receiving treatment.

• Limit Alcohol Consumption: Avoiding alcohol or reducing consumption can help prevent alcohol-related liver damage. People with existing liver disease should discuss alcohol use with their doctor.

• Maintain a Healthy Weight: Regular physical activity, a balanced diet and appropriate weight management can help reduce the risk of metabolic conditions associated with liver disease.

• Avoid Smoking: Not smoking helps reduce exposure to a known liver cancer risk factor and supports overall health.

• Follow Medical Monitoring: People with cirrhosis and certain other high-risk conditions may need regular liver cancer surveillance, commonly with ultrasound every six months, with or without an AFP blood test depending on clinical guidance. A doctor can determine the appropriate schedule based on individual risk.

Final Words

Taking care of your liver starts with knowing what puts it at risk, so if you have a condition that raises your chances of liver cancer, ask your doctor about regular monitoring, even if you feel well. The same applies if you notice a symptom that sticks around or has no clear cause, because getting it checked early, rather than waiting for it to get worse, gives you the best chance of acting while treatment options are still open.

During a brain stroke, millions of brain cells die with every passing minute. Because of this, emergency medicine places immense emphasis on the first 60 minutes following the onset of symptoms, also referred to as the "Golden Hour." This crucial window represents the most critical period for intervention, as rapid treatment is essential to prevent permanent damage. In this article, we’ll explore what actually happens during those vital 60 minutes, how to spot a stroke fast, and what it takes to ensure the best possible outcome.

What Golden Hour Means in Stroke Care

The golden hour refers to the first hour after stroke symptoms begin, when getting medical attention as quickly as possible is especially important. During a stroke, the brain may lose its normal blood supply due to a blocked artery, or brain tissue may be damaged by bleeding. In either case, delays in treatment can increase the risk of lasting brain damage.

However, the golden hour is not a strict deadline for treatment. Some treatments are available within specific time windows, and certain patients may benefit from treatment several hours after symptoms begin. The appropriate treatment depends on the type of stroke, the time of symptom onset, brain imaging results and the patient's overall condition.

This is why recognising the symptoms and reaching a hospital equipped to manage stroke emergencies as quickly as possible is so important. 

What are the Warning Signs of a Stroke?

Stroke symptoms often appear suddenly, and recognising them early can help someone get the medical attention they need. The signs can vary depending on which part of the brain is affected, so it is important to look out for any sudden change in movement, speech, vision or coordination.

One simple way to remember the main warning signs is the BE FAST method:

• Balance: Sudden loss of balance, dizziness or difficulty walking.

• Eyes: Sudden vision changes, including blurred or double vision or loss of vision.

• Face Drooping: One side of the face may droop or feel numb. The person's smile may appear uneven.

• Arm Weakness: One arm may suddenly feel weak or numb, or drift downwards when both arms are raised.

• Speech Difficulty: Speech may become slurred, unclear or difficult to understand. The person may also struggle to find the right words.

• Time to Act: If any of these signs appear, call emergency services immediately. Note when the symptoms began, but do not delay seeking help.

Other warning signs can include difficulty walking, confusion, numbness or a severe headache with no known cause.

What Should You Do During the Golden Hour?

A suspected stroke requires immediate medical attention, even if the symptoms seem mild or disappear after a few minutes. Acting quickly can help medical teams assess the situation and determine the most appropriate treatment.

Here are the steps to follow if someone shows signs of a stroke:

• Call Emergency Services: Contact emergency medical services immediately. Explain the symptoms and follow the operator's instructions. Avoid waiting to see if the person feels better.

• Note the Time: Record when the symptoms first appeared. If the person wakes up with symptoms, note when they were last known to be well. This information helps doctors determine which treatments may be appropriate.

• Keep them Comfortable: Help the person rest in a safe position while waiting for emergency services. Follow the emergency operator's instructions, especially if the person becomes drowsy or loses consciousness.

• Follow Medical Instructions: Follow the emergency operator's guidance on what to do while help is on the way. Do not give food, drink or medication unless a medical professional advises it.

If possible, use an ambulance rather than arranging transport yourself. Emergency teams can begin assessment and coordinate care while taking the person to hospital.

How is a Stroke Treated?

Stroke treatment depends on the type of stroke, the area of the brain affected, the severity of symptoms and the time elapsed since symptoms began. The primary goals are to restore blood flow to the brain where possible, control bleeding when a blood vessel has ruptured, limit further brain damage and reduce the risk of complications. Treatment begins with an urgent medical assessment and brain imaging to determine the cause of the stroke.

An ischaemic stroke occurs when a blood clot blocks the blood supply to part of the brain. Treatment focuses on restoring blood flow and preventing further clots.

Thrombolysis: Eligible patients may receive intravenous thrombolytic medicines, such as alteplase or tenecteplase, which help dissolve the clot blocking blood flow. These medicines are most effective when administered promptly, generally within 4.5 hours of symptom onset. In selected cases, advanced imaging may help doctors determine whether treatment could still be beneficial beyond this period.

Mechanical thrombectomy: When a large blood vessel supplying the brain is blocked, doctors may recommend a procedure called mechanical thrombectomy. A specialist guides a catheter through a blood vessel, usually from the groin or wrist, to reach and remove the clot. The procedure is generally performed as soon as possible and may be an option for selected patients up to 24 hours after they were last known to be well, depending on brain imaging and other clinical factors.

Medication to prevent further clots: Depending on the cause of the stroke, doctors may prescribe antiplatelet medicines or anticoagulants to reduce the risk of another clot. The choice and timing of medication depend on the patient's condition and the stroke's underlying cause.

A haemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding in or around the brain. Treatment aims to control the bleeding, manage pressure inside the skull and prevent further damage.

Blood pressure management: Carefully controlled blood pressure treatment may help reduce the risk of continued bleeding. The target and pace of treatment depend on the patient's condition and the nature of the haemorrhage.

Medicines and reversal treatments: If a patient is taking anticoagulants, doctors may use specific reversal treatments where appropriate to reduce their effect and help control bleeding. Other medicines may be required to manage complications, depending on the circumstances.

Neurosurgery or other procedures: Some patients may need surgery or a minimally invasive procedure to relieve pressure on the brain, remove a collection of blood or treat the underlying cause of bleeding. For example, a ruptured aneurysm may require a procedure to seal it and prevent further bleeding. The recommended approach depends on the location and severity of the haemorrhage.

Recovery may begin once the patient's medical condition is stable. Rehabilitation helps address difficulties with movement, speech, swallowing, memory and everyday activities. Depending on individual needs, the rehabilitation programme may include physiotherapy, occupational therapy and speech and language therapy.

The timing and intensity of rehabilitation are tailored to the patient's condition and progress. Some people recover many of their abilities, while others need ongoing support to manage lasting effects of a stroke.

Long-term treatment aims to reduce the risk of another stroke. Depending on the underlying cause, this may include medicines to manage blood pressure, cholesterol or blood clots, along with appropriate treatment for conditions such as atrial fibrillation. Lifestyle measures, including stopping smoking, maintaining a balanced diet, staying physically active as advised and managing diabetes, can also form part of the prevention plan.

How Can the Risk of a Stroke be Reduced?

Although not every stroke can be prevented, managing certain health conditions and making healthy lifestyle choices can help lower the risk. 

Some practical steps that can help reduce stroke risk include:

• Control Blood Pressure: High blood pressure is a major risk factor for stroke. Regular monitoring, a balanced diet, physical activity and prescribed medication can help keep it under control.

• Manage Diabetes: High blood glucose can damage blood vessels over time. Following the recommended treatment plan and monitoring glucose levels can help reduce this risk.

• Monitor Cholesterol: High levels of LDL cholesterol can contribute to plaque build-up in the arteries. Dietary changes and medication, when prescribed, can help manage cholesterol levels.

• Quit Smoking: Smoking damages blood vessels and increases the risk of blood clots. Quitting can help improve cardiovascular health.

• Stay Physically Active: Regular exercise supports heart health, helps manage blood pressure and can contribute to maintaining a healthy weight.

• Follow a Balanced Diet: Include vegetables, fruits, whole grains and other nutrient-rich foods while limiting excess salt and saturated fats.

• Manage Heart Conditions: Conditions such as atrial fibrillation can increase the risk of blood clots that may cause a stroke. Appropriate medical evaluation and treatment can help reduce this risk.

Final Words

A stroke can change a person's life in a matter of minutes, which is why recognising the emergency and acting quickly are so important. If someone suddenly develops symptoms that could indicate a stroke, do not wait for them to improve or assume it is too late to seek help. Call emergency services immediately, even if the symptoms seem mild or more than an hour has passed. 

Most people associate a heart attack with sudden chest pain, as it is one of its most common signs. A heart attack can, however, also cause other symptoms that are easier to overlook or mistake for something less serious. Recognising these signs and seeking emergency medical care can help limit damage to the heart and reduce the risk of serious complications. This article explores the causes of a heart attack, the warning signs to look out for and the treatment options available.

What is a Heart Attack?

A heart attack, medically known as a myocardial infarction, occurs when blood flow to part of the heart muscle is severely reduced or blocked. The heart needs a continuous supply of oxygen-rich blood to function. When this supply is interrupted, the affected heart muscle begins to sustain damage.

Most heart attacks occur because of coronary artery disease, a condition in which fatty deposits called plaques build up inside the coronary arteries. If a plaque ruptures, a blood clot can form and block blood flow to the heart muscle. Without prompt treatment, the affected tissue may suffer permanent damage.

A heart attack is a medical emergency that requires immediate attention. The extent of heart muscle damage depends partly on how long blood flow remains restricted and how quickly treatment begins.

What Causes a Heart Attack?

A heart attack most commonly occurs when blood flow through one of the coronary arteries becomes blocked. However, other conditions can also restrict the blood supply to the heart. The main causes include:

• Coronary Artery Disease: Fatty deposits gradually accumulate inside the coronary arteries, narrowing the space available for blood to flow. This can restrict the supply of oxygen to the heart muscle.

• Plaque Rupture: The outer layer of a plaque can break, triggering the formation of a blood clot. If the clot blocks a coronary artery, it can cause a heart attack.

• Coronary Artery Spasm: A sudden tightening of a coronary artery can temporarily or severely restrict blood flow to the heart. In some cases, this can trigger a heart attack.

• Spontaneous Coronary Artery Dissection (SCAD): This uncommon condition occurs when a tear develops in the wall of a coronary artery, disrupting blood flow. It can cause a heart attack even in people without typical cardiovascular risk factors.

• Reduced Oxygen Supply: In some circumstances, a severe imbalance between the oxygen supplied to the heart and its needs can cause a heart attack, particularly when another illness or condition places significant strain on the body.

Who is at Risk of a Heart Attack?

A heart attack can affect people of different ages, although the likelihood generally increases with age. Certain medical conditions, lifestyle habits and inherited factors can increase the risk by contributing to coronary artery disease or placing additional strain on the cardiovascular system.

Some important risk factors include:

• High Blood Pressure: Persistently elevated blood pressure can damage artery walls and contribute to the development of coronary artery disease.

• High Cholesterol: High levels of LDL cholesterol can promote the formation of fatty deposits inside the arteries, increasing the risk of blockages.

• Diabetes: Elevated blood glucose levels can damage blood vessels and increase the likelihood of developing cardiovascular disease.

• Smoking: Tobacco use damages blood vessels, promotes plaque formation and increases the likelihood of blood clot formation.

• Unhealthy Lifestyle: Physical inactivity, a diet high in saturated and trans fats, and excess body weight can contribute to cardiovascular risk.

• Age and Family History: The risk generally increases with age. A family history of premature cardiovascular disease can also indicate a higher inherited risk.

• Existing Heart Disease: People with established coronary artery disease or a previous heart attack have a higher risk of further cardiac events.

Some risk factors can be modified through lifestyle changes and medical treatment, while others, such as age and family history, cannot be changed. 

What are the Warning Signs of a Heart Attack?

Heart attack symptoms can vary in intensity and presentation. Some people experience sudden, severe chest pain, while others develop discomfort or breathlessness that initially seems mild. Symptoms may also begin gradually or come and go.

Heart attack warning signs can include:

• Chest Discomfort: Pressure, tightness, squeezing, heaviness or pain in the centre of the chest. The discomfort may last several minutes or disappear and return.

• Pain in Other Areas: Discomfort may spread to one or both arms, the shoulders, back, neck, jaw or upper abdomen.

• Shortness of Breath: Difficulty breathing may occur with chest discomfort or on its own.

• Cold Sweats: Sudden sweating without an obvious cause can accompany a heart attack.

• Nausea or Indigestion: Some people experience nausea, vomiting or discomfort that resembles indigestion.

• Dizziness or Light-headedness: A feeling of faintness or sudden weakness may occur during a cardiac event.

• Unusual Fatigue: Some people, particularly women, may experience unexplained tiredness or weakness, sometimes before the heart attack itself.

Chest pain remains a common heart attack symptom in both men and women. However, symptoms do not always follow the same pattern, and the absence of severe chest pain does not rule out a heart attack.

A heart attack can also occur without obvious symptoms, which is sometimes described as a silent heart attack. It may only be identified later through an ECG or other medical investigations.

How is a Heart Attack Treated?

Heart attack treatment aims to restore blood flow to the heart muscle, limit tissue damage and prevent complications. 

Treatment may involve the following:

Doctors assess symptoms, vital signs and medical history while arranging urgent investigations. An electrocardiogram (ECG) records the heart's electrical activity, while blood tests, including cardiac troponin, help identify heart muscle injury.

Depending on the clinical situation, treatment may include antiplatelet medicines to reduce clot formation, anticoagulants to limit clot growth and other medicines to manage pain, blood pressure or the heart's workload.

Percutaneous coronary intervention (PCI) may be performed to restore blood flow through a blocked coronary artery. A catheter is used to reach the affected artery, and a balloon may be inflated to open the blockage. A stent is often placed to help keep the artery open.

In selected cases, coronary artery bypass grafting (CABG) may be recommended to create an alternative route for blood to reach the heart muscle.

What Should You Do If Someone Has a Heart Attack?

A suspected heart attack requires urgent medical assistance. Taking the right steps while waiting for emergency services can help the person receive timely care.

The immediate steps include:

• Call Emergency Services: Contact emergency services immediately. In India, the emergency number is 112. Do not wait to see whether the symptoms improve.

• Help the Person Rest: Ask the person to stop any physical activity and rest in a comfortable position while waiting for medical assistance.

• Follow Medical Instructions: Follow the emergency dispatcher's guidance. Aspirin may be recommended in some circumstances, but it is not suitable for everyone. Medical advice should be followed, particularly if there is an allergy or a risk of bleeding.

• Monitor Their Condition: Stay with the person and watch for changes in consciousness or breathing. Do not leave them alone while waiting for help.

• Start CPR if Necessary: If the person becomes unresponsive and is not breathing normally, begin cardiopulmonary resuscitation (CPR) and use an automated external defibrillator (AED), if available. Follow the emergency dispatcher's instructions.

Consult Today

A heart attack can be life-threatening, and its symptoms are not always as obvious as many people expect. Since timely medical attention can make a significant difference to the outcome, it is important to take unusual chest discomfort, breathlessness or other possible warning signs seriously. If there are concerns about heart health or symptoms that need evaluation, consult a cardiologist for a thorough assessment and appropriate medical guidance.

Despite being the leading cause of cancer cases and deaths worldwide (source: WHO), lung cancer rarely makes it to the headlines. What makes the scenario more concerning is the common misconception that it only affects people who smoke, which is far from the truth. Lung cancer can affect non-smokers too, with several other factors increasing a person's risk. Misconceptions like these highlight why awareness is so important. To help increase awareness about this life-threatening disorder, Lung Cancer Awareness Month is observed every year in the month of November. In line with the observance, today we'll understand why the month matters, the warning signs to look out for, and the steps you can take to lower your risk.

About Lung Cancer Awareness Month

Lung Cancer Awareness Month is observed every November to bring attention to one of the leading causes of cancer-related deaths worldwide. Awareness initiatives began in the United States in the 1990s, initially taking the form of a dedicated awareness day before expanding into week-long and month-long campaigns. Today, healthcare organisations, advocacy groups and communities in several countries participate in these efforts to educate the public about lung cancer.

The observance highlights the importance of recognising symptoms, understanding risk factors and seeking timely medical advice. It also challenges the stigma surrounding lung cancer, particularly the assumption that it only affects smokers. By advocating for better access to care, supporting patients and their families, and encouraging continued research, the month promotes a more informed and compassionate approach to the disease.

Understanding Lung Cancer and its Types

Lung cancer develops when abnormal cells in the lungs grow uncontrollably, forming tumours that can interfere with normal lung function and may spread to other parts of the body. It is one of the most commonly diagnosed cancers worldwide and can affect both smokers and non-smokers. 

Based on the type of cells involved and how the cancer grows, there are two main lung cancer types:

• Non-small cell lung cancer (NSCLC): This is the most common type of lung cancer, accounting for approximately 85% of cases. It includes adenocarcinoma, squamous cell carcinoma and large cell carcinoma. These cancers generally grow and spread more slowly than small cell lung cancer, although their behaviour varies depending on the subtype and stage.

• Small cell lung cancer (SCLC): This type accounts for approximately 10% to 15% of lung cancer cases. It tends to grow and spread more quickly than non-small cell lung cancer and is strongly associated with smoking. Early diagnosis and appropriate treatment are important in managing the disease.

What are the Early Signs of Lung Cancer?

Lung cancer may not cause noticeable symptoms in its early stages, which is one reason it can go undetected for some time. When symptoms do appear, they may resemble those of common respiratory illnesses. Some early symptoms of lung cancer to look out for include:

• Persistent Cough: A cough that does not go away or gradually worsens over time.

• Coughing up Blood: Blood in the sputum, even in small amounts, warrants prompt medical assessment.

• Shortness of Breath: Difficulty breathing during routine activities or breathlessness that is new or worsening.

• Chest Pain: Discomfort or pain in the chest that may worsen with deep breathing, coughing or laughing.

• Recurring Infections: Repeated episodes of bronchitis or pneumonia, particularly in the same area of the lung.

• Unexplained Weight Loss: Losing weight without changing your diet or activity levels.

• Persistent Fatigue: Feeling unusually tired or weak without an obvious explanation.

• Voice Changes: Hoarseness or a persistent change in the voice.

These symptoms do not necessarily indicate lung cancer, as they can occur with other conditions too.

What Increases Your Risk of Lung Cancer?

Smoking is the leading risk factor for lung cancer, but it is not the only one. Several environmental, occupational and personal factors can contribute to the development of the disease. The main risk factors include:

• Tobacco Smoking: Cigarette smoking is responsible for most lung cancer cases. The risk generally increases with the duration and amount of smoking.

• Second-Hand Smoke: Regular exposure to smoke from other people's cigarettes can increase the risk of developing lung cancer.

• Air Pollution: Long-term exposure to outdoor air pollution, including fine particulate matter, is associated with an increased risk.

• Radon Exposure: Radon is a naturally occurring radioactive gas that can accumulate indoors and damage lung tissue when inhaled over time.

• Occupational Exposure: Contact with substances such as asbestos, arsenic, diesel exhaust and certain industrial chemicals can increase lung cancer risk.

• Family History: Having a close relative with lung cancer may be associated with a higher risk, partly due to shared genetic and environmental factors.

• Previous Radiation Therapy: Radiation treatment to the chest for certain cancers may increase the risk of developing lung cancer later in life.

Having one or more risk factors does not mean a person will necessarily develop lung cancer. Similarly, people without recognised risk factors can still develop the disease.

Why Early Detection Can Save Lives

Early detection can make a meaningful difference in lung cancer care. When the disease is diagnosed before it has spread to other parts of the body, treatment may be more effective, and patients may have more treatment options available to them. 

There are two important ways lung cancer can be detected early:

• Early Diagnosis: This involves identifying the cause of symptoms as soon as possible. If you experience a persistent cough, unexplained breathlessness or other concerning changes, a healthcare professional may recommend imaging tests and, where necessary, a biopsy to determine the cause.

• Screening: Screening looks for lung cancer before symptoms appear. Low-dose computed tomography (LDCT) scans can help detect lung cancer in certain people at high risk, particularly those with a significant history of smoking. Screening eligibility depends on individual risk factors and applicable clinical guidelines.

Small Steps for Healthier Breaths: How Can You Lower Your Lung Cancer Risk

Not every case of lung cancer can be prevented, but reducing exposure to known risk factors can help lower your chances of developing the disease. Here are some practical steps to consider:

Avoiding tobacco is one of the most effective ways to reduce lung cancer risk. If you smoke, quitting can benefit your health at any age. Consider speaking to a healthcare professional about cessation programmes, counselling or treatments that can help you quit.

Exposure to other people's tobacco smoke can also increase lung cancer risk. Keep your home and car smoke-free, and avoid environments where you are regularly exposed to tobacco smoke.

Air pollution is a recognised lung cancer risk factor. Where possible, check local air quality reports, limit strenuous outdoor activity during periods of high pollution and improve indoor ventilation when outdoor conditions allow. These steps may reduce exposure, although they cannot eliminate the risk entirely.

Some workplaces expose people to carcinogens such as asbestos, silica and diesel exhaust. Follow workplace safety procedures, use appropriate protective equipment and raise concerns about unsafe exposure with your employer or occupational health team.

Discuss your personal and family medical history, smoking history and potential environmental exposures with a healthcare professional. They can help you understand your risk and determine whether lung cancer screening is appropriate for you. Avoid getting scans without medical guidance, as screening is intended for specific groups and has potential benefits and limitations.

How Can You Support People Living With Lung Cancer

A lung cancer diagnosis can affect every aspect of a person's life, from their physical health to their emotional well-being and relationships. Here are some ways you can offer support.

Give the person space to talk about their feelings, concerns and treatment experience. Avoid making assumptions about how they developed lung cancer or suggesting that their diagnosis is a result of their choices. A non-judgemental conversation can help them feel heard and respected.

Treatment can make everyday tasks more difficult. You can offer to accompany someone to medical appointments, help with transport, prepare meals or assist with household responsibilities. Ask what they need instead of assuming what would be most helpful.

Living with cancer can bring feelings of fear, uncertainty and isolation. Encourage patients to speak with a counsellor, join a cancer support group or seek help from a mental health professional if they feel overwhelmed. Respect their preferences and give them time to process their emotions.

Help patients and caregivers find trustworthy information about treatment options, supportive care and available resources. Encourage them to discuss medical questions with their healthcare team rather than relying on unverified online advice.

Lung cancer can affect smokers and non-smokers alike. Avoid language that blames patients for their illness, and help challenge misconceptions when you encounter them. Promoting a more understanding attitude can make it easier for people to seek help and receive the support they deserve.

Take Action for Healthier Lungs and Brighter Futures

Lung Cancer Awareness Month is an opportunity to learn more about the disease, challenge common misconceptions and take meaningful steps towards better lung health. Most importantly, pay attention to changes in your health and encourage your loved ones to do the same. If you notice persistent or concerning symptoms, such as a cough that does not go away, unexplained breathlessness or coughing up blood, consult a pulmonologist promptly for an appropriate evaluation. Early medical assessment can help identify the cause of these symptoms and ensure that you receive the care you need.

Stomach cancer continues to be a significant health concern, with an estimated 642,000 deaths worldwide in 2024 (Source: WHO). Making the scenario more concerning is its silent nature - stomach cancer in its early stages is often asymptomatic or causes non-specific symptoms, which can delay diagnosis, at which point the treatment options are more limited. Stomach Cancer Awareness Month, observed every November, aims to address this by promoting understanding of the disease, its warning signs and the importance of timely medical consultation. In this article, we’ll take a closer look at the observation’s purpose, and explore the causes, symptoms, diagnosis and treatment pathways for stomach cancer.

About Stomach Cancer Awareness Month

Stomach Cancer Awareness Month is observed every November to raise awareness about stomach cancer. The observance gained recognition in the United States in 2010 through efforts led by the nonprofit organisation No Stomach For Cancer, which works to support stomach cancer research, education and patient advocacy. Its establishment helped bring greater attention to a disease that can be difficult to recognise in its early stages.

It highlights the importance of recognising stomach cancer symptoms, understanding risk factors and seeking timely medical advice. The observance encourages people to look beyond common digestive complaints and learn when persistent symptoms may need medical evaluation.

The month also provides an opportunity to educate people about how stomach cancer develops, the role of factors such as H. pylori infection, and the diagnostic and treatment options available. By making reliable information more accessible, the campaign aims to encourage informed health decisions and promote earlier medical evaluation when concerns arise.

Understanding Stomach Cancer

Stomach cancer, also known as gastric cancer, develops when cells in the stomach begin to grow abnormally and multiply uncontrollably. It usually starts in the stomach's inner lining and may spread into deeper layers or nearby organs as it progresses. The most common type is gastric adenocarcinoma, which develops in the cells that produce mucus and other fluids in the stomach lining. Early stomach cancer may not cause noticeable symptoms, and those that do appear can resemble common digestive problems, such as indigestion or bloating. This can make the condition difficult to recognise without medical evaluation. 

Types of Stomach Cancer

Stomach cancer can develop from different types of cells in the stomach. The main types include:

Adenocarcinoma is the most common type of stomach cancer, accounting for more than 90% of cases. It develops in the glandular cells lining the stomach, which produce mucus and other digestive fluids. This cancer can occur in different parts of the stomach and may grow into deeper layers or spread to other organs if left untreated. 

Gastrointestinal stromal tumours (GISTs) develop from specialised cells in the wall of the digestive tract, most commonly in the stomach. Their behaviour varies, with some growing slowly and others being more aggressive. Treatment depends on the tumour's size, location and likelihood of spreading.

Gastric lymphoma is a type of cancer that develops in the immune cells within the stomach. Some forms, including mucosa-associated lymphoid tissue (MALT) lymphoma, are associated with H. pylori infection. Treatment may involve antibiotics to eradicate the infection, medicines, radiotherapy or other cancer therapies, depending on the type and extent of the disease.

Gastric neuroendocrine tumours develop from hormone-producing cells in the stomach. Some grow slowly, while others can be more aggressive. Their treatment depends on factors such as tumour size, grade and whether the cancer has spread.

What Increases the Risk of Stomach Cancer?

Stomach cancer does not have one single cause. Several factors can increase the likelihood of developing the disease including: 

• H. pylori Infection: Long-term infection with Helicobacter pylori, a bacterium that can cause inflammation of the stomach lining, is a major risk factor for stomach cancer. Over time, the infection may lead to changes in the stomach lining that increase cancer risk.

• Family History: Having a parent, sibling or child who has had stomach cancer can increase the risk. Certain inherited conditions, including hereditary diffuse gastric cancer, can also raise the likelihood of developing the disease.

• Dietary Habits: Regularly eating large amounts of salted, smoked or poorly preserved foods may increase the risk. Diets low in fruit and vegetables have also been associated with a higher risk.

• Smoking: Tobacco use increases the risk of stomach cancer. Quitting smoking can help reduce this risk over time and improve overall health.

• Age: The risk generally increases with age, although stomach cancer can occur in younger adults too.

• Existing Stomach Conditions: Chronic atrophic gastritis, intestinal metaplasia and pernicious anaemia are among the conditions associated with an increased risk.

• Excess Body Weight: Being overweight or obese is associated with a higher risk of cancer in the upper part of the stomach, particularly near the junction with the oesophagus.

What are the Early Signs of Stomach Cancer?

Stomach cancer may not cause noticeable symptoms in its early stages. When symptoms do appear, they can resemble common digestive conditions, which makes it important to pay attention to persistent or unusual changes. Possible signs include: 

• Persistent indigestion: Repeated indigestion or discomfort in the upper abdomen that does not settle or keeps returning.

• Bloating: Frequent bloating or a feeling of fullness after eating, even when the meal is small.

• Reduced Appetite: Eating less than usual because of a lack of appetite or discomfort after meals.

• Nausea: Recurrent nausea, sometimes accompanied by vomiting.

• Abdominal Discomfort: Persistent pain or discomfort in the upper abdomen.

• Unexplained Weight Loss: Losing weight without making changes to diet or physical activity.

• Difficulty Swallowing: Trouble swallowing food, particularly when the tumour affects the upper part of the stomach or the junction with the oesophagus.

• Unusual Fatigue: Feeling unusually tired or weak, which may occur if bleeding from the tumour leads to anaemia.

How is Stomach Cancer Diagnosed?

If stomach cancer is suspected, a doctor may recommend several tests to identify the cause of the symptoms, confirm whether cancer is present and determine how far it has spread. The diagnostic process usually involves the following steps: 

The doctor begins by asking about symptoms, how long they have been present and whether there is a family history of stomach cancer. A physical examination may follow, along with blood tests to check for anaemia or other abnormalities. These tests can provide useful clues, but they cannot confirm stomach cancer on their own.

An upper gastrointestinal endoscopy allows the doctor to examine the lining of the oesophagus, stomach and upper small intestine using a thin, flexible tube with a camera. If an abnormal area is found, a small tissue sample may be collected for examination.

A biopsy is the main way to confirm a diagnosis of stomach cancer. The tissue sample collected during endoscopy is examined under a microscope to identify cancer cells and determine the type of tumour. Additional laboratory tests may help identify characteristics that can guide treatment.

If cancer is confirmed, imaging tests such as CT scans may be used to check whether it has spread to nearby tissues, lymph nodes or other organs. In selected cases, the doctor may recommend an endoscopic ultrasound, PET scan or laparoscopy to assess the extent of the disease.

What Treatment Options are Available for Stomach Cancer?

Treatment depends on the type of stomach cancer, its stage, tumour characteristics and the person's overall health. A multidisciplinary team may include gastroenterologists, surgical oncologists, medical oncologists, radiologists and other specialists. The main treatment options include:

Surgery may be recommended when the cancer can be removed safely. Depending on its location and extent, the surgeon may remove part of the stomach, known as a partial gastrectomy, or the entire stomach, known as a total gastrectomy. Nearby lymph nodes may also be removed to assess and treat the disease.

After surgery, eating habits and nutritional needs may change. Dietary guidance and follow-up care can help manage these changes during recovery.

Chemotherapy uses medicines to destroy cancer cells or stop them from growing. It may be given before surgery to shrink the tumour, after surgery to reduce the risk of recurrence, or as a primary treatment when surgery is not suitable. In advanced cases, it may also help control the disease and relieve symptoms.

Radiotherapy uses high-energy radiation to destroy cancer cells. It may be combined with chemotherapy in selected cases or used to relieve symptoms, depending on the location and extent of the cancer.

Targeted therapy works on specific proteins or molecular changes that help cancer cells grow. Tests on tumour tissue may identify whether a person is likely to benefit from a particular targeted medicine.

Immunotherapy helps the immune system recognise and attack cancer cells. It may be suitable for certain stomach cancers, depending on test results, the stage of the disease and previous treatments.

Supportive or palliative care helps manage symptoms, nutritional difficulties, pain and treatment side effects. It can be provided alongside cancer treatment to improve comfort and quality of life. The appropriate treatment plan should be discussed with the specialist team, including its potential benefits, side effects and expected outcomes.

Take a Step Towards Better Stomach Health

Stomach Cancer Awareness Month is a good time to pay attention to symptoms that do not go away. If you have ongoing indigestion, bloating or a loss of appetite, or you are worried about your own risk because of a family history of stomach cancer or a past H. pylori infection, do not wait for it to settle on its own. A gastroenterologist at Sterling Hospitals can review your symptoms and medical history, explain what could be causing them and advise whether you need tests such as an endoscopy. Consult a gastroenterologist at Sterling Hospitals today, so that any concern is checked early and you get clear answers.

Our bones are continually breaking down and rebuilding through a natural cellular process. However, when the rate of bone breakdown outpaces new bone formation, whether due to aging, hormonal shifts, or underlying health conditions, it leads to osteoporosis, a condition that severely weakens bones. Because bone loss occurs gradually without noticeable symptoms, many people do not realise they have osteoporosis until they suffer a fracture. Raising global awareness about early detection and prevention is essential, which is precisely the mission of World Osteoporosis Day.

Read on to understand the significance of World Osteoporosis Day 2026, what causes osteoporosis across different life stages, how it affects bone health, and the practical steps you can take to keep your bones strong and healthy.

About World Osteoporosis Day

World Osteoporosis Day was first observed on 20 October 1996, launched by the UK's National Osteoporosis Society with support from the European Commission. Since 1997, the International Osteoporosis Foundation (IOF) has led the global campaign, bringing together healthcare professionals, patient organisations and health authorities to raise awareness about osteoporosis and bone health.

The significance of World Osteoporosis Day lies in drawing attention to osteoporosis, a condition that often remains undiagnosed until a fracture occurs. The day highlights the importance of early detection, timely treatment and preventive measures to reduce bone loss and fracture risk. It also encourages people to prioritise bone health through balanced nutrition, regular exercise and appropriate medical care, helping preserve mobility, independence and quality of life at every age.

Theme for World Osteoporosis Day 2026

The theme for World Osteoporosis Day 2026 is “Build, Protect, Strengthen Your Bones for Life.” that highlights the importance of maintaining bone health throughout life. It encourages people to take proactive steps to build stronger bones, protect them from bone loss and strengthen them through healthy lifestyle choices and appropriate medical care.

The campaign focuses on three key actions:

• Build: Support bone development through adequate calcium and vitamin D intake, a balanced diet and regular weight-bearing exercise.

• Protect: Reduce the risk of bone loss by understanding osteoporosis risk factors, staying physically active and taking steps to prevent falls.

• Strengthen: Prioritise bone health through early diagnosis, appropriate treatment and habits that help maintain bone strength as you age.

The key message is that bone health requires attention at every stage of life. By making informed choices and seeking medical advice when needed, people can help reduce their risk of osteoporosis and fractures.

What is Osteoporosis?

Osteoporosis is a bone condition that develops when the body loses too much bone, makes too little new bone, or both. This causes bones to become weak, less dense and more prone to fractures, sometimes even after a minor fall or a simple movement. Although it can affect people of all ages, the risk increases as people grow older, particularly among women after menopause.

Our bones are living tissues that constantly undergo a process called bone remodelling, in which old bone tissue is broken down and replaced with new bone. However, when bone breakdown begins to outpace new bone formation, bone density gradually decreases. As a result, bones become more fragile and susceptible to fractures, especially in areas such as the hips, spine and wrists.

Often referred to as a silent disease, osteoporosis may not cause noticeable symptoms in its early stages. Many people only discover they have it after experiencing a fracture. This is why understanding the condition, recognising risk factors and seeking medical assessment when appropriate are important for protecting bone health and reducing the risk of complications.

What Causes Osteoporosis?

While ageing is a major risk factor, several other factors can increase a person's likelihood of developing the condition. These include:

• Ageing: As people grow older, bone formation may slow down while bone loss increases. This gradually reduces bone density and makes bones more fragile.

• Hormonal Changes: Oestrogen levels decline significantly during menopause, accelerating bone loss. Low testosterone levels can also increase the risk of osteoporosis in men.

• Calcium Deficiency: Calcium is essential for building and maintaining strong bones. Consistently low calcium intake can affect bone development and maintenance.

• Vitamin D Deficiency: Vitamin D helps the body absorb calcium from food. Low vitamin D levels can reduce calcium absorption and affect bone health.

• Physical Inactivity: Weight-bearing activities and muscle-strengthening exercises help maintain bone strength. A sedentary lifestyle can contribute to bone loss over time.

• Genetics: A family history of osteoporosis or fractures resulting from minor falls can increase a person's risk.

• Smoking and Alcohol: Smoking and excessive alcohol consumption can interfere with normal bone remodelling and contribute to bone loss.

• Medical Conditions and Medicines: Conditions such as an overactive thyroid, coeliac disease and rheumatoid arthritis can affect bone health. Long-term use of corticosteroids, such as prednisolone, can also increase osteoporosis risk.

Who is at Risk of Osteoporosis?

Osteoporosis can affect people of all ages, but certain individuals are more likely to develop the condition. The groups at a higher risk of osteoporosis include:

• Postmenopausal Women: The decline in oestrogen levels after menopause accelerates bone loss, increasing the risk of osteoporosis.

• Older Adults: Bone density naturally declines with age, making older adults more susceptible to fractures.

• People with a Family History: Individuals whose parents have osteoporosis or a history of hip fractures may have a higher risk of developing the condition.

• People with Low Body Weight: Individuals with a low body mass index (BMI) may have lower bone mass and a greater risk of fractures.

• People with Certain Medical Conditions: Those with conditions such as rheumatoid arthritis, coeliac disease, hyperthyroidism or malabsorption disorders may experience accelerated bone loss.
• Individuals Taking Certain Medicines: Long-term use of corticosteroids and certain other medications can interfere with bone metabolism.

• People with Previous Fractures: Individuals who have experienced fractures following minor falls or everyday activities may have underlying bone weakness and a higher risk of fractures in the future.

What are the Signs and Symptoms Of Osteoporosis?

Osteoporosis is often called a silent disease because it usually does not cause pain or noticeable symptoms during its early stages. In many cases, the first indication is a fracture that occurs following a minor fall or movement.

As the condition progresses, some signs may become noticeable. These include:

• Unexpected Fractures: A fracture following a minor fall, a light impact or routine activity may indicate reduced bone strength.

• Loss Of Height: Gradual height loss over the years can occur due to compression fractures in the vertebrae.

• Changes In Posture: A stooped or hunched posture may develop when weakened spinal bones collapse or compress.

• Persistent Back Pain: Sudden or ongoing back pain can sometimes indicate a vertebral fracture, particularly when accompanied by height loss or postural changes.

• Reduced Mobility: Fractures, pain and changes in spinal alignment can make everyday activities, such as walking, bending or lifting objects, more difficult.

It is important to note that back pain and changes in posture can have several causes. If you experience these symptoms, particularly after a minor fall or without an obvious injury, seek medical evaluation rather than assuming they are due to ageing.

How is Osteoporosis Treated?

Osteoporosis treatment aims to slow bone loss, improve bone strength where possible and reduce the risk of fractures. 

Treatment options may include the following:

Doctors may prescribe medicines to reduce bone breakdown or stimulate new bone formation, depending on the severity of osteoporosis and the patient's fracture risk. 

Adequate calcium and vitamin D intake supports bone maintenance and helps ensure that osteoporosis medication works as intended. A doctor may recommend dietary changes or supplements if a deficiency or inadequate intake is identified.

Food sources of calcium include dairy products, calcium-set tofu and certain green vegetables. Vitamin D can be obtained from selected foods, fortified products and sunlight exposure, although individual requirements vary.

Appropriate exercise helps improve muscle strength, balance and physical function. A physiotherapist may recommend weight-bearing activities, resistance exercises and balance training according to the person's bone health and fracture history.

People with severe osteoporosis or existing vertebral fractures may need to avoid high-impact activities and certain movements involving forceful spinal bending or twisting.

How Can Osteoporosis be Prevented?

Although osteoporosis cannot always be prevented, certain lifestyle changes can help maintain bone strength and reduce the risk of fractures. Here are some measures to consider:

Include calcium-rich foods such as milk, yoghurt, cheese, calcium-set tofu and suitable green vegetables in your daily diet. Calcium supports bone structure, while adequate protein helps maintain the muscles that support movement and balance. If your diet does not provide enough calcium, consult a healthcare professional before taking supplements.

Vitamin D helps the body absorb calcium and maintain healthy bones. Include suitable sources such as oily fish, eggs and fortified foods in your diet. Depending on your sun exposure, diet and individual health needs, your doctor may recommend vitamin D supplements or testing.

Make weight-bearing activities, such as walking and stair climbing, part of your routine. Add muscle-strengthening exercises to help maintain bone and muscle health. Balance training can also help reduce the risk of falls. If you have osteoporosis or a history of fractures, seek professional guidance before starting a new exercise programme.

Smoking and excessive alcohol consumption can negatively affect bone health. Avoid tobacco and keep alcohol intake within recommended limits. Maintaining a balanced diet and a healthy body weight can also support bone health over the long term.

Do not wait for a fracture if you have risk factors such as early menopause, long-term corticosteroid use or a family history of hip fractures. Speak to your doctor about whether a bone mineral density test, commonly performed using a DXA scan, is appropriate for you. Early assessment can help identify bone loss and guide preventive care.

Prioritise Bone Health Today and Every Day

World Osteoporosis Day reminds us that protecting bone health starts with recognising the risks before they lead to complications. So if you have risk factors or have experienced a fracture after a minor fall, it is important to seek medical advice. Consult an orthopaedist at Sterling Hospitals to identify potential concerns and understand your bone health. They can guide you towards appropriate care to help maintain your mobility and quality of life as you age.
