What is cystitis?
- Cystitis is inflammation of the bladder that is usually caused by a bacterial infection
- It is the most common type of urinary tract infection and affects the bladder
- It can cause symptoms that make passing urine uncomfortable and more frequent

What causes cystitis?
- Cystitis usually develops when bacteria enter the bladder through the urethra and multiply
- E coli is the most common bacteria responsible for bladder infections
- In some people, medicines, radiation therapy or chemicals in certain hygiene products may also irritate the bladder and cause cystitis
What are the common symptoms of cystitis?
- You may feel the need to pass urine more often, even if only a small amount comes out
- You may have pain, burning or discomfort while passing urine
- Your urine may appear cloudy, darker than usual, contain blood or have a strong smell
- You may also feel pressure or pain in the lower abdomen or pelvic area
Who is more likely to develop cystitis?
- Women are more likely to develop cystitis because bacteria have a shorter distance to reach the bladder
- Pregnancy and menopause can increase the risk because of changes in the body
- People with diabetes, urinary catheters, kidney stones or urinary tract problems have a higher chance of developing cystitis
- Having had cystitis before also increases the risk of getting another infection
Is cystitis contagious?
- No, cystitis cannot be passed from one person to another like a cold or flu
- Sexual activity may allow bacteria to enter the urinary tract and increase the risk of infection
- Passing urine after sex and practising good hygiene may help reduce this risk
How is cystitis diagnosed?
- Your healthcare professional will ask about your symptoms and medical history
- A urine sample is usually tested to look for bacteria, blood or other signs of infection
- A urine culture may be done to identify the bacteria causing the infection and guide treatment
- If symptoms continue or return, additional tests may be recommended to look for other causes
How is cystitis treated?

- Pass urine soon after sexual activity to help remove bacteria from the urethra
- Speak to your healthcare professional if you have frequent bladder infections, as additional preventive treatments may be available
Can cystitis spread to the kidneys?
- Yes, if cystitis is not treated, the infection can spread from the bladder to the kidneys
- A kidney infection is more serious and usually needs prompt medical treatment
- Early treatment of cystitis helps reduce the risk of kidney infection
When should I seek medical help for cystitis?
- Contact your healthcare professional if you have symptoms of cystitis that last for more than a few days
- Seek medical advice if your symptoms return after completing antibiotics

Are there foods and drinks I should avoid while recovering?
