Why do I keep getting cystitis?

Cystitis is a common type of Urinary Tract Infection (UTI) that typically lasts around 3 days. It’s usually caused by bacteria known as Escherichia Coli (E. Coli) entering the urethra (the tube that carries urine out of the body) and travelling up, which causes irritation of the bladder.

Generally, women are more likely to have cystitis than men; the NHS believes this is because a woman’s urethra is shorter and closer to the anus, meaning bacteria has less far to travel in order to reach the bladder.

While not typically a cause for concern, cystitis can be uncomfortable and sometimes painful. Along with some sore symptoms, you may also experience flu-like symptoms.

Some people suffer from recurring cystitis, which doctors classify as three or more occurrences in one year, or two episodes in six months. Whilst there’s no certainty as to why some people are more prone to cystitis than others, there are a number of useful everyday things to know that could help you prevent it.

I've Had Cystitis Before – Why Has It Come Back?

Unfortunately, some people are more predisposed to cystitis than others, and they may suffer from it more frequently. In such cases, a doctor may need to establish a long-term treatment plan.

There are also several things which could be increasing your risk for cystitis:

• Sexual intercourse
• Contraceptive diaphragm
• Pregnancy
• Age
• Diabetes
• Urinary catheter
• Wiping back to front, instead of front to back

Individuals with a weakened immune system, such as the elderly, are at a higher risk of infection.

While some of these are unavoidable, being mindful of these points may help reduce your risk of another bout of cystitis.

How Can I Decrease My Chances of Getting Cystitis?

The best way to decrease your chances of getting cystitis again is largely about flushing out and preventing the buildup of bacteria. Try the following tips:

• Avoid using scented soaps on intimate areas
• Try showering rather than bathing
• Drink lots of water
• Go to the toilet as soon as possible and empty your bladder fully
• Always ensure you wipe front to back
• Urinate as soon as possible after sex
• Wear loose, comfortable underwear made of breathable fabric

While cranberry juice is a popular preventative method, studies have shown it doesn't make a significant difference.

When Should I Go to The Doctor About It?

If the self-help measures aren't enough, ask your pharmacist for further advice.

If you’re still experiencing symptoms after 3 days, you may need a course of antibiotics, such as trimethoprim, to clear the infection completely.

You should also see a doctor if you have additional symptoms, including fever, blood in your urine or back pain. These symptoms may indicate a kidney infection, which will require medical treatment.

If you suffer from recurring abdominal pain and struggle to urinate frequently, you may have interstitial cystitis. This bladder condition is not well understood and usually affects middle-aged women. Antibiotics won't work here, since the issue isn't caused by bacteria. It’s essential to consult a doctor for an accurate diagnosis.
