Cystitis symptoms: what they mean and when to see a doctor

Cystitis is one of the most common reasons women visit a doctor. Recognising the signs early helps you act quickly — and know when home care is not enough.

What is cystitis?

Cystitis means inflammation of the bladder. In most cases it is caused by a bacterial infection of the lower urinary tract, usually by E. coli from the bowel. Doctors also call it a lower urinary tract infection (UTI). The NHS estimates that most women will have cystitis at least once.

Typical symptoms

  • Pain, burning or stinging when you pass urine
  • Needing to pee more often and more urgently than usual
  • Feeling you have not emptied your bladder
  • Urine that is dark, cloudy or strong-smelling
  • Pain low down in your tummy
  • Feeling generally unwell, achy or tired

Symptoms can start suddenly — often a day or two after a trigger such as intimacy, a cold day or a long journey with little to drink.

Mild cystitis sometimes settles within a few days. But recurring or severe symptoms deserve attention, because an untreated infection can travel up to the kidneys.

When to see a doctor straight away

Do not wait if you have:

fever or shivering · pain in your back or side under the ribs · nausea or vomiting · blood in your urine · symptoms during pregnancy · symptoms in a child or a man · symptoms that do not improve after two days or come back soon after treatment.

These signs can mean a kidney infection or another condition that needs medical treatment. Your GP, an out-of-hours service or a pharmacist can advise you. In the UK, many pharmacies can now assess uncomplicated UTIs in women.

What can feel like cystitis but is not

Thrush, sexually transmitted infections, bladder pain syndrome, kidney stones and menopause-related vaginal dryness can all cause similar discomfort. That is why a urine test is useful if symptoms keep returning — it shows whether bacteria are really involved.

What helps at home

  • Drink enough water so that your urine stays pale.
  • Rest and use a hot water bottle on your tummy.
  • Take paracetamol or ibuprofen if suitable for you.
  • Avoid sex until you feel better.
  • Skip alcohol, very sweet drinks and too much coffee while symptoms last.

If cystitis keeps coming back

Doctors speak of recurrent infections when they happen two or more times in six months, or three or more times in a year. Then it is worth looking at triggers, habits and support options together with your doctor — from hydration and toilet habits to cranberry and D-mannose, which many women use as part of their daily routine.

Frequently asked questions

Can cystitis go away on its own?

Mild cystitis sometimes settles within a few days. If symptoms are severe, include fever or back pain, or last longer than two days, see a doctor.

Is cystitis contagious?

No. It is not passed from person to person, although sex can push bacteria towards the urethra.

Why do I get cystitis after sex?

Movement can push bowel bacteria towards the urethra. Passing urine soon after sex helps — see our guide on cystitis after sex.

Do men get cystitis?

Less often, because their urethra is longer. In men, urinary symptoms should always be checked by a doctor.
