UTIs can affect different parts of your urinary tract, including your bladder (cystitis), urethra (urethritis) or kidneys (kidney infection). Most UTIs can be easily treated with antibiotics.
Check if it’s a UTI
Symptoms of a UTI include:
- needing to pee suddenly or more often than usual
- pain or a burning sensation when peeing
- smelly or cloudy pee
- blood in your pee
- pain in your lower tummy
- feeling tired and unwell
- in older people, changes in behaviour such as severe confusion or agitation
See a GP if:
- you’re a man with symptoms of a UTI
- you’re pregnant and have symptoms of a UTI
- your child has symptoms of a UTI
- you’re caring for someone elderly who may have a UTI
- you haven’t had a UTI before
- you have blood in your pee
- your symptoms don’t improve within a few days
- your symptoms come back after treatment
If you have symptoms of a sexually transmitted infection, you can also get treatment from a sexual health clinic.
Your doctor or nurse may prescribe antibiotics to treat a UTI.
Once you start treatment, the symptoms should start to clear up within 5 days in adults and 2 days in children.
It’s important to finish the whole course of antibiotics, even if you start to feel better.
Some people with a severe UTI may be referred to hospital for treatment and tests. You may need to stay for a few days. Hospital treatment is more likely for men and children with a UTI.
Treating recurring UTIs
If your UTI comes back any time after treatment, you’ll usually be prescribed a longer course of antibiotics.
If you keep getting UTIs and regularly need treatment, your GP may give you a repeat prescription for antibiotics.
Things you can do yourself
Mild UTIs often pass within a few days. To help ease pain while your symptoms clear up:
- take paracetamol – you can give children liquid paracetamol
- place a hot water bottle on your tummy, back or between your thighs
- rest and drink plenty of fluids – this helps your body to flush out the bacteria
It may also help to avoid having sex until you feel better. You can’t pass a UTI on to your partner but sex may be uncomfortable.
Causes of UTIs
UTIs are usually caused by bacteria from poo entering the urinary tract. The bacteria enter through the tube that carries pee out of the body (urethra).
Women have a shorter urethra than men. This means bacteria are more likely to reach the bladder or kidneys and cause an infection.
Causes of UTIs include:
- conditions that block the urinary tract – such as kidney stones
- conditions that make it difficult to fully empty the bladder – such as an enlarged prostate gland in men and constipation in children
- urinary catheters (a tube in your bladder used to drain urine)
- having a weakened immune system – for example, from type 2 diabetes, chemotherapy or HIV
