Urinary tract infections (UTIs) affect your urinary tract, including your bladder (cystitis), urethra (urethritis) or kidneys (kidney infection). UTIs may be treated with antibiotics, but they're not always needed.
Symptoms of a urinary tract infection (UTI) may include:
- pain or a burning sensation when peeing (dysuria)
- needing to pee more often than usual
- needing to pee more often than usual during the night (nocturia)
- needing to pee suddenly or more urgently than usual
- pee that looks cloudy
- blood in your pee
- lower tummy pain or pain in your back, just under the ribs
- a high temperature, or feeling hot and shivery
- a very low temperature below 36C
Your pee may also be dark or smell. If this is your only symptom, it might be because you've not been drinking enough water.
Children
Children with UTIs may also:
- have a high temperature – your child is feeling hotter than usual if you touch their neck, back or tummy
- appear generally unwell – babies and young children may be irritable and not feed or eat properly
- wet the bed or wet themselves
- be sick
Older, frail people or people with a urinary catheter
In older, frail people who have problems with memory, learning and concentration (such as dementia), and people with a urinary catheter, symptoms of a UTI may also include:
- changes in behaviour, such as acting agitated or confused (delirium)
- wetting themselves (incontinence) that is worse than usual
- new shivering or shaking (rigors)
See a GP if:
- you have symptoms of a urinary tract infection (UTI) for the first time
- your child has symptoms of a UTI
- you're a man with symptoms of a UTI
- you're pregnant and have symptoms of a UTI
- you're caring for an older, frail person who may have symptoms of a UTI
- you have symptoms of a UTI after surgery
- your symptoms get worse or do not improve within 2 days
- your symptoms come back after treatment
Ask for an urgent GP appointment or get help from NHS 111 if:
You think you, your child or someone you care for may have a urinary tract infection (UTI) and:
- have a very high temperature, or feel hot and shivery
- have a very low temperature below 36C
- are confused or drowsy
- have pain in the lower tummy or in the back, just under the ribs
- can see blood in your pee
These symptoms could mean you have a kidney infection, which can be serious if it's not treated as it could cause sepsis.
If you cannot speak to or see a GP, or your symptoms are getting worse, call 111 or get help from 111 online.
If a GP thinks you may have a urinary tract infection (UTI), they may do a urine test, although this is not always needed.
A GP may also:
- offer self-care advice and recommend taking a painkiller
- give you a prescription for a short course of antibiotics
- give you a prescription for antibiotics, but suggest you wait for 48 hours before taking them in case your symptoms go away on their own
It's important to take all the medicine you're prescribed, even if you start to feel better.
Treatment for UTIs that keep coming back (recurrent UTIs)
If your UTI comes back after treatment, or you have 2 UTIs in 6 months, a GP may:
- prescribe a different antibiotic or prescribe a low-dose antibiotic to take for up to 6 months
- prescribe a vaginal cream containing oestrogen, if you have gone through the menopause
- refer you to a specialist for further tests and treatments
In some people UTI symptoms do not go away. Short-term antibiotics do not work and urine tests do not show an infection.
This might mean you have a chronic (long-term) UTI. This can be caused by bacteria entering the lining of the bladder.
Because urine tests do not always pick up the infection and the symptoms can be similar to other conditions, chronic UTIs can be hard to diagnose.
Chronic UTIs might be treated with antibiotics that you take for a long time.
Chronic UTIs can have a big impact on your quality of life. If you have been treated for a UTI but you still have symptoms, speak to your GP about chronic UTIs and ask to be referred to a specialist.
To help ease symptoms of a urinary tract infection (UTI):
- take paracetamol up to 4 times a day to reduce pain and a high temperature
- you can give children liquid paracetamol
- rest and drink enough fluids so you pass pale urine regularly during the day
- avoid having sex
Some people take cystitis sachets or cranberry drinks and products every day to prevent UTIs from happening, which may help. But there's no evidence they help ease symptoms or treat a UTI if the infection has already started.
A pharmacist can help with UTIs
You can ask a pharmacist about treatments for a UTI.
A pharmacist can:
- offer advice on things that can help you get better
- suggest the best painkiller to take
- provide the same treatment as a GP, if it's suitable for you
- tell you if you need to see a GP about your symptoms
Urinary tract infections (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.
Things that increase the risk of bacteria getting into the bladder include:
- having sex
- pregnancy
- 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 in men and constipation in children
- urinary catheters (a tube in your bladder used to drain urine)
- having a weakened immune system – for example, people with diabetes or people having chemotherapy
- not drinking enough fluids
- not keeping the genital area clean and dry
There are some things you can try to help prevent a urinary tract infection (UTI) happening or prevent it returning.
Do
wipe from front to back when you go to the toilet
keep the genital area clean and dry
drink plenty of fluids, particularly water – so that you regularly pee during the day and do not feel thirsty
wash the skin around the vagina with water before and after sex
pee as soon as possible after sex
promptly change nappies or incontinence pads if they're soiled
Don't
do not use scented soap
do not hold your pee in if you feel the urge to go
do not rush when going for a pee – try to fully empty your bladder
do not wear tight synthetic underwear, such as nylon
do not drink lots of alcoholic drinks, as they may irritate your bladder
do not have lots of sugary food or drinks, as they may encourage bacteria to grow
do not use condoms or a diaphragm or cap with spermicidal lube on them – try non-spermicidal lube or a different type of contraception
If you keep getting a bladder infection (cystitis), there's some evidence it may be helpful to take:
- D-mannose – a sugar you can buy as a powder or tablets to take every day
- cranberry products – available as juice, tablets or capsules to take every day
Speak to your doctor before taking any of these during pregnancy.
Be aware that D-mannose and cranberry products can contain a lot of sugar.
If you're taking warfarin, you should avoid cranberry products.
