UTI overview for patients
Informed by recognized medical guidance
Overview
A urinary tract infection (UTI) is an infection in any part of your urinary system, which includes the kidneys, ureters, bladder, and urethra. Most UTIs affect the bladder and urethra. They happen when bacteria get into the urine and travel up the urinary tract.
Key facts
- UTIs are very common, especially in women.
- They are usually easy to treat and most people recover quickly.
- Drinking plenty of water and good bathroom habits can help prevent them.

Causes
Main causes
- Bacteria, most often from the bowel, entering the urinary tract through the urethra
- Bacteria clinging to the bladder wall and multiplying
- Less commonly, viruses or fungi causing infection
Risk factors
- Being female – the urethra is shorter and closer to the anus
- Sexual activity, especially with a new partner
- Using a urinary catheter
- Menopause, which changes the urinary tract lining
- Not emptying the bladder fully, for example due to an enlarged prostate or kidney stones
- Weakened immune system from illness or certain medicines
- Not drinking enough fluids
When to see a doctor
See a doctor urgently if:
- You have emergency symptoms like high fever, confusion, or severe pain.
- You are pregnant and have symptoms of a UTI.
- A child has symptoms of a UTI.
Book a routine appointment if:
- Your symptoms last longer than a day or two.
- You see blood in your urine.
- You keep getting UTIs.
Diagnosis
Your healthcare provider will ask about your symptoms and your health history. They will usually ask for a urine sample to test for infection.
Tests that may be done
- Urine dipstick test – a special strip dipped into your urine that shows signs of infection within a minute
- Urine culture – a sample sent to a lab to find out which bacteria are causing the infection
- If you have frequent UTIs, your doctor may recommend an ultrasound or other imaging to look at your urinary tract
What to expect at your appointment
The doctor or nurse will explain what they are doing. You will be given a clean cup to collect a small sample of urine. You may need to wait a few minutes for the result, or the sample may be sent away. Often treatment can start before the full result is back.
Treatment
UTIs are usually treated with a short course of antibiotics. The type and length of treatment depend on your symptoms, your health, and the bacteria causing the infection. It is important to take the full course exactly as prescribed.
Self-care at home
- Drink plenty of water to help flush out bacteria, unless your doctor tells you to limit fluids.
- Rest as much as you need.
- Use a warm pad or hot water bottle on your lower belly for comfort (always wrap it safely).
- Ask your pharmacist about safe pain relief options.
Medical treatments
Your doctor will prescribe an antibiotic that is safe for you. You may start feeling better within a day or two, but you must finish the whole course of antibiotics. For more serious infections, or if you cannot keep fluids down, treatment may include IV antibiotics in a hospital.
When is surgery considered?
Surgery is rarely needed for a UTI. It may be considered if there is a structural problem in the urinary tract, kidney stones, or an abscess that needs to be drained. Your doctor would only recommend this after a full assessment.
Living with this condition
While you are recovering, take your medicine as prescribed, drink extra fluids, and keep an eye on your symptoms. Most UTIs improve significantly within 48 hours of starting treatment.
Lifestyle tips
- Urinate as soon as you feel the need – don't hold it in.
- Drink enough water throughout the day.
- Wipe from front to back after using the toilet.
- Empty your bladder soon after sex.
- Avoid using perfumed products in the genital area.
Diet and exercise
There is no special diet for UTIs, but drinking plenty of water is the most helpful thing. If you feel unwell, rest. Once you feel better, you can return to your normal activities, including exercise.
Mental health and emotional wellbeing
UTIs can be uncomfortable and frustrating, especially if they keep coming back. It is normal to feel fed up or worried. Talk to your healthcare provider about your concerns – they can offer support and help you plan next steps.
Prevention
Many UTIs can be prevented with simple habits, such as drinking enough fluids, going to the toilet regularly, and keeping the genital area clean and dry. For people who get repeated UTIs, a doctor may suggest extra measures.
Vaccines
There is currently no routine vaccine that prevents UTIs. Researchers continue to study new ways to prevent them.
Screening programmes
There is no routine screening for UTIs in healthy people. Urine tests are done when you have symptoms or are at higher risk, such as during pregnancy.
Complications
If left untreated
- The infection may travel up to your kidneys, causing a kidney infection.
- Kidney infections can damage the kidneys over time.
- In rare cases, the infection can spread into the blood, causing a life-threatening condition called sepsis.
Long-term outlook
Most UTIs clear up quickly with proper treatment. Even kidney infections are usually curable with a longer course of antibiotics. The key is to see a healthcare provider early if you suspect a UTI.
