UTI treatment options overview

Overview

A urinary tract infection (UTI) is an infection in any part of the urinary system, including the kidneys, ureters, bladder, or urethra. Most UTIs affect the bladder and urethra, and they are usually easy to treat with medicines prescribed by a doctor.

Yes, UTIs are one of the most common infections. Many people will have at least one in their lifetime.

Anyone can get a UTI, but they are much more common in women. People with diabetes, older adults, people with urinary catheters, and people with a weakened immune system are also at higher risk.

Symptoms

Common symptoms

• Burning or pain when urinating
• Feeling the need to urinate often, but only passing a little urine
• Cloudy, dark, or strong-smelling urine
• Pain or pressure in the lower belly or pelvic area
• Feeling tired or generally unwell

Symptoms in children

• Fever or chills
• Fussiness or irritability
• Poor feeding or vomiting
• Wetting themselves even if they are potty-trained
• Unusual drowsiness or lack of energy

Symptoms in older adults

• Confusion or changes in mental state
• New falls or unsteadiness
• Behavior changes, such as agitation or withdrawal
• New or worsening incontinence
• A burning sensation may be absent or harder to notice

Causes

Main causes

• Bacteria, usually E. coli from the digestive tract, entering the urinary tract through the urethra
• Less commonly, viruses or fungi may cause an infection
• In some cases, bacteria can travel up from the bladder to the kidneys

Risk factors

• Female anatomy (shorter urethra)
• Sexual activity
• Using spermicides or a diaphragm for birth control
• Menopause and changes in vaginal bacteria
• Blockage or narrowing of the urinary tract (for example, an enlarged prostate or kidney stone)
• Using a urinary catheter
• A weakened immune system
• Not drinking enough fluids or holding urine for long periods

When to see a doctor

See a doctor urgently if:

• You have high fever, chills, back or side pain, or blood in your urine — call emergency services right away or go to an emergency room
• You are unable to urinate
• You have severe pain in your belly or pelvis

Book a routine appointment if:

• You notice burning, frequency, urgency, or cloudy urine
• You have symptoms that last more than a day
• You are pregnant and think you may have a UTI
• You have had UTIs before and they keep coming back

Diagnosis

A doctor will ask about your symptoms, take a medical history, and test a sample of your urine. They may also do a physical exam.

Tests that may be done

• Urine dipstick test: a quick test that checks for signs of infection, such as nitrites or white blood cells
• Urine culture: a lab test to identify the exact bacteria causing the infection and see which antibiotics are likely to work
• Imaging tests (like an ultrasound or CT scan) or a cystoscopy (a small camera to look inside the bladder) if infections are recurrent or complicated

What to expect at your appointment

You will be asked to provide a clean-catch urine sample. This means you clean the area, start urinating, then collect urine midstream in a sterile cup. Results for a culture may take a day or two. The doctor may also ask about your sexual history and any other health conditions.

Treatment

The right treatment depends on whether the infection is in the lower urinary tract or has reached the kidneys, and on your overall health. Most UTIs are treated with a short course of antibiotics. Your doctor will choose the treatment that fits your situation.

Self-care at home

• Drink plenty of water to help flush out bacteria
• Urinate often and do not hold your urine for long
• Empty your bladder completely each time
• Avoid caffeine, alcohol, and spicy or acidic foods while symptoms last
• Use a heating pad on your lower belly for comfort
• Empty your bladder before and after sexual activity

Medical treatments

Antibiotics are the main treatment for most UTIs. Your doctor will prescribe an antibiotic that targets the bacteria causing your infection. It is very important to take the medicine exactly as prescribed, even if you feel better before you finish it. For a simple bladder infection, a short course of a few days is often enough. For a more complicated infection involving the kidneys, you may need a longer course, or antibiotics given through a vein in a hospital. If you have recurrent UTIs, your doctor may discuss a plan such as a low-dose antibiotic for a longer period, a single dose after sex, or a hormonal treatment (like a vaginal cream or ring) for postmenopausal women. These options are decided based on your specific needs.

When is surgery considered?

Surgery is rarely needed for UTIs. It may be considered if there is a structural problem that keeps urine from flowing normally, such as a kidney stone, an enlarged prostate, or a blockage. In these cases, a specialist called a urologist will evaluate you and recommend the best approach.

Living with this condition

During treatment, rest as needed and drink extra fluids. Finish your full prescribed course, even if you feel better. If symptoms do not improve within two days, contact your healthcare provider.

Lifestyle tips

• Wipe from front to back after using the toilet
• Urinate right after sex to flush out bacteria
• Stay well hydrated throughout the day
• Avoid holding urine for long periods
• Wear cotton underwear and avoid tight, damp clothing
• Avoid irritating feminine products like douches or sprays

Diet and exercise

There is no specific diet that cures a UTI, but staying well-hydrated is key. Some people drink unsweetened cranberry juice, but evidence is not strong, and it should not replace medical treatment. Exercise is fine once you feel comfortable, but during severe symptoms it is okay to rest.

Mental health and emotional wellbeing

A UTI can be uncomfortable and frustrating, especially if it keeps returning. It is normal to feel worried or anxious. Talk with your doctor if these feelings are affecting your daily life. If you need immediate mental health support, reach out to your local crisis helpline or emergency service.

Prevention

You cannot always prevent a UTI, but certain habits can lower your risk. Staying hydrated, urinating before and after sex, wiping front to back, and avoiding irritants like douches are all helpful steps.

Vaccines

There is currently no approved vaccine for preventing urinary tract infections.

Screening programmes

There is no routine screening test for UTIs in healthy people. However, if you have recurring infections, your doctor may recommend tests to look for underlying causes.

Complications

If left untreated

• An untreated UTI can spread upward to the kidneys and cause a kidney infection (pyelonephritis)
• A kidney infection can lead to permanent kidney damage
• In rare cases, the infection can enter the bloodstream and cause a life-threatening condition called sepsis
• In pregnant women, an untreated UTI can increase the risk of early labor or low birth weight

Long-term outlook

Most UTIs clear up easily with treatment, and symptoms usually improve within a few days. If you get recurrent UTIs, your healthcare provider can help you find a plan that reduces how often they happen and keeps you feeling your best. With proper care, the outlook is very good.
