Less May Be More When Treating Urinary Tract Infections

Overview

A urinary tract infection (UTI) is an infection in the parts of the body that make and carry urine. Most UTIs affect the bladder and the tube that carries urine out of the body (the urethra). They happen when germs, usually bacteria from your bowel, get into the urinary system and multiply. The idea that 'less may be more' comes from a change in how doctors now treat simple bladder infections. For many people, a shorter course of antibiotics works just as well as a longer one. Some mild infections clear up on their own with plenty of fluids and rest. Using fewer antibiotics when they are not needed helps stop bacteria from becoming resistant, which means the medicines keep working for you and everyone else in the future.

Yes, urinary tract infections are very common. They are one of the most frequent reasons people see a doctor or nurse for a same-day appointment, and one of the most common reasons antibiotics are prescribed.

Anyone can get a UTI, but they are much more common in women, because the tube that carries urine out of the body is shorter and closer to the back passage where bacteria live. They also happen more often in babies and young children, in older adults, in people who use a catheter, in people with diabetes, and in anyone whose immune system (the body's defence system) is weaker than usual. They can also happen during pregnancy.

Symptoms

Common symptoms

• A burning, stinging or scraping feeling when you pass urine
• Needing to pee more often than usual, and suddenly
• A strong urge to go, sometimes with very little urine coming out
• Urine that looks cloudy, dark or smells stronger than usual
• Pain or a heavy feeling in the lower belly
• Blood in your urine (it may look pink or slightly red)

Symptoms in children

• Fever, sometimes the only sign in a young baby
• Being unusually sleepy, fussy or hard to settle
• Feeding less than usual or refusing feeds
• Vomiting or tummy pain
• Wetting again after being dry, or new daytime wetting
• Pain or crying when passing urine in older children

Symptoms in older adults

• New confusion or drowsiness — this can be the main sign
• Falls or a sudden loss of mobility
• New or worse leaking of urine
• Feeling generally unwell, tired or 'not themselves'
• Sometimes no usual symptoms at all, which makes it harder to spot

Causes

Main causes

• Bacteria getting into the opening of the urinary tube and travelling up to the bladder — the most common culprits normally live harmlessly in the bowel
• Not emptying your bladder fully, which lets bacteria sit and multiply
• Irritation or small injury to the urinary tube during sex
• Using a urinary catheter, which can carry bacteria into the bladder
• In some people, a blockage or a problem with the shape of the urinary system

Risk factors

• Being female — the urinary tube is shorter and closer to the back passage
• Being sexually active, especially with a new partner
• Changes after menopause, when the tissues become drier and thinner
• Not drinking enough fluids, or regularly holding on when you need to go
• Constipation (hard, difficult-to-pass stools), which lets bowel bacteria move closer to the urinary opening
• Using a diaphragm or spermicide for contraception
• Diabetes, kidney stones, or a weakened immune system
• Pregnancy, which changes the flow of urine
• Having had a UTI before — they often come back
• In older adults, needing help with washing or toileting, or living in a care setting

When to see a doctor

See a doctor urgently if:

• You have a high temperature, back pain, or you feel shivery and unwell
• You are a man with UTI symptoms
• You are pregnant and think you have a UTI
• You can see blood in your urine
• You cannot keep fluids down because of vomiting
• Symptoms are not improving after 48 hours, or they are getting worse
• Your child has a fever with no clear cause, or is unusually sleepy or difficult to wake

Book a routine appointment if:

• You keep getting UTIs — for example two or more in six months, or three or more in a year
• Mild symptoms keep coming back after treatment
• You have a long-term condition such as diabetes, kidney problems or a weakened immune system, and you get UTI symptoms
• You use a catheter and notice new symptoms
• You want to talk about prevention, or about whether you really need antibiotics

Diagnosis

A doctor or nurse will usually start by asking about your symptoms and your general health, and may ask for a urine sample. For a simple bladder infection in a healthy person, the story alone is often enough to make a likely diagnosis. Testing is used more often when the picture is unclear, when symptoms keep coming back, or when there is a reason to be more careful, such as pregnancy, being male, or having a long-term condition.

Tests that may be done

• A urine dipstick test — a strip of paper dipped in your urine that gives a quick clue about infection
• A urine culture — a sample sent to a lab to see which bacteria are present and which antibiotics are likely to work
• A pregnancy test, if there is any chance you could be pregnant
• Blood tests, if you are very unwell or the infection may have spread
• A scan of your kidneys and bladder, usually only if you have repeated infections, kidney stones, or problems passing urine
• In children, extra tests may be suggested after a confirmed infection to check how the urinary system is formed

What to expect at your appointment

You will usually be asked to give a urine sample in a small pot — it helps to catch the middle part of your pee. If a culture is sent, results can take a few days. Your clinician may treat you straight away, or may wait for results if your symptoms are mild. Either way, you should be told what to look out for and when to come back.

Treatment

Treatment depends on who you are, how unwell you feel, and whether the infection is in the bladder or has moved higher up. For a simple bladder infection in an otherwise healthy person, current thinking is often 'less may be more'. That can mean a shorter course of antibiotics than used to be given, a lower dose, or a 'wait and see' plan where you only take antibiotics if symptoms don't settle in a day or two. Sometimes no antibiotics are needed at all. Your clinician will weigh up the chance of the infection clearing by itself against the risk of it spreading, and will talk through the options with you. If you are pregnant, male, a child, older, or have a long-term condition, antibiotics are more likely to be recommended straight away. Antibiotics are not the right treatment for every case, and using them only when needed keeps them effective for the future.

Self-care at home

• Drink plenty of water through the day — pale yellow urine is a good sign you are drinking enough
• Go to the toilet when you feel the urge, and try to empty your bladder fully
• Use over-the-counter pain relief recommended by your pharmacist to ease discomfort
• A warm pack on your lower belly can help with the ache
• Rest when you can, and avoid alcohol and caffeine if they seem to make symptoms worse
• Avoid perfumed soaps, bubble baths and douches around the genital area while you heal
• If you are given a 'wait and see' prescription, keep it somewhere handy and start it only if your symptoms don't improve or get worse

Medical treatments

When antibiotics are needed, your clinician will choose one based on how unwell you are, your medical history, any allergies, whether you are pregnant, and local guidance about which antibiotics still work well. Short courses are now preferred for simple bladder infections, because they work as well as longer ones and cause fewer side effects. If a urine culture shows that a different antibiotic would suit you better, your treatment may be changed. It is important to take antibiotics exactly as advised, to finish the course if you are asked to, and never to save leftover antibiotics for another time or share them with anyone else. If your symptoms are not improving after two days, let your clinician know rather than simply stopping or restarting treatment.

When is surgery considered?

Surgery is not needed for most urinary tract infections. It may be discussed if repeated infections are caused by a physical problem — such as a kidney stone, a blockage, or an unusual shape in the urinary system, especially in children. In that situation, a specialist team would explain the options and whether an operation or procedure could reduce future infections.

Living with this condition

Most people with a bladder infection feel better within a few days. In the meantime, plan gentle days, keep water close by, and don't push yourself too hard. If you use a catheter or care for someone who does, watch for new symptoms such as cloudy urine, fever or confusion, and ask for advice early. If infections keep coming back, keep a simple diary of when they happen and what might have triggered them — it can be very useful in your appointments.

Lifestyle tips

• Drink enough fluid each day, especially in hot weather or when exercising
• Don't hold on when you need to pee — go when your body tells you
• Treat constipation early with fibre, fruit, vegetables and fluids
• Pee after sex if that seems to help you, and avoid spermicide-based contraception if infections follow sex
• Wear cotton underwear and avoid tight, non-breathable clothing
• Wash the genital area with plain water — strong soaps and douches can irritate
• Review with your clinician whether any medicines you take, such as some diabetes medicines, might be raising your risk

Diet and exercise

There is no special diet that cures a UTI, but staying well hydrated is the single most helpful habit. Water is best; some people find that cutting back on caffeine and alcohol eases bladder irritation. Cranberry products are often mentioned, and the evidence is mixed — they are not a treatment for an infection and are not suitable for everyone, so ask your clinician or pharmacist before trying them. Gentle movement, like walking, is fine and can help you feel better. There is no need to avoid exercise unless you feel unwell.

Mental health and emotional wellbeing

Repeated infections or pain when peeing can be tiring, upsetting and sometimes embarrassing, and they can affect sleep, work, sex and mood. Those feelings are completely understandable and worth mentioning to your clinician — they are part of your health, not a side issue. If you ever feel overwhelmed or hopeless, please reach out to a crisis support line in your country, speak to your doctor, or call your local emergency number if you are in danger. You deserve support, and help is available.

Prevention

You cannot prevent every UTI, but you can lower your chances. Drinking enough fluid, not holding on, treating constipation, and peeing after sex all help. If you get infections often, your clinician can discuss other options, such as reviewing your contraception or, for some women after menopause, a local treatment that reduces irritation. Some people are offered a low-dose preventive antibiotic plan — this is used carefully and only when other steps have not worked, because it is exactly the kind of situation where using fewer antibiotics matters.

Vaccines

There is no routine vaccine available to prevent urinary tract infections at present. Researchers are working on vaccines and other preventive treatments, so this may change in the future. Ask your clinician if you would like to know about current options.

Screening programmes

There is no routine screening programme for urinary tract infections. Testing is done when you have symptoms. Pregnant women are usually offered a urine test early in pregnancy, because a UTI without symptoms can still need treatment at that time.

Complications

If left untreated

• The infection may spread from the bladder to the kidney, causing a kidney infection with fever and back pain — this needs prompt treatment
• Rarely, a kidney infection can spread into the bloodstream, which is a serious condition needing hospital care
• In pregnancy, untreated infection is linked to a higher chance of premature birth and of the baby being born small
• In children, repeated infections can, in a small number of cases, be linked to kidney scarring
• In men, the infection can spread to the prostate or testicles

Long-term outlook

For most people, a urinary tract infection is short-lived and settles well, with or without antibiotics. The move towards shorter and more careful antibiotic use is good news: it means treatment is being tailored to you rather than given in a one-size-fits-all way, and it helps keep antibiotics working for the future. If you get infections often, there is real support available — your clinician can look for underlying causes and build a plan with you. Most people find a routine that keeps infections manageable.
