A burning sensation when you urinate. The constant need to go but only passing a small amount. A nagging discomfort in the lower abdomen. These symptoms are immediately recognisable to the large number of women who have experienced a urinary tract infection, or UTI.
UTIs are among the most common bacterial infections in women. Research suggests that approximately one in two women will develop a UTI at some point in their lifetime, and many women experience recurrent infections across their reproductive years. Despite this, many women feel embarrassed about UTI symptoms, delay seeking care, or try to manage infections at home in ways that are not effective.
This guide explains what a UTI is, how to recognise one, what causes it, what can be done about it, and when symptoms require prompt medical attention. The guide also addresses what UTI symptoms are not, since burning or discomfort during urination does not automatically mean a UTI.
A urinary tract infection is an infection that occurs anywhere along the urinary tract, which includes the urethra (the tube through which urine exits the body), the bladder, the ureters (the tubes connecting the kidneys to the bladder), and the kidneys themselves.
The most common type of UTI affects the lower urinary tract, specifically the urethra and bladder. This is called cystitis when the bladder is involved and urethritis when the urethra is primarily affected.
When infection spreads to the upper urinary tract, particularly the kidneys, this is called pyelonephritis and is a more serious condition requiring prompt medical attention.
Most UTIs are caused by bacteria, most commonly Escherichia coli (E. coli), a type of bacteria that normally lives in the intestines. When bacteria enter the urethra and travel into the bladder, they can multiply and cause infection.
Women develop UTIs significantly more frequently than men, and anatomy is the primary reason.
In women, the urethra is much shorter than in men, approximately 3 to 5 centimetres compared to 20 centimetres in men. This shorter distance means bacteria from outside the body have a much shorter journey to reach the bladder. The opening of the urethra is also located close to the vaginal opening and the anus, areas where bacteria naturally reside. This proximity makes it easier for bacteria to enter the urethra.
The shorter urethra also means that bacteria that do enter the urinary tract do not have to travel as far or multiply as much before they can reach the bladder and cause symptoms.
Beyond anatomy, several other factors related to women's lives and biology further increase risk across different life stages, which are discussed in the risk factors section.
UTI symptoms can vary between women and depending on which part of the urinary tract is affected. The following are the most commonly reported symptoms.
Burning or pain during urination: This is the most recognised UTI symptom. The burning sensation occurs because the infected, inflamed lining of the urethra and bladder is irritated by urine passing through it. The pain or burning typically occurs during urination rather than before or after.
Frequent urination: A UTI inflames and irritates the bladder, making it feel as though it needs to be emptied even when it contains only a small amount of urine. Women with UTIs often find themselves going to the toilet much more frequently than usual.
Urgent need to urinate: An intense, sudden urge to urinate that may be difficult to defer, even when the bladder is not full.
Passing only small amounts of urine: Despite the urgent need to go, only small amounts of urine are produced. This is because the inflamed bladder signals urgency even when it is not full.
Lower abdominal discomfort or pressure: A dull ache, pressure, or discomfort in the lower abdomen, above the pubic bone, is common in bladder infections.
Cloudy urine: Urine that appears cloudy rather than clear may indicate the presence of white blood cells or bacteria, both of which the body sends to fight the infection.
Strong or unpleasant smelling urine: Urine may have a stronger or more unpleasant odour than usual during a UTI.
Blood in the urine (haematuria): Urine may appear pink, red, or brown due to the presence of blood. This occurs because the inflamed urinary tract lining bleeds into the urine. Blood in the urine always warrants medical evaluation, and when accompanied by other UTI symptoms, it requires prompt assessment.
It is important to note that symptoms vary between individuals. Some women with confirmed UTIs have only one or two of these symptoms. Others have several. And some women, particularly older women and those with certain health conditions, may have a UTI with few or no obvious urinary symptoms.
Not every change in urinary habits means a UTI is present. The symptoms above can also be caused by other conditions, which is addressed later in this guide.
Teenage girls can develop UTIs just as adult women can. The same anatomical reasons that make women generally more susceptible to UTIs apply from the time menstruation begins and through the teenage years.
In teenage girls, UTI symptoms are essentially the same as in adult women, but teenagers may be less likely to recognise what the symptoms mean, more likely to feel embarrassed about discussing urinary symptoms, and less likely to know when and how to seek help.
Any teenage girl experiencing burning during urination, significantly more frequent urination than usual, an urgent need to urinate, lower abdominal discomfort, or blood in the urine should be encouraged to speak with a parent, guardian, school health professional, or doctor. These symptoms are not embarrassing. They are medical symptoms that deserve appropriate care.
A UTI does not mean anything negative about hygiene, behaviour, or character. It is a bacterial infection that is extremely common and very treatable.
Most UTIs occur when bacteria from outside the body enter the urethra and travel to the bladder, where they multiply and cause infection.
The most common cause is Escherichia coli (E. coli), responsible for approximately 80 to 85 percent of uncomplicated UTIs. E. coli normally lives in the intestines and around the anal and vaginal area without causing any problem. When it enters the urethra and bladder, however, it can cause infection.
Other bacteria less commonly responsible for UTIs include Staphylococcus saprophyticus, Klebsiella, and various other organisms.
It is important to understand that developing a UTI does not mean a woman is unclean or that she has done something wrong. Bacteria that cause UTIs are normal residents of the body in their usual locations. Their entry into the urinary tract can happen easily given the anatomy of the female urinary and reproductive systems, regardless of hygiene practices.
While any woman can develop a UTI, certain factors increase the likelihood of infection.
Previous UTIs: Women who have had one UTI are significantly more likely to develop another. Recurrent UTIs, defined as two or more in six months or three or more in a year, are a recognised clinical pattern that warrants specific investigation and management.
Sexual activity: Sexual intercourse can introduce bacteria into the urethra. This is one of the most consistent risk factors for UTI in sexually active women, leading to the commonly known "honeymoon cystitis" pattern of UTIs associated with new or increased sexual activity. Urinating after intercourse reduces this risk for many women.
Pregnancy: Hormonal changes during pregnancy relax the muscles of the urinary tract, reducing the speed at which urine flows through it. This slower flow allows bacteria more time to multiply. Asymptomatic bacteriuria (bacteria in the urine without symptoms) is screened for and treated during pregnancy because untreated, it carries an increased risk of kidney infection, which can affect pregnancy outcomes.
Menopause: After menopause, declining oestrogen levels lead to changes in the tissues of the urinary tract, including thinning of the urethral and bladder tissues and changes in the vaginal microbiome that reduce natural protection against UTI-causing bacteria. Postmenopausal women have significantly higher UTI rates than premenopausal women.
Urinary tract abnormalities: Structural abnormalities of the urinary tract that affect the flow of urine or the complete emptying of the bladder increase UTI risk.
Difficulty completely emptying the bladder: Urine that remains in the bladder provides an environment where bacteria can multiply. Conditions that prevent complete bladder emptying, including certain neurological conditions, increase UTI risk.
Certain types of contraception: Diaphragms and spermicide-containing contraceptives have been associated with increased UTI risk in some studies, potentially because they affect the vaginal microbiome.
Certain medical conditions: Diabetes (which affects immune function and creates a glucose-rich environment favourable to bacterial growth), immunosuppression from any cause, and kidney stones all increase UTI risk.
Catheter use: Women who use urinary catheters have significantly elevated UTI risk.
While UTIs cannot always be prevented, several simple daily habits reduce risk.
Drink enough fluids for your body's needs. Adequate fluid intake produces more urine, which flushes bacteria from the urinary tract before they can multiply to infection levels. The specific amount varies by body size, activity level, and climate, but consistently pale yellow urine is a reasonable indicator of adequate hydration.
Do not regularly hold your urine for long periods. Urinating when you feel the need rather than delaying prevents the accumulation of bacteria in the bladder. Consistently suppressing the urge to urinate allows bacteria more time to multiply.
Wipe from front to back after using the toilet. Always wipe from the front (urethra and vaginal area) toward the back (anus), never from back to front. This prevents faecal bacteria from being transferred to the urethral area.
Urinate after sexual intercourse. Urinating after sex helps flush bacteria that may have been introduced into the urethra during intercourse. This is one of the most consistently recommended and effective UTI prevention strategies for sexually active women.
Keep the genital area clean without harsh products. Wash the external genital area with warm water. Do not use strongly scented soaps, intimate washes, douches, or sprays in or around the vaginal opening. These disrupt the natural bacterial balance that provides some protection against UTI-causing bacteria.
Wear comfortable, breathable underwear. Cotton underwear allows airflow and prevents the warm, moist environment that encourages bacterial growth. Avoid very tight synthetic underwear for extended periods.
Change out of wet clothing promptly. Wet swimwear or damp workout clothes create conditions that encourage bacterial growth in the genital area.
Cranberry products, including juice and supplements, are frequently recommended as a natural UTI prevention strategy. The rationale is that compounds in cranberries called proanthocyanidins may prevent certain bacteria, particularly E. coli, from adhering to the walls of the urinary tract.
The evidence on cranberry products for UTI prevention is mixed. Some studies show a modest reduction in UTI recurrence in women who use cranberry products regularly. Other studies show no significant benefit. The evidence is not strong enough for cranberry products to be a definitive recommended medical intervention, and results vary between individuals.
The important point for this guide is what cranberry products cannot do. They cannot treat an existing UTI. If bacteria have already established an infection in the urinary tract, cranberry juice will not eliminate the infection. An established bacterial UTI requires antibiotic treatment.
Drinking cranberry juice as part of a generally healthy diet is reasonable and unlikely to cause harm, with the exception of interactions with certain blood-thinning medications such as warfarin. But it should not be relied upon as either a treatment for an existing UTI or a guarantee of prevention.
This is one of the most important questions to address clearly.
Home measures, including drinking more water, resting, and using a warm compress on the lower abdomen, can reduce the discomfort of UTI symptoms. Staying well hydrated may help flush bacteria and reduce symptom severity.
However, home measures do not reliably eliminate a bacterial UTI. If bacteria have established themselves in the urinary tract in sufficient numbers to cause symptoms, the infection typically requires antibiotic treatment to resolve. An untreated UTI that is left to run its course without appropriate treatment can spread to the kidneys, where it becomes a significantly more serious infection.
Several important cautions regarding home management of UTIs:
Do not use leftover antibiotics from a previous prescription to self-treat a UTI. Leftover antibiotics may be the wrong type for the bacteria causing the current infection, may be at an insufficient dose, and contribute to antibiotic resistance. Any antibiotic treatment should be prescribed by a healthcare professional based on assessment of the current infection.
Do not use someone else's prescription antibiotics.
Do not rely on online remedies, supplements, or herbal treatments as a substitute for medical assessment when UTI symptoms are present.
When in doubt, see a doctor. UTIs are very treatable with appropriate antibiotics and the consequences of an untreated or inadequately treated UTI are potentially serious.
Most uncomplicated lower UTIs in otherwise healthy, non-pregnant women are treated with a course of oral antibiotics prescribed by a healthcare professional. Common antibiotic choices depend on local resistance patterns and the specific bacteria identified, and the course is typically three to seven days depending on the antibiotic chosen.
A urine sample (midstream clean-catch urine) may be sent for culture and sensitivity testing, particularly for recurrent UTIs, to identify the specific bacteria causing the infection and confirm which antibiotics will be effective against it.
For women with recurrent UTIs, a healthcare professional may recommend longer-term preventive strategies including low-dose continuous antibiotic prophylaxis, post-intercourse antibiotic prophylaxis, or other evidence-based approaches. These decisions are individualised based on the pattern and frequency of infections.
Phenazopyridine (a urinary analgesic available in some markets) can relieve the pain and burning of UTI symptoms but does not treat the underlying infection. It is a symptomatic comfort measure, not a treatment.
See a healthcare professional if you have urinary symptoms that persist for more than a day or two, are worsening, or are accompanied by any of the following features.
Fever or chills: The presence of fever alongside urinary symptoms can indicate that the infection has spread to the kidneys. Kidney infection (pyelonephritis) is a more serious condition requiring prompt medical attention.
Pain in the back or side (flank pain): Pain in the lower back, particularly pain on one side, located at the level of the kidneys, is a warning sign of upper urinary tract involvement.
Nausea or vomiting: These symptoms alongside urinary symptoms suggest the infection may be more systemic.
Feeling very unwell: A general sense of being significantly unwell, beyond what simple bladder discomfort would explain.
Blood in the urine: Any blood in the urine warrants prompt evaluation.
Symptoms during pregnancy: Any urinary symptoms during pregnancy require prompt evaluation. Untreated UTIs in pregnancy carry risks including preterm labour and kidney infection.
Symptoms that are getting worse rather than better: If symptoms have been present for more than one to two days and are worsening rather than resolving, medical assessment is needed.
Do not delay seeking medical care for these features. Kidney infections, if inadequately treated, can become very serious. Early assessment and appropriate antibiotic treatment produce significantly better outcomes than waiting.
Burning during urination is the symptom most associated with UTI in most people's minds. But burning on urination is not specific to UTI. It can also be caused by several other conditions that require different assessment and treatment.
Vaginal infections: Bacterial vaginosis and vaginal yeast infections can cause burning and irritation around the vaginal and urethral area, sometimes producing burning during urination. Distinguishing these from UTI requires examination and, where needed, testing.
Sexually transmitted infections (STIs): Several STIs, including chlamydia, gonorrhoea, and herpes, can cause urethral inflammation (urethritis) that produces burning during urination. STI-related urethritis often occurs without the frequency and urgency of a typical bladder infection.
Irritation from personal care products: Soaps, intimate washes, scented wipes, bubble baths, and other products applied in or near the vaginal area can irritate the urethra and surrounding tissues, causing burning during urination that is not caused by infection.
Vulvodynia or other vulvar conditions: Chronic vulvar pain conditions can cause burning that is localised to the vaginal and urethral area.
Interstitial cystitis (painful bladder syndrome): A condition causing chronic bladder pain and urinary frequency that is not caused by bacterial infection and does not respond to antibiotics.
This list is not exhaustive, but it illustrates why it is not appropriate to assume that burning during urination automatically means a UTI. If symptoms are persistent, worsening, unusual, or accompanied by other concerning features, proper medical evaluation including urine testing is the appropriate response. A healthcare professional can distinguish between these causes and ensure the right treatment is provided.

If you have urinary symptoms, persistent discomfort, or any of the warning features described in this guide, please seek medical evaluation promptly.
What are the first signs of a UTI?
The earliest symptoms of a UTI often include a burning or stinging sensation during urination, feeling an urgent need to urinate more frequently than usual, and passing only small amounts of urine despite the urge. Lower abdominal discomfort or pressure may also be present. Symptoms can develop quite rapidly, sometimes over the course of a few hours.
Can a UTI go away on its own?
Some very mild urinary symptoms occasionally resolve without treatment. However, a bacterial UTI should not simply be ignored or left untreated, particularly if symptoms persist beyond a day or two, are worsening, or are accompanied by fever, back pain, or blood in the urine. Untreated UTIs can spread to the kidneys. Appropriate medical evaluation ensures the right treatment is given.
Is drinking water enough to cure a UTI?
Drinking adequate water supports hydration and may help flush some bacteria from the urinary tract, which can reduce symptom severity. However, water alone is not a reliable cure for a bacterial UTI that has already established itself. An established bacterial UTI typically requires antibiotic treatment to fully resolve.
Can teenage girls get UTIs?
Yes. UTIs can and do occur in teenage girls and are caused by the same mechanisms as in adult women. Any teenage girl with persistent urinary symptoms should be encouraged to speak to a parent, guardian, or healthcare professional for evaluation and appropriate treatment.
Is a UTI contagious?
A typical bacterial UTI is not considered contagious from person to person. However, some conditions that can cause similar urinary symptoms, particularly certain STIs, can be transmitted between people. This is one of the reasons why proper medical evaluation of urinary symptoms, rather than self-diagnosis, is important.
What should I do if I have burning during urination?
Do not automatically assume it is a UTI, as other conditions can cause similar symptoms. If burning persists for more than a day or two, worsens, or is accompanied by fever, back pain, blood in the urine, or feeling very unwell, seek medical assessment promptly. Providing a urine sample for testing allows a healthcare professional to confirm or rule out bacterial infection and identify the appropriate treatment.
Can I prevent UTIs?
Several habits reduce UTI risk. These include drinking enough fluids daily, urinating when you feel the need rather than holding it, wiping front to back after the toilet, urinating after sexual intercourse, wearing breathable cotton underwear, and avoiding scented intimate products. These measures reduce risk but do not guarantee complete prevention, particularly in women who are prone to recurrent infections.
