Teenager's Sex Triggered Severe Urinary Infections That Ended Her Dating Life

Hannah Evans was eighteen and deep in her first serious relationship when painful urinary tract infections began to take over her life. She says almost every time she was intimate with her partner, the same debilitating symptoms would follow – an overwhelming need to empty her bladder and a burning pain so severe that, when she did, it felt like passing razor blades. Before long, the infections were so frequent that Hannah barely seemed to recover from one before the symptoms returned. Sex became such a reliable trigger that she began to dread it and, eventually, largely avoided it altogether. I was in so much pain that I felt constantly anxious when I was away from my flat, says Hannah, now twenty-seven and living in Southampton. When I went to the toilet, it felt like it was on fire.

Hannah had suffered occasional UTIs since childhood, but says it was only after starting university and becoming sexually active that they became a real problem. At its worst, she says, she was developing symptoms at least once a month. The constant need to find a bathroom began dictating where she went and what she did. But perhaps the greatest toll was on her relationship. Sex had become so closely associated with the pain that followed that Hannah began to dread it. It wasn't an enjoyable thing for me, she says. My partner at the time was lovely and he never made me feel guilty about it, but of course I did. At that age, it's your first relationship and you want to be able to have sex. Eventually, the couple largely stopped having sex altogether.

Today, though, Hannah is virtually UTI-free – and enjoys a healthy intimate life. She credits this transformation not to a new drug or medical treatment, but to a radical overhaul of her diet, exercise and lifestyle. So could the changes she made really have helped – and could they offer hope to other women plagued by recurrent infections? UTIs occur when bacteria enter the urinary tract, which includes the bladder, urethra and kidneys. They are particularly common in women because the urethra is shorter than in men, making it easier for bacteria to reach the bladder. Around one in ten women experience a UTI each year, and women account for about four in every five cases. Sex can be a trigger because the activity can move bacteria towards and into the urethra.

Typical symptoms include burning or pain while urinating, needing to urinate more frequently or urgently, cloudy urine and pain in the lower abdomen. More serious infections can cause fever, chills and pain in the back or side and may require urgent treatment. For years, Hannah says, she repeatedly sought help from her GP and was prescribed countless courses of antibiotics. For most women with a straightforward bacterial UTI, this is the standard treatment – and it usually works. Depending on the drug used, studies suggest antibiotics successfully clear the infection in roughly eighty to ninety-five per cent of cases. The problem is that successfully treating one infection does not necessarily stop another from developing. Around one in four women who suffer a UTI will experience another within six months.

When a patient suffers from two urinary tract infections within six months or three in a year, doctors label it recurrent UTI. Simply handing out another short course of antibiotics every time symptoms flare is no longer enough. For women with clear triggers like sex, dehydration, or holding it too long, a single preventive antibiotic dose taken around the time of intercourse can help.

Hannah saw her infections gradually become less severe and stop coming as often after tweaking her diet and exercise routine. Those dealing with frequent infections might instead get offered a daily low-dose antibiotic for several months. Another option is methenamine hippurate, a urinary antiseptic that works in some patients to keep infections away. These methods can slash the number of attacks while treatment goes on. But they are not a permanent fix. Infections often return once preventive care stops, and using antibiotics again and again lets bacteria learn to resist the drugs.

The cycle persisted for Hannah until late 2018, when she was desperate for something new. Her mother suggested she see a naturopath, a practitioner of complementary medicine, and start sweeping changes at home. She added probiotic foods packed with live bacteria thought to support the body's community of beneficial microbes, the microbiome. She also ate prebiotic foods containing fibre that help those bacteria grow. For a while, she cut out sugar, gluten, and dairy entirely. She started taking supplements and herbal preparations, including high-strength garlic, and changed how she moved her body completely.

Hannah used to think a workout only counted if it left her sweating and exhausted. She traded intense sessions for yoga and long walks outdoors and began practicing breathing exercises. 'I was very much the type of person that thought, "If I'm not sweating, then it doesn't count,"' she says. 'Even if it's an enjoyable workout, if you're pushing yourself to the max all the time then it's stressful for your body.'

Dr Philippa Kaye, a GP and Daily Mail columnist with a special interest in women's health, notes there is some scientific rationale behind the idea that probiotics might help chronic UTIs. 'Probiotic bacteria called Lactobacilli are part of the healthy vaginal flora,' she explains. 'Some studies suggest that probiotics containing these bacteria, particularly when used vaginally rather than taken by mouth, may help reduce recurrent UTIs.' The theory is they create an acidic environment in the vagina which makes it harder for infection-causing bacteria to thrive. However, the evidence that taking probiotics actually prevents recurrent UTIs remains uncertain.

A Cochrane review of nine studies involving 735 people found no statistically significant reduction in recurrent UTIs among those given probiotics compared with placebo. Researchers said the studies were generally small and of poor quality, meaning a benefit could not be ruled out. Dr Kaye also points out it is particularly difficult to know what helped in Hannah's case because she made so many changes at once. 'When you change lots of things at once, it's very hard to know which, if any, made the difference,' she says. 'What we do know is that staying well hydrated can help prevent UTIs.' If Hannah was exercising very intensely and sweating a lot, reducing her exercise might have meant she was less dehydrated, contributing to the improvement. She adds caution about unnecessarily cutting out whole food groups like gluten or dairy. Restrictive diets can mean missing important nutrients, and carbohydrates are an important source of fuel for the body. For Hannah, at least, the changes she made proved transformative.

Over time, the flare-ups grew less severe, then shorter, until they finally faded into infrequent occurrences. The final episode linked to her chronic issues happened in 2023, and as those physical pains receded, something deeper shifted within her too. For the first time in many years, Hannah stopped approaching intimacy with the dread that agony would inevitably follow. This change feels so profound she describes it as rediscovering sex entirely, all over again. I feel like a sixteen-year-old losing my virginity again because I'm actually able to enjoy sex, she says. That concept is so alien to me since for such a long time it was terrifyingly scary. She did develop an acute UTI again just three weeks back, but this time she did not experience the same spiral of persistent symptoms that once consumed her. Her journey ultimately changed the course of her career path completely. Hannah now works as an intimate-health naturopath, advising other women who struggle with recurrent urinary problems every single day. She argues that women whose standard urine cultures repeatedly come back negative should never simply dismiss their persistent symptoms without question. However, urinary symptoms can stem from a number of causes, and experts advise that persistent or recurring issues must be medically assessed rather than assumed to be an infection alone. For Hannah, simply reaching the point where a UTI no longer dominates her thoughts has been truly transformative for her mental state. I'm no longer scared if I get a UTI, she says. I know what to do, I can deal with it and then move on with my life.
