Will a UTI go away on its own?

Bladder infections are a common health issue, particularly for women, and can recur with frustrating frequency. We asked a urologist whether it's safe to let a urinary tract infection 'run its course', or if antibiotics are always the best treatment.

Around will develop at least one urinary tract infection (UTI) in their lifetime, and people with diabetes and men with enlarged prostate glands are also at risk. Burning and stinging on urination, and feeling achy, sick and tired are the common symptoms of bladder infections, and can make life a misery for those who suffer frequent UTI infections.

show that Escherichia coli (E. coli) is the organism that causes UTIs in the majority of patients, and most infections are caused by bacteria from the bowel getting into the bladder. This is why women are more susceptible, as the anus is so close to the urethra (opening to the urinary tract).

To reduce the risk of infection, wiping from front-to-back after a bowel movement, maintaining personal hygiene, staying hydrated, and using a pH-balanced lubricant during sex (to prevent skin irritation) or topical oestrogen cream following the menopause (to reduce vaginal dryness) may be useful. But self-care tips aren't always enough to prevent UTIs.

Wait it out?

Cystitis (inflammation of the bladder) is a common type of UTI, particularly in women, and is not usually a cause for serious concern.

"It's certainly true that a substantial number of cases of cystitis do clear up with fluids plus painkillers and many patients do manage their condition this way," says , a member of the medical panel and a consultant urologist with Mid Yorkshire Hospitals NHS Trust.

The include fluid and painkillers in self-care for simple bladder infections with no signs of serious infection such as pyelonephritis (kidney infection) or sepsis. They also suggest that in some situations patients should have 'back-up' antibiotics to be taken if symptoms worsen or after 48 hours if symptoms are not settling. They leave open the option of giving a prescription to some women immediately. should have a urine sample sent to the lab for culture and should be offered antibiotics to take straightaway.

Your pharmacist can advise on interim options to control symptoms while you wait for them to resolve. For instance, they can provide sachets which alkalinise the urine, relieving burning and the desire to pass water.

The risks of leaving a UTI untreated

"There was a suggestion in a small in 2010 that using just painkillers may be no worse than antibiotics," adds Ali. "But a more extensive study by the refuted this and showed that women who did not take antibiotics had a significantly higher total burden of symptoms, and more cases of pyelonephritis - a severe infection of the kidney which can require hospital admission and can lead to sepsis."

Similar results to the German trial were seen in a in 2017 and a recent one in 2018. Both showed that avoiding antibiotics was an inferior approach to treating UTIs. While many women will get over the infection without antibiotics, a proportion will experience severe complications.

"Although substantial numbers of women recovered without antibiotics, between 4-5% of the women not treated with antibiotics went on to develop pyelonephritis," explains Ali. "The authors of the Norwegian paper stated that they could not recommend ibuprofen alone as initial treatment for women with uncomplicated UTIs."

When do you need antibiotics?

In its for UK healthcare, the Scottish Intercollegiate Guidelines Network recommends antibiotic treatment for otherwise healthy women, under 65, who have three or more symptoms of UTI.

Potential symptoms of UTI are listed as follows: pain passing urine (dysuria), frequency of urination, bladder pain, urgency, passing lots of urine (polyuria), and passing blood in the urine (haematuria).

"The guidelines recommend using dipstick tests to guide treatment decisions in otherwise healthy women under 65 years of age presenting with mild or more than two symptoms of UTI," comments Ali. "Put simply, if symptoms are severe, urine testing is not required before initiating treatment."

The best course of action

For most sufferers, Ali advises the best course of action is to increase fluid intake, take appropriate pain relief and speak with a healthcare professional for further assessment of symptoms.

If symptoms persist for more than two days - or include a fever, loin pain and/or nausea and vomiting - it is important to see your GP for advice on whether antibiotics are required. It's also important to go back if you've been started on antibiotics and symptoms do not improve within 48 hours.

"While some of the over-the-counter treatments may provide symptomatic relief, the 2018 NICE UTI guidelines state that there is no evidence found for cranberry products or urine alkalinising agents to treat UTI," he adds. "However, there's a . And grapefruit seed extract and oil of oregano have also been found to be beneficial."

A UTI, or something else?

There can be considerable overlap between the symptoms for UTI and sexually transmitted infections (STIs) such as chlamydia and gonorrhoea. Bacterial vaginosis, vaginal thrush, vulvodynia, lichen sclerosus, endometriosis, bladder cancer and overactive bladder may also cause similar symptoms. Antibiotic use may also trigger vaginal thrush in some women and require additional treatment.

"Recent unprotected sexual intercourse, discharge from the urethra and pain within the pelvic area or sexual organs would increase the likelihood of an STI," says Ali. "Again, an assessment by an appropriate healthcare professional would be advised and various swabs or urine tests may be required."

Interstitial cystitis (IC), also known as painful bladder syndrome, may also be a cause of recurrent bladder symptoms. IC is a chronic, non-infectious condition of the urinary bladder that causes frequency and urgency of urination and significant pelvic pain that worsens as the bladder fills up. IC is a difficult diagnosis to make and requires tests and input from a urologist. If you think you may have IC, visit your GP, and contact the and for advice and support.
