Why do UTIs become more
common after menopause?
Urinary tract infections (UTIs) become more common during the stages of menopause.
Vaginal dryness, bladder symptoms, discomfort during sex and recurrent urinary tract infections are part of a group of symptoms called genitourinary syndrome of menopause, which is caused by changes in hormone levels after the menopause milestone has been reached.
Changes in hormone levels affect the urinary tract and make women more susceptible to infections.
Understanding why UTIs occur and what treatments are available can make a significant difference to intimate comfort and sexual wellbeing together with quality of life.
Why do UTIs increase after menopause?
Oestrogen supports the health of the urinary tract by helping maintain the lining of the bladder and urethra while supporting protective bacteria that help prevent infection. After menopause, the reduction in oestrogen thins urinary tract tissues and shifts the balance of protective vaginal bacteria which allows harmful bacteria to grow more easily.
These changes make urinary tract tissues more fragile and increase the risk of infection especially in women who have a history of infections.
Common UTI symptoms after menopause
UTIs can present differently for women in the postmenopause stage, and symptoms may be less obvious, so even mild changes in urinary symptoms should be checked by a doctor. Common signs include burning or pain when urinating and frequent urges to urinate even when the bladder is not full.
Other indicators include cloudy or strong-smelling urine along with lower abdominal discomfort or pressure and, occasionally, a mild fever.
How to prevent UTIs after menopause
Several strategies can help reduce the risk of UTIs after menopause such as maintaining good hydration by drinking plenty of water to flush bacteria from the urinary tract.
Practising good hygiene by wiping from front to back and avoiding irritants such as harsh soaps is also beneficial.
Women are encouraged to urinate after sexual activity to help remove bacteria from the urethra and may consider local oestrogen treatment such as vaginal creams or tablets to restore healthy tissue and protective bacteria.
Finally, avoiding unnecessary antibiotics is important because overuse can disrupt healthy bacteria and increase the risk of resistant infections.
When to see a doctor
It is important to arrange a postmenopause consultation if you notice painful urination, frequent urges to urinate, blood in the urine or recurrent infections.
This can clarify the cause and prompt treatment can prevent complications such as bladder or kidney infections and provide support for healthy ageing by protecting urinary tract health.
