Recurrent urinary tract infections (UTIs) pose a significant challenge for many older women, with treatment often complicated by underlying health factors. Women over the age of 50 are particularly vulnerable due to physiological changes following menopause, which can contribute to the frequency of infections.

The proximity of the female bladder to the vagina and rectum facilitates the transfer of bacteria, and the decline of oestrogen levels after menopause weakens the bladder tissue’s natural defenses against infection. Medical professionals commonly recommend the use of vaginal oestrogen therapy, prescribed by a general practitioner, to help restore the protective environment and reduce the incidence of recurring UTIs.

Additional factors contributing to recurrent infections include constipation and pelvic organ prolapse. Constipation can cause stool buildup that impedes complete bladder emptying, while prolapse—the displacement of the bladder or womb—can similarly affect bladder function. Both conditions are prevalent among older women and should be evaluated when addressing recurrent infections.

Experts advise maintaining adequate hydration, recommending approximately 1.5 liters of water per day to help flush bacteria from the bladder. Avoidance of irritants such as soaps or bath products in intimate areas is also advised as these can exacerbate symptoms.

Several treatment avenues exist for managing recurrent UTIs. One option includes the supplement D-mannose, which may reduce the frequency of infections for some women, although its effectiveness varies. Another approach is the use of prophylactic antibiotics administered nightly under medical supervision. For patients who cannot tolerate or do not respond to these antibiotics, methenamine hippurate—marketed as Hiprex—may be prescribed. This medication functions as an antiseptic, limiting bacterial growth within the bladder.

Due to the potential severity of symptoms, health professionals recommend that older women experiencing repeated UTIs undergo an ultrasound scan to examine the ovaries and bladder. While infections are common and generally manageable, persistent symptoms could, in rare cases, indicate underlying malignancies requiring further investigation.

Overall, addressing recurrent UTIs in older women involves a multifaceted approach, including hormonal treatment, lifestyle adjustments, and careful medical monitoring to both prevent infection and rule out more serious conditions.
