Hello Thanks for writing to us with your health concern. Recurrent infections in this age group are most often due to atrophic vaginitis. This is friability and thinning of the local vaginal mucosa, due to estrogen deficiency in the tissues. You should wash thoroughly and pass urine after every act of intercourse. Also do not rub, scrub, itch , scratch or handle the area excessively. Just clean with warm water and pat dry gently. Also, do not use any soaps, gels, cleansers or douches. Drink lots of water as a routine - 5 litres of fluids daily. Deworm yourself, as it could be a primary anal infection. Untreated hypothryoidism also predisposes to infection. Get your vitamin D levels checked, as vitamin D deficiency in itself predisposes to recurrent UTIs. Your blood sugars should be tested to rule out diabetes. A renal ultrasound scan and complete urine analysis should be done to detect any stones / abnormalities in the urinary tract which predispose to recurrent infections. Make sure that proper culture based antibiotics have been taken, to avoid risking lingering untreated infection. Also, empty your bladder more frequently ( avoid holding urine for prolonged period ) and avoid using public toilets. Local estrogen gels can help in reducing atrophic vaginitis. Use lubricants during intercourse. IN general, maintain an ideal BMI and exercise regularly and eat sensibly to maintain good immunity to fight infections. All the best.
