Hi Thank you for asking HCM. I have gone through your query. Change of normal PH and bacterial flora can be a reason for recurrent urinary infection. In such you can use intimate wash regularly to normalize vaginal bacterial flora and PH. You should also clean your genitals after sexual intercourse. Proper antibiotics for proper duration should be taken when you get infection. Take more plain water daily. Barley water or cranberry juice may help to alkalize urine and prevent you from getting infection. Hope this may help you. Let me know if you have any further queries.
