When I used to get chronic UTIs 3-4x a year I used OC Pyridium. It's the only thing that stopped the pain for me. I agree with using estrogen cream. You don't have to use it in the vagina although it would keep your bladder healthy because the vagina and bladder share the same wall. You can use the local non-systemic estradiol cream the size of a pea in the vulva (outer area) and urethra. That whole area has estrogen receptors. Coconut oil isn't going to stop any vulva, or urethra atrophy (goggle, urogenital atrophy). Lack of estrogen weakens the muscles of your urethra. This makes it easier for bacteria to enter your urethra and move up to your bladder. Estrogen keeps the thinning vulva and urethra at the correct pH. Estrogen helps vulva tissues and urethra stay elastic and moist. Please reconsider. There is a whole host of disabling unpleasant things that can happen with a lack of estrogen in this area. When I started using estrogen around the vulva my UTIs stopped. I am 74 and haven't had a UTI in 13 years or anything that feels like a UTI.
