The Real Reason UTIs Keep Coming Back

Third round of antibiotics this year. Third doctor who said "just drink more cranberry juice." Here's what none of them told me: the reason UTIs spike after 40 has almost nothing to do with hygiene and everything to do with estrogen. As it declines, the tissue thins, the protective bacteria die off, and the pH shifts to something E. coli finds very comfortable. It's not you. It's a plumbing environment that changed on you without warning.
