We never knew it until a couple of Doctors filled us in and we did some online research. My Dad had open heart surgery 2 months ago and his physical health is good other than occasional UTIs, but his mind keeps him from doing what he needs to do to rehab.
It’s been quite maddening to watch him just give up on life when there is nothing really wrong with him.
Some UTIs require antibiotics to clear them up, but you may try giving him a daily dose of d-mannose which is what makes cranberry work so well for treating UTI. I really like the Now brand cranberry with uva ursi. Maybe it would keep them from recurring.
