I am 74 and for a few years had suffered from repeated UTI's. Usually about 6 per year. I got a bidet about a year ago, use it each and every time I go to the toilet and never had a UTI since.
I have encouraged my Doc to tell all of her patients with UTI's to get a bidet. I had read it on the internet somewhere that the majority of UTI's are because of E.coli.

Just an update on my Mom. In late 2023 she was placed on the vaginal cream (daily) and the low dose antibiotic (daily). She has only had one UTI since. She had 7 in 2023, 1 in early 2024 and none since then. A true blessing.
