Hi everyone. Could anyone explain this to me? I recently had to take a course of antibiotics (cephalexin) following a surgical procedure to avoid a post-op infection. I dreaded it, because I have problems with chronic yeast infecitons. Sure enough, my yeast has acted up. BUT - my ever-increasing problems with almost daily diarrhea, stomach cramps, acid and pain has been very much IMPROVED since the surgery and course of antibiotics. Can anyone identify any cause for this? I can't find anything by Googling. Everything talks about antibiotics CAUSING diarrhea, not helping it. It is very interesting, because probiotics seem to have a bad effect on me, making my diarrhea worse. I was taking more and more of them to help with my stomach, and they were definitely making me worse. When I stopped the probiotics I noticed an improvement. Following the antibiotics, I had the first solid BM I had experienced in over a month. Thank you for any insight you might have!
