I am a 68 year old female of normal weight, active and w/o new health issues. In January my bowel movements changed overnight; there has been no change in diet or hydration, activity level, meds (only Rx is beta blocker for a PSVT that appeared 3 years ago). I went from having normal looking stools to passing small “stones” (Bristol scale image 1). I went to see gastroenterologist who said, “Let’s start with colonoscopy.” That sounded reasonable as it was almost ten years since the last one which was 100% normal. Well, so was this one. I am almost two weeks past thar test, and my stools went right back to small stones. I poop on a regular time schedule, and there is no-strain to pass the stools. I am scheduling a follow up with the same doctor, but I am curious if any one has lived through this. Probiotics change nothing. Thank you.
