I've been taking 500mg twice daily, with breakfast and supper for 7+ years. All of a sudden two
years ago I started having chronic diarreah. I had several tests...colonoscopy, endoscopy, SIBO,
thyroid test and more. Everything kept coming back with no signs of bacteria, colitis, crohns and
was diagnosed with IBS-D. At my annual physical my doctor had me stop the metformin for a month.
It's been 2 weeks so far and the culprit seems to be the metformin. My CVS pharmacy changed the
metformin manufacturer about two years ago (smaller pill size). I feel as though I have a new lease on
life but I'm not sure what he may suggest when I go back in two weeks. My A1C was 5.6% but glucose
was a bit high at 122. Has this happened to anyone else? If so, please describe. Thank you!
