@fmsvi did you even read my post? I’ve had MC for more than 35 years. 35 years ago most GI’s didn’t know what it was and/or how to diagnose it. The research that discovered it was in the late 80’s, maybe five years before I developed it. What was strange was that I developed it at an early age. I eventually did find out what it was through a colonoscopy where a GI did took several biopsies, but this was years later.

Ulcerative colitis definitely shows up in a colonoscopy.
