I know what it is. I was in the hospital a few years ago. They told me I had diverticulitis in the bowels but it was not inflamed . But I often wonder how they found out. They did not do a colonoscopy? Here is the report:
There is colonic diverticulosis without evidence of an active inflammatory process. The bowl is normal in caliber,
No free air or free fluid. Rectum and bladder appears normal.
