I have Diverticulosis not Diverculitis is what the nurse said. Diverculitis is when you have infection, and I don't, just inflammation. I had no problem with the prep for my initial colonoscopy except it was unpleasant. My colon isn't narrowed, it is very stretched out from having previous episodes of constipation building up in my colon expanding my colon. It stretched it like filling a water balloon then when you let it out it's stretched out of shape and floppy. That's how she explained it. And it's also been left with many irritated pouches which should hopefully be ok, but is at a higher risk of peforating my bowel because of the number of them and the severity of the inflammation. She said the damage is already done, and there's probably not much that can be done now to undo it, but they still need to see all my colon because everyone needs a screening for colon cancer, and he also wants to see what if any damage is in the loop and on the other side of my bowelthat he couldn't get to. I didn't understand ANY of this before yesterday, and it's still very new to me, but at least I know it's nothing serious and nothing to worry about.
