I was diagnosed about 6 years ago with left side UC. I just had a Colonoscope today and my GI said I really have diverticular colitis. He said that recently there is a realization that some patients diagnosed with UC really have diverticular colitis. He said that this is not an autoimmune disease and could be caused by inadequate blood flow to a portion of the colon. He said that the treatment is the same as UC.
Has anyone heard of diverticular colitis? When speaking to the doctor, I was still groggy having just come out of anesthesia and did not ask questions.
