No, Myself. Crohn's colitis is caused by Crohn's disease that is only affecting your colon. The ulcers from Crohn's disease can eat through the intestines and start affecting organs close by. The ulcers from ulcerative colitis don't do that. You have ulcers but they don't burrow through the colon. Also, Crohn's disease can affect your entire digestive system whereas ulcerative colitis affects only your colon and rectum.
I was misdiagnosed with ulcerative colitis for 11 years before they discovered it was Crohn's disease that was causing this. Only my colon and rectum were affected so it was called Crohn's colitis.
Foods can exacerbate the condition and I had to eat what I told Sera to help keep it under control. This goes for both ulcerative colitis as well as Crohn's colitis.
