UC effects the large bowel only. My nephew has UC and he has alot of blood and mucus in his stools, whereas I have crohns and I never have blood. I do know that if you have your colon removed you will then be rid of the UC, whereas with the crohns it can effect us from the mouth to the anus. I've also been told that it is rare for a patient with UC to suffer from abscesses, whereas I seem to have enough for two people, lol. It would be nice to be healthy and not have either one.
All the best,
