My doctor is having me evaluated for ulcerative colitis. I have had diarrhea for over a week now, lost more than ten pounds in less than seven days, have been able to eat four pieces of toast and a small bowl of cottage cheese in the last 72 hours, feel tired, nauseated, and just generally awful. Googling is just making me more worried. Anyone have UC? Does this sound familiar to you? How long will it last?
