My cousin is 40 just found out she has colitis. She's scared, what is the cause. Can it be can ER or can it be something else? .

A serious disease. "colitis" usually refers either to ulcerative colitis or crohn's colitis - inflammatory diseases of the colon. No 'cause' is known. Young people are often affected. Both are serious and require care from a physician who treats these diseases often.. They may be mild or very severe with bleeding, diarrhea and pain. Medicines are effective, .But surgery is required in advance cases. Peter wilk, md.
