My daughter has Crohns disease, (diagnosed 5 years ago) and lost her large intestine at 11 years of age. Complications, and three surgeries later, she still suffers. UC only affects the large intestine; Crohns affects everything from mouth to anus. Since there are very few support groups for this condition, if anyone on this forum wants to ask questions, or discuss the disease, I will try to help. Yours, Aye. Dave
