4 The natural history of ulcerative colitis

Abstract

The majority of patients with ulcerative colitis (UC) will run a typical chronic, relapsing course. The proportion with chronic, continuous symptoms diminishes with time. The greatest impact of the disease is in the first few years after diagnosis, especially in patients with extensive or severe colitis. After this time, the likelihood of requiring surgery declines rapidly, and survival is no different from that of the general population. The long-term course can be best predicted by the course in the preceding period. Most patients are able to lead an essentially normal lifestyle, at work and at home, with either medical or surgical treatment. Awareness of how the patient feels the disease affects his or her life is important. Educating the patient about their illness will also help in management.
