The average patient with ulcerative colitis has a 50% probability of having another flare during the next 2 years; however, patients may have only one flare over 25 years, and others may have almost persistently active disease. A small percentage of patients with ulcerative colitis have a single attack and no recurrence. Typically, remissions and exacerbations are characteristic of this disease, with acute attacks lasting weeks to months.
