Ulcerative colitis is a form of inflammatory bowel disease (IBD) that primarily affects the digestive tract, but it can affect other parts of the body as well. It can cause symptoms such as bloody diarrhea, abdominal pain, and an urgent need to empty the intestines. Symptoms can go through periods of remission and active disease.
Symptoms can differ from person to person, which can make diagnosis difficult. There are several medications that can treat ulcerative colitis.
