Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation in the colon, also called the large intestine. The type of UC symptoms you experience may depend on where inflammation is occuring in the colon.
Doctors have defined four types of UC based on which of those segments of the colon are inflamed. “By definition, ulcerative colitis starts at the very end of the colon, and can extend farther towards the beginning,” says Todd B. Linden, MD, gastroenterologist.
Dr. Linden is a gastroenterologist based in New York City and a clinical instructor in the Department of Medicine at NYU Langone Health.
Dr. Khaitov is a surgeon specializing in colon and rectal surgery at Mount Sinai Hospital.
