    What is the definition of ?

    Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) characterized by the development of ulcers in the lining of the digestive tract, which most often affect the colon and rectum. While ulcerative colitis can occur at any age, it most frequently appears between the ages of 15 and 30, or after the age of 60. There are several types of ulcerative colitis that are categorized by the area of the digestive tract affected by the disease, such as ulcerative proctitis (inflammation of area closest to the rectum), proctosigmoiditis (inflammation of the sigmoid colon and rectum), left-sided colitis (inflammation of descending colon, sigmoid colon, and rectum), pancolitis (inflammation of the entire colon), and a rare form of ulcerative colitis known as acute severe ulcerative colitis (severe inflammation of entire colon). Ulcerative colitis can also affect other areas of the body, causing inflammation of the skin, eyes, liver, joints, and back.
