General Discussion

Ulcerative colitis is an inflammatory bowel disease (IBD) of unknown cause. It is characterized by chronic inflammation and ulceration of the lining of the major portion of the large intestine (colon). In most affected individuals, the lowest region of the large intestine, known as the rectum, is initially affected. As the disease progresses, some or all, of the colon may become involved. Although associated symptoms and findings usually become apparent during adolescence or young adulthood, some individuals may experience an initial episode between ages 50 to 70. In other cases, symptom onset may occur as early as the first year of life.

Ulcerative colitis is usually a chronic disease with repeated episodes of symptoms and remission (relapsing-remitting). However, some affected individuals may have few episodes, whereas others may have severe, continuous symptoms. During an episode, affected individuals may experience attacks of watery diarrhea that may contain pus, blood, and/or mucus; abdominal pain; fever and chills; weight loss; and/or other symptoms and findings. In severe cases, individuals may be at risk for certain serious complications.

For example, severe inflammation and ulceration may result in thinning of the wall of the colon, causing tearing (perforation) of the colon and potentially life-threatening complications. In addition, in some cases, individuals with the disorder may eventually develop more generalized (systemic) symptoms, such as certain inflammatory skin or eye conditions; inflammation, pain, and swelling of certain joints (arthritis); chronic inflammation of the liver (chronic active hepatitis); and/or other findings.

The specific underlying cause of ulcerative colitis is unknown. However, genetic, immunologic, infectious, and/or psychologic factors are thought to play some causative role.
