Ulcerative colitis (UC) is a type of severe, chronic
inflammatory bowel disease
(IBD), which causes:
- Inflammation in the lining of the colon and rectum
- Ulcers in the lining of the colon and rectum
- Bleeding in the lining of the colon and rectum

The exact cause is unknown. A virus or bacteria may cause the immune system to overreact and damage the colon and rectum.
Having a family member with IBD (includes UC and
Crohn's disease) may increase your risk of developing UC.
UC may cause:
Intestinal complications of UC may include:
- Fistula—abnormal passageway between 2 bodily structures
- Excess bleeding
- Toxic megacolon—a potentially life-threatening condition when the colon severely expands, which may result in reduced blood flow
Other complications of UC may include:

- Steroid anti-inflammatory medications
- Immune modifiers
- Biological agents
partial or complete removal of the colon. This may be necessary for:
- An emergency, such as a perforation, excessive bleeding, or life-threatening infection
- Long-term disease that does not respond to medications or other treatment
- Colon cancer—includes confirmed diagnosis or suspicious tissue on examination
- Lack of growth because of nutritional deficiencies (in children)
Surgery for UC is curative and reduces the risk of colon cancer.
Fecal transplantation may be used to treat UC.
There are no current guidelines for preventing UC.
