Ulcerative Colitis (UC) is a disease where the large intestine or bowel (colon) mucosal lining develops chronic inflammation. It affects only the colon and is associated with formation of ulcers. In some cases, only the rectum or lowest most end of the colon is involved and this is called ulcerative proctitis.
A long-term complication of UC is the development of colon cancer. This risk is higher in patients where the entire colon is diseased and in patients who have suffered UC for longer period of time. For early detection of colon cancer, you may be recommended to undergo screening colonoscopy.
In our local Singapore population, UC is uncommon and occurs in 6 out of 100,000 individuals.
