Your experience with ulcerative colitis (UC) is unique, so doing research and asking questions may help you get the answers you need. Some of the common questions about UC are addressed here to help you have a conversation with your doctor and other specialists, as well as with family, friends, and other people with UC.
UC is a type of inflammatory bowel disease (IBD) in which the inner lining of the rectum and part (or all) of the colon can be affected by inflammation. The cause of UC is unknown. Research points to multiple factors that may play a role, such as your genes, the environment, and how your immune system works.
UC affects men and women equally. It may be comforting to know that you are not alone in dealing with this disease: an estimated 2 out of 1,000 adults in the United States have UC.
UC is most common in North America and Europe. In the US and Europe, people of Jewish descent are 2 to 4 times more likely to have UC than those of other ethnic backgrounds.
