Ulcerative Colitis (UC) is another form of inflammatory bowel disease (IBS). Unlike Crohn’s, which can affect any part of the digestive tract, UC only affects the colon and rectum. This disease causes ulcers in the lining of the large intestine, but can affect the entire colon. The cause is unknown, however, experts think it may be caused by the immune system overreacting to normal bacteria in the digestive tract, viruses, or other kinds of bacteria. Hereditary factors also play a roll as you are more likely to get UC if other people in your family have it. The top three indications of Ulcerative Colitis are: Stomach ache or cramps, diarrhea, and/or rectal bleeding. Unfortunately the disease can also lead to liver disease, joint pain, and eye problems. In most cases patients experience bouts of remission, the symptoms may subside for years. However, roughly 5-10% of sufferers have symptoms all the time.
