Ulcerative colitis is characterised by the inflammation of inner lining of the colon and the rectum. Scientists have identified that some autoimmune response (abnormal response by the immune cells) by these intestinal parts are often associated with the development of ulcerative colitis. When the aberrant immune cells get triggered by bacterial or viral infection, the problem starts developing. The inflammation initially begins from the rectum and spreads to the colon. A few symptoms of ulcerative colitis are: sudden bowel movement, abdominal pain, fever, dehydration and weight loss. Scientists have found that in about 20% of the cases, this disease gets transmitted through genes. Ulcerative colitis is non curable disease but the severity can be controlled with the help of medicinal therapy along with some dietary and lifestyle modifications.
