Colitis is a chronic disease in which the colon gets inflamed. It may be caused either due to some infections (ulcerative colitis), deprived supply of blood (ischemic colitis) or an autoimmune disease. Symptoms of the disease include pain in abdomen, diarrhea (sometimes bloody diarrhea) and fever. Treatment of colitis involves methods that can help reduce the inflammation. Hence, anti-inflammatory drugs are mainly recommended. In severe cases, when drug therapy fails, surgery is the only option for treatment.
