Ulcerative colitis (UC) is one subtype of inflammatory bowel disease (IBD) whose pathogenesis is multifactorial and includes influences from genes, the environment, and the gut microbiome. In UC the inflammatory is limited to the musoca of the colon and rectum. Clinically, the most common manifestation of UC may include bloody diarrhea, abdominal pain. In most severe cases, patients may experience fever, weight loss, anemia, and the intestine can get distended, presenting deep ulceration and possibly intestinal perforation.The long-time duration of the disease increases a colorectal caner risk. UC is associated with a Th2 immune response. Recent genetic analyses have linked genes including interleukin 23 receptor, interleukin 10 and macrophage stimulating 1.
