Symptoms of ulcerative colitis vary among affected individuals. Typical symptoms include abdominal pain, diarrhea, and rectal bleeding. Depending upon the degree of inflammation and the location of the inflammation within the colon, other signs and symptoms can occur. Rectal pain, a sense of urgency in needing to defecate, and tenesmus (ineffective and painful urge to defecate) are symptoms of rectal involvement. Weight loss, fever, night sweats, fatigue, and dehydration are all possible symptoms and signs of ulcerative colitis.
