Inflammation of the pockets found in the colon and large intestine. Symptoms may include abdominal pain, fever and rectal bleeding. Typically, this disease develops from diverticulosis. This occurs when the diverticula that formed during diverticulosis have become inflamed. As with diverticulosis, symptoms can include acute lower left abdominal pain, nausea, constipation, and diarrhea. One cause could be the elevated levels of colonic pressure at the sigmoid colon, the smallest portion of the colon. Severity of the rectal bleeding and subsequent damage can be ascertained via a sigmoidoscopy.
