Does uncomplicated diverticular disease produce symptoms?

A questionnaire dealing with bowel symptoms was administered to 97 outpatients referred for air-contrast barium enema. Subsequently, the barium enema was interpreted by a radiologist who did not know the results of the questionnaire. Forty-nine had normal x-rays, and 27 had uncomplicated diverticular disease. Weight loss, rectal bleeding, abdominal pain, and pain at night were as common in those with a normal examination as in those with diverticula. Symptoms of colon dysfunction included abdominal pain relieved by defecation, altered stool frequency and consistency with pain onset, abdominal distension, feeling of incomplete evacuation after defecation, and mucus in the stool. These were equally prevalent in both groups. Therefore, no symptoms could be ascribed to the presence of diverticula.
