Diverticular disease is characterized by the presence of diverticula, which are small outpouchings in the lining of the colon. In most cases, diverticulosis is asymptomatic, but some people may experience changes in bowel habits such as constipation or diarrhea and vague abdominal symptoms that in same rare cases can resemble acute appendicitis, in a condition referred to as acute diverticulitis.
