Diverticular disease is a disease where pouch-like structures, called diverticula, develop through points of weakness in the wall of your large intestine. Diverticular disease is found in equal proportions in both male and female populations. It is very common and up to 60% of people over the age of 60 have diverticula in their large intestine. Although, the exact etiology of the disease is unknown, obesity, and a sedentary lifestyle are risk factors for the disease. Whereas, a diet rich in seeds doesn’t appear to be a risk factor for the disease. It can be asymptomatic if uncomplicated, or presented with fever, pain or bleeding from the rectum, (the lower part of the large intestine), when complicated. Treatment consists of antibiotics if an inflammation is present and in rare cases surgery if the disease is seriously complicated. Colonoscopy procedure is indicated after an episode of diverticular disease to screen for possible malignancy that may present as complicated diverticular disease.
