- A diverticulum is when the inner lining of the large bowel (colon) is pushed out through weak spots in the muscle causing a pouch or sac. Diverticulosis is the presence of diverticula (plural), saclike protrusions of the wall of the large bowel.
- While most patients with diverticulosis are asymptomatic, about 25% will develop symptoms, and about 5% will develop an episode of acute diverticulitis (inflammation of diverticula). (Strate et al. 2015; Tursi 2012)
- It is estimated that over 130,000 Canadians have diverticular disease. (Canadian Digestive Health Foundation 2009)
- The prevalence of diverticular disease increases markedly with age. Among Canadians over age 80, about half develop the disease. (Canadian Digestive Health Foundation 2009)
- Every year, more than 400 Canadians die due to complications associated with diverticular disease. (Canadian Digestive Health Foundation 2009)
- Each year 3,309 Canadians require life-saving surgical intervention to treat their diverticular disease. (Canadian Digestive Health Foundation 2009)
- Diverticular disease incurs direct costs of $88.6 million per year in Canada. (Canadian Digestive Health Foundation 2009)
