Diverticular disease is a benign colonic condition where small pockets (diverticula) can bulge out of the colon through areas of weakness in its wall. When these diverticula become infected the condition is known as diverticulitis
Diverticular disease is very common. About a third of Australians over the age of 50 would have some diverticular disease, many are unaware of it. Diverticular disease is rare before the age of 30.
Low fibre diet is considered the main risk factor for diverticular disease. Low fibre predisposes to constipation and harder small volume stool which requires more colonic pressure to propel it down stream. High intra-colonic pressure results in “blow outs” of pouches through weakness areas in the colon.
