Colonic diverticulitis is a disease of affluence, particularly prevalent in industrialized countries.
At the origin of diverticular disease, in addition to some genetic predisposition, there is almost always an unbalanced diet, too high in fat and sugar and too low in water and fiber.
Strictly speaking, diverticulosis of the colon is not a real disease but a congenital or acquired abnormality. Only when the diverticula become inflamed, evolving into diverticulitis, does the disease show signs of itself.
