Colonic diverticular bleeding. Have we identified the risk factors for massive bleeding yet?

As we know, the frequency of diverticular disease (DD) increases according to age, being less than 5% in patients under 40 years of age and up to 60% after 80 years of age. The most common distribution of diverticula is in the left colon, except for the Asian population, where diverticular disease of the right colon is more frequent.
