Diverticulosis is recognized as the most common cause of intrinsic lower gastrointestinal bleeding in adults. This condition involves the formation of small pouches (diverticula) in the walls of the colon, which can become inflamed or may bleed due to the structure of the blood vessels that feed them. When these pouches rupture or become eroded, they can cause significant bleeding that is often detected as rectal blood or in the stool.

The prevalence of diverticulosis increases with age, making it particularly prominent in the adult population. Many individuals remain asymptomatic until a complication such as bleeding occurs, at which point they may require medical evaluation. Overall, diverticulosis accounts for a large percentage of lower gastrointestinal bleeding presentations in clinical settings, thereby establishing its role as the most common intrinsic cause in adults.
