Which colon is most commonly associated with diverticulosis?

Diverticulosis is a condition characterized by the formation of small pouches, or diverticula, in the walls of the colon. These pouches develop due to increased pressure within the colon, often as a result of a low-fiber diet and the natural aging process. Among the various segments of the colon, the sigmoid colon is the region most commonly affected by diverticulosis.

The sigmoid colon, located at the distal end of the colon, experiences higher levels of intraluminal pressure due to its narrower diameter and the action of bowel movements. This anatomical feature makes it a more likely site for the development of diverticula. As a result, diverticulosis is predominantly found in this area.

Understanding the epidemiology of diverticulosis is essential for both diagnosis and management. Knowledge of the typical locations of diverticular disease helps guide clinical assessments and treatment decisions. While diverticula can technically form in other parts of the colon, the prevalence and clinical significance of diverticulosis are most prominently associated with the sigmoid colon.
