Which statement about diverticula is false?

In the context of diverticular disease, the statement regarding the infection of diverticula is not accurate. While diverticula are indeed pockets that can form in the wall of the colon, indicating a weakening in the intestinal walls, the assertion that most diverticula are infected with gram-negative bacteria does not reflect the typical pathology associated with these structures.

Infections in diverticula, known as diverticulitis, can occur, but it is not the norm for most diverticula to be infected. Instead, diverticula are often asymptomatic and may not be associated with infectious processes unless they become inflamed or infected. The bacteria involved in infection when diverticulitis does occur may include both gram-positive and gram-negative organisms, but gram-negative bacteria are not the predominant species involved in such infections.

Understanding the other statements provides further context: diverticula commonly occur in the colon, especially in individuals with low-fiber diets, as a lack of dietary fiber contributes to increased pressure in the colon leading to the formation of these pouches. Additionally, recommending fiber supplementation, such as psyllium, can help manage and prevent the complications associated with diverticular disease by promoting regular bowel movements and reducing intraluminal pressure in the colon, ultimately lowering the risk of diverticula
