Which gastrointestinal condition is characterized by diverticula formation due to increased intraluminal pressure?

Diverticulosis is primarily characterized by the formation of diverticula, which are small pouches that protrude from the wall of the colon. This condition arises due to increased intraluminal pressure within the gastrointestinal tract. Factors that contribute to this increased pressure include low dietary fiber intake, which results in harder stools that require more forceful contractions of the colon to move them along. When pressure within the lumen becomes excessive, it can lead to the formation of these pouches at weak points in the colonic wall.

In many cases, diverticulosis itself is asymptomatic; however, if the diverticula become inflamed or infected, the condition can progress to diverticulitis, which presents with abdominal pain, fever, and changes in bowel habits. Understanding the relationship between intraluminal pressure and diverticula formation helps highlight the importance of dietary factors in the development of colorectal conditions.

The other options represent different gastrointestinal disorders with distinct pathophysiological mechanisms and presentations, illustrating that not all gastrointestinal conditions involve diverticula formation or increased intraluminal pressure.
