In what part of the digestive system do diverticula typically form?

Diverticula typically form in the colon, which is the large intestine. These small, bulging pouches appear when weak spots in the intestinal wall give way under pressure, resulting in outpouchings. This condition is known as diverticulosis, and it is particularly common in older adults due to changes in the structure of the colon as well as factors like a low-fiber diet that can increase pressure in the colon.

The esophagus and stomach do not commonly develop diverticula in the same manner, as they have different structural characteristics and functions compared to the colon. The small intestine is also less likely to develop diverticula than the colon, although diverticula can theoretically form at any point in the gastrointestinal tract. However, it is in the colon where diverticular disease is most prevalent and clinically significant.
