What Causes Diverticulitis?

9. Low-Fiber Diets

Diverticulitis is becoming more common in the U.S., and most experts say that a diet that is high in fiber plays a crucial role. This may be due to the way fiber bulks up an individual’s stool, requiring less pressure from the colon. A person who adopts a low fiber diet has a drier stool that is harder to push out. Stool that sticks in the colon can become infected and lead to diverticulitis. There is no evidence that a high-fiber diet will prevent diverticular pouches. However, medical researchers say a fiber-rich diet may prevent diverticulitis.
