Overview

Diverticula are thought to be caused by an increased pressure within the lumen of the colon. Increased intra-colonic pressure secondary to constipation may result in weaknesses in the colon walls giving way to diverticula. Other causes may include high-pressure colonic spasm, which may be due to dehydration or low-fiber diets. Fiber causes stools to retain more water and to become easier to pass during a bowel movement.

Common Causes

• Colonic wall weakness
• Increased intra colonic pressure
• Constipation
• Lack of exercise
• Low-fiber diet
• Older age
• Processed foods
• Frequent straining
