Lifestyle and home remedies

To help prevent diverticulitis:

• Exercise regularly. Exercise promotes normal bowel function and reduces pressure inside your colon. Try to exercise at least 30 minutes on most days.
• Eat more fiber. High-fiber foods, such as fresh fruits and vegetables and whole grains, soften waste material and help it pass more quickly through your colon. This reduces pressure inside your digestive tract. However, it isn't clear whether a high-fiber diet decreases the risk of diverticulitis. Eating seeds and nuts isn't associated with developing diverticulitis.
• Drink plenty of fluids. Fiber works by absorbing water and increasing the soft, bulky waste in your colon. But if you don't drink enough liquid to replace what's absorbed, fiber can be constipating.
