Patient discussion about diverticula

Q. How to prevent diverticulitis? I am a 43 year old man. I just had colonoscopy and my Doctor said I have diverticulosis and am at risk in developing diverticulitis. How can I prevent developing diverticulitis?

A. You have Diverticulosis, which means you have diverticulas (small pouches) on your digestive system. These diverticula are permanent and will not go away. No treatment has been found to prevent complications of diverticular disease. Diet high in fiber increases stool bulk and prevents constipation, and theoretically may help prevent further diverticular formation or worsening of the diverticular condition. Some doctors recommend avoiding nuts, corn, and seeds which can plug diverticular openings and cause diverticulitis. Whether avoidance of such foods is beneficial is unclear. If you develop unexplained fever, chills or abdominal pain, you should notify your doctor immediately since it could be a complication of diverticulitis.
