Key points about colonic diverticular disease
  • Diverticula are small pouches that bulge out of your gut wall; most occur in your colon.
  • You may be more likely to get diverticula if your diet is low in fiber.
  • Your chances of getting colonic diverticular disease increase as you get older.
  • Colonic diverticular disease may cause painful cramps in the lower part of your abdomen, usually on the left side. You may also experience bloating, a change in your bowels, or blood in your stools.
  • If one or more diverticula become inflamed, you may feel more severe and constant pain, vomit or get a fever.
Once you have diverticula they don’t go away, but many doctors think that you can stop more diverticula from forming and stay well by eating more fiber. If the diverticula become inflamed or infected (called diverticulitis) usually your doctor will prescribe antibiotics for you and monitor how you feel while at home, but if you don’t get better you may need treatment in the hospital.
