| diverticulitis, bleeding from | Diverticular bleeding typically occurs intermittently over several days. Colonoscopy is usually performed to confirm the diagnosis and exclude bleeding from other causes. Thermal probes cannot be employed to stop active diverticular bleeding. Therefore, surgical removal of the bleeding diverticula is necessary for those with persistent bleeding. (12 Dec 1998) |

| diverticulitis, treatment of acute | Antibiotics are usually needed. Oral antibiotics are sufficient when symptoms are mild.

Surgery is needed for persistent bowel obstruction or abscesses not responding to antibiotics. (12 Dec 1998) |
| diverticulosis/diverticulitis and fibre | High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. (12 Dec 1998) |
