Symptoms. Many people who have diverticulosis don’t have symptoms, and the diverticula may be discovered only when they go to their doctor for a colonoscopy. If there are no symptoms, diverticulosis does not need to be treated, though some doctors give their patient fiber supplements or probiotics to keep the diverticula from becoming problematic.
If the patient does have symptoms, they may take the form of mild, intermittent cramps. The person may also experience bloating and abdominal tenderness. Cramps and bloating might be eased with a bowel movement or passing gas. A person with diverticulosis may also have bouts of constipation or diarrhea.
