(HealthDay News) — Diverticulosis, a condition that is mainly found in older people, refers to the presence of small sacs that can develop in the lining of the gastrointestinal tract. Although most patients don’t have any symptoms, some experience discomfort in the left lower abdomen, bloating and a change in bowel habits.

The American College of Gastroenterology notes diverticulosis can be diagnosed through a barium enema, colonoscopy or a CT scan. Treatment usually includes antibiotics and, in severe cases, hospitalization.

Those who experience diverticulosis are encouraged to avoid foods that contain indigestible particles, such as nuts and fruits with small seeds.
