Diverticulitis and Diet: Low Fiber as a Cause, High Fiber for Prevention

Diverticulitis involves inflamed pouches (diverticula) in the colon wall. Diverticular disease (presence of diverticula) causes abdominal pain, bloating, constipation. A low-fiber diet is a key risk factor—fiber bulks stool, reduces colonic pressure, and prevents diverticula formation. High-fiber foods: fruits, vegetables, whole grains.
