High-fiber diet for diverticulosis

Diverticulosis means small pouches have formed in the bowel wall. Fibre holds water and adds bulk, helping stool move through the bowel with less straining. Foods such as oats, wholegrain bread, lentils, beans, vegetables, fruit, and seeds can contribute. Tolerance differs: a sudden increase may cause gas, bloating, or cramping. During active abdominal pain, fever, vomiting, or suspected diverticulitis, a clinician may advise a different short-term eating plan.

Add one fibre-rich food at a time and give your bowel time to adjust. Choose a mixture of soluble and insoluble sources rather than relying on a single product. Drink fluids regularly unless a clinician has restricted them, and keep moving within your comfort. Notice stool consistency, bloating, and pain in a simple diary. Nutrition Counselling can help adapt meals to preferences, other conditions, and medicines. Do not stop prescribed treatment because your diet changes.

Contact a clinician promptly for new or worsening left-sided abdominal pain, fever, chills, vomiting, marked bloating, or inability to pass stool or gas. Seek urgent help for severe pain, faintness, heavy rectal bleeding, or a swollen tender abdomen. Constipation that persists despite gradual dietary changes also deserves review, because the cause may not be diverticulosis.

Ask which fibre sources suit your symptoms, how quickly to increase them, how much fluid is appropriate, and whether abdominal pain or constipation needs further assessment.
