Diet and diverticular disease

Diverticular disease describes small pouches in the bowel; some people have no symptoms, while others notice abdominal discomfort, bloating or changes in bowel habit. Constipation and straining can be troublesome for some people. Diet is only one part of care, and there is no universal list of forbidden foods. A sudden change in pain or bowel symptoms needs assessment rather than self-treatment alone.

Add fibre gradually through vegetables, fruit, pulses and whole grains, and drink regularly unless another condition limits fluids. Increase one change at a time so you can notice tolerance. Gentle activity and responding to the urge to open your bowels may support regularity. Keep a brief food-and-symptom record. Nutrition counselling can help if bloating persists, your diet is restricted, or you need alternatives for cultural or medical reasons.

Seek urgent help for severe abdominal pain, persistent vomiting, a swollen abdomen, inability to pass stool or gas, heavy rectal bleeding, faintness or fever with significant illness. Arrange a GP consultation for recurrent pain, ongoing constipation, unexplained weight change, blood in the stool or a bowel pattern that does not settle.

Ask how much fibre and fluid are suitable for you, whether a medicine is contributing to constipation, and which symptoms need review. Discuss whether your symptoms fit diverticular disease, when testing is needed, and whether a dietitian or nutrition counsellor could personalise your plan.
