High Fibre Diet for Diverticular Disease

Fibre is found in foods such as vegetables, fruit, beans, lentils, oats and wholegrain bread. It adds bulk and can help water move through the bowel. Diverticular disease involves small pouches in the bowel wall; constipation and straining may make bowel symptoms harder to manage, although diet does not remove the pouches.

Increase fibre gradually rather than changing your meals suddenly. Drink fluids regularly unless a clinician has told you to restrict them. Some people notice bloating when they add fibre, and the amount that feels comfortable varies.

Add one fibre-rich food at a time, such as porridge at breakfast, a piece of fruit, vegetables with lunch, or beans in a main meal. Keep a simple record of foods and bowel symptoms so you can identify what suits you. Regular movement can also support bowel regularity.

If constipation continues, a GP or dietitian can help you choose suitable foods or a fibre supplement. Nutrition Counselling may be useful when you need a personalised plan.

Seek urgent medical advice for severe or worsening abdominal pain, a swollen abdomen, repeated vomiting, fever, or blood in the stool. These symptoms can occur with complications that need assessment, and should not be managed by increasing fibre alone.

Arrange a GP Consultation if bowel changes persist, constipation is difficult to relieve, or you are unsure whether your symptoms fit Diverticular Disease.

Ask which fibre target is appropriate for your symptoms, whether a supplement is suitable, how much fluid you should drink, and what warning signs should prompt same-day help.
