What should you know about diet during diverticulitis?

Diverticulitis is inflammation affecting small pouches in the bowel. Abdominal pain, tenderness, nausea or a change in bowel movements can make normal meals difficult. A clinician may suggest clear fluids for a short period if eating worsens symptoms, but this approach is not suitable for everyone and should not continue without medical advice.

When discomfort and nausea improve, many people can begin with small portions of soft, low-fibre foods such as soup, yoghurt, eggs, white rice or refined bread, depending on their clinician’s advice. This is a temporary step, not a lifelong restriction. Fibre needs vary, especially if constipation, other bowel conditions or a complicated episode is involved.

Take frequent sips of water or another suitable drink, unless you have been told to limit fluids. Choose modest meals and pause if pain, vomiting or bloating becomes worse. Once you are recovering, add fibre-containing foods slowly, such as oats, vegetables, fruit and whole grains, while continuing to drink enough. A gradual change can be easier to tolerate than suddenly eating large amounts of fibre.

Do not start laxatives, supplements or a restrictive diet to manage the episode without advice. A personalised plan may be useful if you have repeated attacks, ongoing constipation or difficulty meeting your nutritional needs. Nutrition Counselling can help tailor food choices to your symptoms and medical history.

Seek urgent medical help for severe or worsening abdominal pain, a swollen or hard abdomen, repeated vomiting, faintness, confusion, or inability to keep fluids down. A high temperature, blood in the stool, or feeling markedly unwell also needs prompt assessment. Contact a GP if symptoms are not settling, return after improving, or you are unsure whether your eating and drinking plan is safe.

These symptoms can signal dehydration or a complication and should not be judged by diet alone. A GP Consultation can provide an examination and decide whether tests or hospital care are needed.

Ask which foods and drinks are appropriate for your current symptoms, when to progress beyond soft foods, and how to reintroduce fibre. Also ask whether your medicines, kidney or heart condition, constipation, or previous bowel problems change the plan.
