Living with diverticular disease: what to know

Diverticular disease involves small pouches in the wall of the large bowel. Some people have no symptoms, while others notice abdominal pain, bloating or constipation. Diverticulitis is inflammation or infection affecting a pouch and can cause more constant pain, fever or feeling unwell. These terms describe related but different situations, so new or changing symptoms should not be self-diagnosed.

Aim for regular meals, fluids and gradual activity if these suit your health. Increase fibre gradually when advised, because a sudden change can worsen bloating; nutrition counselling can help tailor choices if constipation or food concerns persist. Notice whether pain, bowel frequency or stool consistency changes, and keep a brief record for appointments. Do not take laxatives, antibiotics or pain medicines repeatedly without checking that they are suitable for you.

Get urgent medical help for severe or worsening abdominal pain, a hard or swollen abdomen, repeated vomiting, fever with marked illness, fainting, or significant rectal bleeding. Contact a clinician promptly for persistent pain, a new change in bowel habit, unexplained weight loss, or constipation that is not improving. A GP consultation can help decide whether examination, tests or treatment are needed.

Ask: Is my pain consistent with diverticular disease or something else? How should I change fibre and fluids? Which medicines are safe for pain or constipation? What symptoms mean I should seek urgent help? Would nutrition counselling help me build a suitable eating plan?
