What should you know about diverticulitis inflamed?

Inflammation commonly causes steady pain or tenderness in the lower abdomen, changes in bowel movements, bloating, nausea or a raised temperature. Symptoms can overlap with other bowel problems, so pain alone cannot confirm the diagnosis. A clinician may ask when symptoms began, examine your abdomen and decide whether tests are needed. Read more about [Diverticular Disease](/conditions/diverticular-disease/) and [Abdominal Pain](/symptoms/abdominal-pain/).

Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if you have new, persistent or worsening abdominal pain. Until you have advice, drink normally if you can, choose foods you tolerate and avoid taking leftover antibiotics. Your clinician may recommend a temporary change in eating, pain relief or treatment for infection depending on the examination. Do not start a restrictive diet without guidance; [Nutrition Counselling](/treatments/lifestyle-and-wellness/nutrition-counselling/) can help if food choices are difficult.

Seek urgent medical help for severe or rapidly worsening pain, a hard or swollen abdomen, repeated vomiting, inability to keep fluids down, faintness, confusion, heavy rectal bleeding or a high temperature with marked illness. These features can signal a complication or another urgent abdominal condition. If symptoms are mild but do not settle, arrange prompt clinical advice rather than waiting for them to disappear.

Ask what findings support diverticulitis, whether you need an examination or scan, which pain medicines are suitable, and when to return to usual foods and activity. Mention previous bowel episodes, medicines, allergies and any [Constipation](/symptoms/constipation/) or bleeding.
