What should you know about diverticulitis bloating?

Diverticulitis occurs when a small pouch in the bowel wall becomes inflamed. Swelling can change how gas and stool move through the bowel, producing fullness, pressure, cramps or a visibly distended abdomen. Bloating may occur with lower abdominal pain, constipation, diarrhoea, nausea or fever. These symptoms can also have other causes, so bloating alone cannot identify diverticulitis. Read more about [Diverticular Disease](/conditions/diverticular-disease/).

Pay attention to whether the discomfort is new, steadily increasing, associated with a change in bowel habit, or settling between episodes. A symptom diary can help a clinician understand the pattern.

Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if bloating is persistent, keeps returning, or occurs with abdominal pain. Do not start leftover antibiotics or use laxatives without advice. Drink fluids unless a clinician has told you to restrict them, choose foods you tolerate, and avoid foods that clearly worsen discomfort while symptoms are active. Once assessed, [Nutrition Counselling](/treatments/lifestyle-and-wellness/nutrition-counselling/) may help you plan gradual dietary changes rather than unnecessary long-term restriction.

Seek urgent medical help for severe or rapidly worsening abdominal pain, a hard or very swollen abdomen, repeated vomiting, inability to pass stool or gas, faintness, confusion, or a high fever. Blood in the stool also needs prompt assessment. For milder symptoms, contact a clinician soon if they do not improve or are affecting eating, drinking or daily activities. [Abdominal Pain](/symptoms/abdominal-pain/) and [Constipation](/symptoms/constipation/) provide related symptom information.

Ask what other conditions could explain the bloating, whether you need an examination or tests, which foods and medicines are suitable during recovery, and what changes should trigger urgent review.
