What should you know about persistent lower abdominal bloating?

Bloating is a feeling of fullness or visible enlargement from gas, altered bowel movement or sensitivity inside the digestive tract. Constipation and irritable bowel syndrome can cause lower abdominal pressure, changes in stool pattern and relief after passing stool or gas. Lactose intolerance or another food intolerance may produce symptoms after particular foods. Coeliac disease, giardiasis and Helicobacter pylori infection are other possibilities considered from the full history, not from bloating alone.

Note when swelling appears, foods and drinks beforehand, stool frequency and appearance, pain, nausea, weight change and whether symptoms wake you. Do not remove many foods for a long period without guidance, because an overly restricted diet can create nutritional problems and make the pattern harder to interpret.

Eat slowly, reduce fizzy drinks, keep portions moderate and maintain gentle activity. Drink enough fluid and increase fibre gradually if constipation is present; a sudden large increase can worsen gas. Keep a food-and-symptom diary rather than repeatedly eliminating foods at random. A nutrition counselling appointment can help test dietary changes safely. Arrange a clinical review if bloating continues, interferes with eating or daily life, or returns despite simple measures.

Seek urgent help for severe or rapidly increasing abdominal pain, persistent vomiting, a rigid or very tender abdomen, inability to pass stool or gas, fainting, or blood in stool. Arrange prompt assessment for unexplained weight loss, ongoing diarrhoea, fever, anaemia symptoms, a new abdominal lump or bloating that is steadily worsening. These features need evaluation rather than dietary experimentation.

Ask whether your bowel pattern suggests constipation or irritable bowel syndrome, whether testing for food-related or infectious causes is appropriate, and how to change fibre or foods safely. Share your diary and ask which warning symptoms should trigger earlier review.
