What should you know about lower abdominal bloating?

Bloating is a feeling of fullness, pressure or visible swelling. Gas can build up when gut bacteria break down food, while constipation can make the lower abdomen feel tight and uncomfortable. Some people notice symptoms after milk, certain carbohydrates or large meals; Food Intolerance and Lactose Intolerance can help explain a repeatable pattern. Irritable Bowel Syndrome may cause bloating alongside abdominal pain and changes in bowel habit. Coeliac Disease, Giardiasis or Helicobacter Pylori Infection are other conditions a clinician may consider when symptoms persist, especially with diarrhoea, nausea or weight loss.

Track meals, bowel movements, pain and the timing of swelling for several days. Eat slowly, chew thoroughly, drink enough fluid, and try gentle walking. Regular toilet habits may help if stools are hard or infrequent. Avoid abruptly removing many foods, because this can reduce nutrition and make triggers difficult to identify; Nutrition Counselling can support a structured approach. Do not start a gluten-free diet before discussing testing for Coeliac Disease, as it may affect assessment.

Arrange medical advice if bloating keeps returning, does not settle, or comes with ongoing bowel changes, vomiting, fever, bleeding, reduced appetite or unexplained weight loss. Seek urgent help for sudden severe pain, a very swollen or hard abdomen, repeated vomiting, faintness, or inability to pass stool or gas.

Ask which causes fit your pattern, whether constipation or food triggers should be assessed, and which tests are appropriate. Bring your symptom and meal record, including medicines and supplements.
