What should you know about unusual stomach bloating?

Bloating is a feeling of fullness or visible abdominal expansion. Gas, swallowed air, constipation, and eating quickly can all contribute. Reactions to lactose or other foods may bring bloating with cramps, loose stools, or wind. Coeliac disease can cause digestive symptoms after gluten exposure, while irritable bowel syndrome may combine bloating with abdominal discomfort and altered bowel habits. A stomach infection such as giardiasis can also cause bloating and diarrhoea. These possibilities overlap, so the symptom alone cannot identify one cause.

Keep a brief diary of meals, bowel movements, pain, medicines, and when the swelling appears. Eat slowly, chew thoroughly, and try smaller meals; gentle walking may help gas move through the bowel. Drink normally and address constipation with advice from a clinician or pharmacist. Do not remove several food groups without guidance, especially before testing for coeliac disease. A nutrition counsellor can help identify patterns without creating unnecessary restrictions.

Arrange a medical review if bloating keeps returning, does not settle, or comes with weight loss, ongoing diarrhoea or constipation, vomiting, reduced appetite, or blood in the stool. Seek urgent help for severe or rapidly worsening pain, a very swollen and hard abdomen, repeated vomiting, faintness, or inability to pass stool or gas. Tell the clinician about recent travel, new medicines, food triggers, and any family history of digestive disease.

Could constipation, lactose intolerance, or another food reaction explain this pattern? Do I need tests for coeliac disease, infection, or stomach irritation? Which symptoms should prompt urgent review?
