How to reduce gas and bloating

Bloating is a feeling of fullness or visible abdominal swelling. Gas can build up when swallowed air or gut bacteria break down certain carbohydrates. Constipation, fizzy drinks, large meals, and eating quickly can contribute. Bloating is a common presentation of Irritable Bowel Syndrome, while Food Intolerance, Lactose Intolerance, Coeliac Disease, Giardiasis, or Helicobacter Pylori Infection may also present with digestive symptoms. The pattern matters: note meals, bowel movements, pain, and stool changes rather than assuming one cause.

Try smaller meals, chew thoroughly, and reduce fizzy drinks, chewing gum, and foods that repeatedly trigger symptoms. Gentle walking can encourage movement through the bowel. Treat constipation with fluids, activity, and gradual fibre changes; increasing fibre suddenly may worsen gas. Keep a short food and symptom diary, then reintroduce foods carefully instead of removing many food groups at once. A pharmacist can discuss suitable short-term options, and Nutrition Counselling can help create a balanced plan when food triggers are difficult to identify.

Arrange medical assessment for persistent or recurrent bloating, unexplained weight loss, blood in stool, ongoing diarrhoea, repeated vomiting, fever, difficulty swallowing, or a new change in bowel habit. Seek urgent help for severe or rapidly worsening abdominal pain, a hard swollen abdomen, fainting, or inability to pass stool and gas with vomiting. A clinician may examine the abdomen and decide whether testing is needed.

Could constipation, intolerance, or another condition explain the pattern? Which foods should I test first? Do I need examination or tests?
