Frequent gas and burping: possible reasons

Eating quickly, chewing gum, drinking fizzy drinks, smoking, or talking while eating can increase swallowed air. Certain foods and constipation can increase intestinal gas. Burping with a sour taste, burning, or symptoms after lying down can occur with acid reflux; upper abdominal discomfort or nausea can also occur with gastritis. These patterns do not establish a diagnosis by themselves.

Eat slowly, take smaller mouthfuls, and reduce fizzy drinks and gum for a trial period. Keep a food and symptom diary rather than removing many foods at once. Gentle movement may help trapped gas. Ask a pharmacist before using an over-the-counter remedy, particularly if you take regular medicines. Reflux medicine should be chosen with professional advice when symptoms persist.

Arrange medical review for ongoing symptoms, repeated night waking, difficulty swallowing, persistent vomiting, blood, black stools, unexplained weight loss, or a new change in bowel habits. Seek urgent help for severe or rapidly worsening abdominal pain, a swollen abdomen with inability to pass stool or gas, chest pain, or breathing difficulty.

Ask whether your symptoms fit reflux, gastritis, constipation, or a food-related pattern, and whether medication review or testing is needed.
