Abdominal bloating and burping

Burping releases air from the upper digestive tract, whereas bloating is a feeling of pressure, fullness or swelling in the abdomen. Eating quickly, talking while chewing, fizzy drinks, gum and smoking can increase swallowed air. Large meals and certain carbohydrates may also produce more intestinal gas as they are digested.

The pattern offers useful clues. Symptoms soon after a particular food can fit an intolerance; altered bowel habits and pain relieved after passing stool can occur with irritable bowel syndrome. Coeliac disease, lactose intolerance, Helicobacter pylori infection and some intestinal infections can also present with digestive symptoms, but the combination cannot diagnose any of them by itself.

Slow meals down, chew with the mouth closed, and reduce fizzy drinks, drinking through straws and frequent gum if these increase burping. Smaller meals may feel more comfortable than a large portion. Gentle movement after eating can help gas move through the bowel.

Keep a short diary of meals, symptoms, bowel movements and medicines. Avoid removing several food groups at once, because this can make the trigger harder to identify and leave the diet unbalanced. A clinician or dietitian can guide a focused trial when a food relationship is convincing.

Seek urgent care for severe or rapidly worsening abdominal pain, a rigid or markedly swollen abdomen, vomiting that prevents fluids staying down, blood in vomit or stool, black stool, fainting, breathing difficulty, or inability to pass stool or gas with increasing pain.

Book a medical review when symptoms keep returning, disrupt eating or sleep, or accompany unexplained weight loss, difficulty swallowing, persistent diarrhoea, constipation, fever or ongoing vomiting. Evaluation may include the food pattern, medicines, bowel habits and targeted tests rather than assuming that gas is the only issue.

Ask whether reflux, constipation, an intolerance or another digestive condition fits the timing of your symptoms. Bring your diary and ask which dietary change is worth testing, whether any medicine could contribute, and what new symptom should prompt an earlier return.
