Excessive burping: causes, red flags and when to get it checked

Air gets into the oesophagus through swallowing or sucking. Normally it is released upward as a burp. In some people it happens excessively because of habit, anxiety, certain foods or gut sensitivity. Burping is rarely the sole sign of serious disease.

• Aerophagia: swallowing air when eating or drinking quickly, chewing gum, sucking sweets, smoking, ill-fitting dentures.

• Fizzy drinks and certain foods, including onions, beans and sweeteners.

• Supragastric belching: air drawn into the oesophagus and expelled immediately, often unconscious and linked to anxiety or reflux.

• Gastro-oesophageal reflux and functional dyspepsia.

• Helicobacter pylori infection and gastritis.

• Medicines such as metformin, some antibiotics and anti-inflammatories.

• Hiatus hernia, gastroparesis and gallbladder disease.

• Peptic ulcer or, rarely, stomach cancer.

Unplanned weight loss, difficulty or painful swallowing, persistent vomiting, black stools, anaemia, upper abdominal pain, new symptoms over 55, a persistent lump in the upper abdomen, or loss of appetite warrant assessment.

• Call 999 or go to A&E: burping with chest pressure, sweating or breathlessness.

• Urgent GP: burping with weight loss, difficulty swallowing, vomiting or anaemia.

• GP within weeks: persistent burping with indigestion or reflux not responding to simple measures.

• Routine or pharmacist: occasional burping after fizzy drinks or fast meals.

The doctor asks how often, when, whether burps are sour, related to meals, and any reflux, bloating, nausea, weight change, medicines, alcohol and smoking. They examine the abdomen and may observe how you swallow and burp.

• Helicobacter pylori breath or stool test: to look for infection.

• Blood tests: full blood count and ferritin for anaemia.

• Gastroscopy: if red flags, age over 55 or poor response to treatment.

• High-resolution manometry with impedance: to identify supragastric belching in specialist centres.

• Abdominal ultrasound: if gallbladder disease is suspected.

Eat and drink slowly, avoid gum and fizzy drinks, and sit upright to eat. Avoid drinking through straws and talking while eating. Treat reflux with lifestyle measures. Diaphragmatic breathing exercises, taught by a speech and language therapist, are effective for supragastric belching. Reduce anxiety triggers.

The NHS route is a GP, with speech therapy or gastroenterology if persistent. Private gastroenterology and speech therapy are accessible directly.
