Belching is a frequent symptom in paediatrics that is negatively perceived in our society and can have a negative impact on the quality of life of patients. However, there is a dearth of data on the subject for the paediatric population. Depending on the origin, belching can be classified as supragastric or gastric, has a different physiology and may be a manifestation of underlying physical or psychological disorders. We review the physiology of belching and the differential diagnosis of 2 cases of supragastric belching.

Clinical case 1: male patient aged 14 years presenting with belching of 15 days’ duration at a rate of 20 to 30 burps per minute, sensation of oesophageal impaction and abdominal pain. The pain improved with omeprazole but the belching persisted, the findings of endoscopy and upper oesophageal transit were normal. The patient improved with speech therapy and initiation of relaxation techniques.

Clinical case 2: male patient aged 10 years-old male presenting with belching of 19 days’ duration at a rate of more than 15 burps per minute, with no other digestive symptoms but with anxiety symptoms. The patient improved with psychological treatment.

The underlying physiology of belching was different in each patient, as in supragastric belching the air does not come from the stomach and the lower oesophageal sphincter remains closed. These 2 types can be differentiated by pH-impedance. Conclusion: A careful anamnesis can establish the suspected diagnosis of the origin of the belching before resorting to diagnostic tests, and can guide the most appropriate treatment for each patient.
