I am burping at least 2-3 times an hour for the last 4 days. even on an empty stomach. ?

Burping too much (?): Involuntary belching after a meal is normal, caused by release of swallowed gas after distension of the stomach with food. Magenblase syndrome is postprandial epigastric fullness ; bloating, relieved by belching.Aerophagia (accumulation of gas due to air swallowing) is common with anxiety, hypersalivation from gum chewing, smoking, drinking, oral irritation. In some, belching can become habitual.
