Aerophagia possible: 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.

Elimination diet?: Sometimes a subtle food intolerance can cause gas. Consider an elimination diet where you eliminate dairy, wheat, soy, nuts, citrus, for three weeks and then introduce them one at a time. Keep a journal of the frequency of your gas symptoms.
