Aerophagia

Aerophagia (or aerophagy) is a condition of excessive air swallowing, which goes to the stomach instead of the lungs. Aerophagia may also refer to an unusual condition where the primary symptom is excessive flatulence. The actual mechanism by which air enters the gut is obscure or unknown. Aerophagia in psychiatry is sometimes attributed to nervousness or anxiety. Aerophagia affects approximately 0.1–1% of the general population, though prevalence may be underestimated due to underreporting.
