Aerophagia is the swallowing of air meaning that air enters the gastrointestinal tract (gut) rather than the lungs. The air may get trapped in the esophagus and/or stomach temporarily and may be passed with an eructation (belch or burp). Aerophagia is not a serious condition but may lead to gas bloating, indigestion and abdominal discomfort. The most noticeable symptom though is excessive belching.

Causes of Aerophagia

Common causes of aerophagia (air swallowing) include :

  • Nasal congestion which leads to mouth breathing.
  • Eating or drinking too fast.
  • Talking too fast or for long periods of time.
  • Strenuous physical activity.
  • Chewing gum.
  • Cigarette smoking.
  • Hysteria or anxiety leading to hyperventilation.
