Gas swallowing generally refers to repeated swallowing of air and warmth, often manifested as audible swallowing of air, anorexia, epigastric fullness, excessive anal venting, and recurrent belching, and the symptoms may resolve on their own at night. Air swallowing starts slowly, has a long duration, and is persistent or recurrent. Gastrointestinal symptoms are numerous and may be accompanied by symptoms and features of neurosis. In the examination of gas swallowing, the diagnosis can be based on the following two symptoms. 1. Hysteria globus: Self-perceived discomfort in the larynx, fullness, swallowing, pressure or blockage. It is mostly seen in menopausal women, mostly due to mental factors and compulsive ideas, who often make swallowing movements in order to relieve symptoms. However, there are no symptoms during feeding and no swallowing difficulties. 3, neurological belching (gagging disorder): recurrent episodes of continuous belching in an attempt to belch to relieve abdominal fullness and discomfort caused by self-conscious gastrointestinal inflation, which is actually caused by unconscious and repeated swallowing of large amounts of air (gagging). The disorder has hysterical overtones and tends to flare up in the presence of a bystander, rarely alone with incessant belching.
