3. What are the Causes of Gas Symptoms?

There are several important factors that influence gas related symptoms. These include the amount of air that is swallowed; the efficiency with which the gastrointestinal tract moves and expels the air or gas; and the amount of gas that is produced by the bacteria living in the colon that act on incompletely digested food. There are also individual differences in sensitivity or tolerance to normal amounts of retained gas or the passage of a normal amount of flatus.

4. Can a Person Swallow Too Much Air?

It is clear that some individuals swallow too much air into the stomach. Eating quickly, gulping food or beverages, and other habits such as drinking through a straw, chewing gum, sucking on hard candy or wearing loose fitting dentures may contribute to excessive air swallowing. People also swallow more frequently, and swallow more air, when they are nervous. Air can also be swallowed and released voluntarily as many people are able to belch at will. In some people, excessive belching has become a learned behavior, or habit, that initially may have been associated with some relief of indigestion symptoms, but now continues almost unconsciously.
