Burping Guide, Meaning , Facts, Information and Description
The process of burping, also known as a belching, is an often audible release through the mouth of gas that has accumulated in the stomach or esophagus.Burping is typically caused by eating or drinking too fast, and thereby swallowing (aerophagia) and subsequently expelling air, in which case the expelled gas is a mixture of nitrogen and oxygen. Burps can also be caused by imbibing carbonated drinks such as beer, soft drinks, or champagne, in which case the expelled gas is carbon dioxide produced by the drink itself.
In the Western world burping is considered impolite (although not as socially unacceptable as farting), and so some people will cover the mouth with their hand in the same fashion as one used to guise a yawn.
Babies are particularly subject to accumulation of gas in the stomach whilst feeding, and this can cause considerable agitation to the child unless it is burped. The act of burping an infant involves placing the child in a position conducive to gas expulsion (for example over the adult's shoulder, with the infant's stomach resting on the adult's chest) and then lightly patting or rubbing it on the back so that it burps. Because burping can cause vomiting in infants, a euphemistically-named burp cloth or burp pad is sometimes employed on the shoulder to protect the adult's clothing.
It is possible to voluntarily induce burping by swallowing air and then expelling it, and by manipulation of the vocal tract produce 'burped' speech. While this is often employed by children as a means of entertainment, it can also act as an alternative means of vocalisation for people who have undergone a laryngectomy, with the burp replacing laryngeal phonation. This is known as esophageal speech.
Other mammals, such as horses, cows, and sheep also burp; in these cases, the gas expelled is actually methane produced as a byproduct of the animal's digestive process.
