Hello and welcome to e health forum.
Burping (also known as belching, ructus, or eructation) involves the release of gas from the digestive tract (mainly esophagus and stomach) through the mouth.
In most parts of the world, especially in formal situations, audible burping is considered impolite.
Gas is typically swallowed when eating or drinking and subsequently expelled during burping.
Almost all normal individuals, are able to burp with no issues. In case if you feel abnormal, you might consult with a doctor for a examination and seek proper counselling and advice.
