Everyone belches or burps at one time or another to relief gas build up in the stomach. It may be often embarrassing but for the vast majority of people occasional belching is not a problem that needs medical attention. The specific symptoms are too much gas in the stomach, drinking gaseous liquids, swallowing too much air, drinking or eating too fast.
Normally, the gas in the stomach is passed down stream into the intestines. Belching occurs when the stomach gas instead of going down, goes up into the oesophagus and is expelled through the mouth.
