The causes of burping include nervous habits, gas in beverages, constipation, swallowing and medical conditions, such as gallbladder diseases and ulcer. Burping is a voluntary or involuntary release of air from the esophagus and stomach through the mouth. It can occur three to four times after having a meal due to swallowed air during eating. It can also be referred to as belching.
Burping is a common condition that releases the gas produced in the stomach while breaking down food. The amount of gas a person releases from the mouth can be reduced through changing what he or she eats and drinks. A normal person can experience belching six to 20 times a day depending on what that eat. This condition can be embarrassing, especially when in a crowded place, although it does not result in a serious health problem.
A person who experiences excessive burping can talk to a doctor. A checkup will be needed to find the source of the excessive belching. The doctor will want to know if the person is suffering from any condition that may contribute to the belching. There are no known consequences associated with burping, and it cannot be prevented as it is a natural action.
