Burping; Eructation; Gas - belching
Belching may be due to:
Belching is most often a normal process. The purpose of belching is to release air from the stomach. Every time you swallow, you also swallow air, along with fluid or food.
The buildup of air in the upper stomach causes the stomach to stretch. This triggers the muscle at the lower end of the esophagus (the tube that runs from your mouth to the stomach) to relax. Air is allowed to escape up the esophagus and out the mouth.
Depending on the cause, belching may last longer or be more forceful.
Belching is the act of bringing up air from the stomach.
You can get relief by lying on your side or in a knee-to-chest position until the gas passes.
Avoid chewing gum, eating quickly, and eating gas-producing foods and beverages.
Your provider will examine you and ask about your medical history and symptoms, including:
You may need more tests based on what the provider finds during your exam and your other symptoms.
Most of the time belching is a minor problem. Call a health care provider if the belching does not go away, or if you also have other symptoms.
