Belching

Definition

Belching is the act of bringing up air from the stomach.

Considerations

Belching is 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 of the belching, it may occur more often, last longer, be more forceful.

Symptoms such as nausea, dyspepsia, and heartburn may be relieved by belching.

Causes

Abnormal belching may be due to:

Home Care

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.

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.

What to Expect at Your Office Visit

You may need more tests based on what the provider finds during your exam and your other symptoms.
