What causes burps and/or belches?!

Sometimes when you swallow these gases, they need to get out. That's where burping comes in! Extra gas is forced out of the stomach, up through the esophagus (say: ih-sah-fuh-gus, the tube for food that connects the back of the throat to the stomach), and out of the mouth as a burp.

Some kids find that drinking soda or other carbonated beverages makes them burp more. Can you guess why? If you're thinking that it's because these drinks contain extra gas, you're right! The gas that makes the drinks fizzy is carbon dioxide (say: kar-bon dy-ahk-side), another gas that can bring on big burps. Sometimes eating or drinking too fast can make a person burp because this can send extra air into the stomach. The same thing happens when you drink through a straw: extra air in = more burps ou

When people eat/drink, they are also swallowing air. This air will then come back out as a burp or belch.
