If you down a lot of food at once or feast too fast, you’ll swallow extra air along the way. Most of this won’t go to your stomach. It will stay in your esophagus, which links your throat to your stomach, until you burp it back up. Slow down when you eat, and chew your food well. Keep your portions smaller, too, so you burp less. Getting to a healthy weight may also make a difference. Extra pounds put more pressure on your stomach.
