Gas in your stomach and intestines occurs as a natural result of eating and drinking. The food itself can cause gas, or the way you eat can cause you to swallow air and create gas bubbles in your stomach. Over time the gas naturally disperses or passes out of your body through belching or flatulence.
Swallowed Air. Air swallowing (aerophagia) is a common cause of gas in the stomach. Everyone swallows small amounts of air when eating and drinking. However, eating or drinking rapidly, chewing gum, smoking, or wearing loose dentures can cause some people to take in more air. Burping, or belching, is the way most swallowed air--which contains nitrogen, oxygen, and carbon dioxide--leaves the stomach.
