A normal but embarrassing part of the human condition is to pass bowel gas on a daily basis.
Most people also belch or burp up stomach gas occasionally.
In fact, the average adult on a regular diet passes gas 10 to 20 times a day. This amounts to approximately 1 quart of gas per day. Gas should not be considered excessive unless it occurs at more than twice the normal frequency. The main causes of normal gas are swallowed air, gas-producing foods, and certain diseases that interfere with sugar absorption. This process is increased by sucking on a clogged nipple, a bottle that does not have milk in it, a pacifier, the thumb, or a blanket.
