When one chews gum on an empty stomach, their body tends to think that they are eating real food so it releases acid. Acid is what breaks down food to digest it. However, since one is not consuming food there is nothing for the body to digest, so the acid begins to break down the layers of the stomach.
What does gum do to your stomach?
But the gum doesn't stay in your stomach. It moves relatively intact through your digestive system and is excreted in your stool. On rare occasions, large amounts of swallowed gum combined with constipation have blocked intestines in children.
Can chewing gum make you gassy?
It's not bunk. When you chew gum, you swallow more often and some of what you're swallowing is air. In addition, artificial sweeteners, such as sorbitol that is found in some gums, can give you gas. Most people produce between a pint and a half-gallon of gas each day.
