Does chewing gum stay in your stomach for seven years?

No, this myth is false. Chewing gum does not stay in your stomach for seven years, instead it digests about the same time as everything else. Although, your digestive enzymes can't break down the artificial polymers, resins, and waxes. The myth may have been created since some may have gotten confused by the “can't digest” part, or to discourage kids to not swallow gum. When you swallow gum, your stomach doesn't break down the gum, instead the intestines use rhythmic contractions to push everything to your gut. Swallowing large amounts of gum could block or clog the intestines.
