Swallowed Gum Stays in Your Stomach for Seven Years

Swallowed gum passes through the digestive system and exits your body within a few days, just like other foods you eat. While gum itself isn't digested, your body treats it like other indigestible items (fibre, seeds). Occasionally, gum can cause blockages if swallowed in very large quantities by young children, but single pieces pose no danger.
