If I swallow gum, does it stay in my stomach for 7 years?
The Real Answer
No. Your body can't fully digest the gum base, but that does not mean the gum stays in your stomach. It moves through the digestive tract relatively intact and eventually leaves your body in stool. The seven-year story is a myth.
Accidentally swallowing an occasional piece is generally harmless. Very rarely, however, large amounts of swallowed gum—especially in children and sometimes combined with constipation—have contributed to intestinal blockages. So your stomach doesn't keep a seven-year gum archive, but swallowing large quantities still isn't a good idea.
Your body is a factory that turns pizza into poop, and gum is the one thing it refuses to process. Your stomach looks at it, shrugs, says “not my problem,” and hands it to the next department. Somehow parents turned that free ride through the factory into a seven-year prison sentence—by the time that second-grade gum got out, it was supposed to be in high school.

The seven-year warning is memorable because it gives a simple consequence to something children are told not to do. The number sticks long after the reason for believing it disappears.
