Is Swallowing Gum Dangerous?
Most of us have been warned at some point: “Don’t swallow your gum—it’ll stay in your stomach for seven years!” It’s a phrase passed around in classrooms, at dinner tables, and even on playgrounds.
But is it true? Does swallowed gum really sit in your stomach for years, or is that just another childhood myth? Let’s find out what actually happens when gum goes down the wrong way.

What Happens When You Swallow Gum?
When you eat regular food, your body breaks it down with stomach acids and enzymes. Proteins, carbs, and fats are absorbed, and what’s left is eliminated.
Chewing gum is different.
The gum base—the chewy, rubbery part—cannot be digested.
The flavorings and sweeteners are digestible, so your body absorbs those like normal.
In simple terms: the gum base stays intact but doesn’t stick around. It passes through your digestive system and comes out a few days later, just like corn kernels or other foods your body can’t fully break down.
The 7-Year Myth
The idea that gum sits in your stomach for seven years is pure myth. Doctors agree that gum doesn’t cling to your stomach walls or linger in your digestive system for years.
Instead, your intestines push it along like any other indigestible material, and it leaves your body naturally.
So, if you’ve ever swallowed gum by accident, rest assured—it won’t haunt your stomach for the next seven years.
Risks of Swallowing Gum
For most people, swallowing gum occasionally is harmless. But are there risks? Yes, though they’re rare.
Blockages (Bezoars): Swallowing large amounts of gum, especially along with other indigestible things (like seeds or coins), can form a mass called a bezoar. This may block the digestive tract.
Children at Higher Risk: Kids have smaller digestive systems, and they’re more likely to swallow gum along with other objects. This makes them slightly more vulnerable to complications.
Constipation: Frequent gum swallowing in children has been linked to constipation and stool-blocking cases, according to the American Academy of Pediatrics.
Choking Hazard: Beyond digestion, gum can be a choking risk if swallowed the wrong way—particularly for younger children.
Bottom line: The risks exist, but they’re uncommon. Swallowing one piece by accident isn’t dangerous. Problems usually come only from swallowing gum often or in large amounts.
Why the Myth Spread
So if gum doesn’t actually stick to your stomach, why did so many of us grow up believing it? The likely reason is that adults used the “seven years” scare tactic to stop kids from swallowing it.
It’s the same category of myth as:
“If you cross your eyes, they’ll get stuck that way.”
“If you swallow watermelon seeds, a plant will grow inside you.”
Not true, but memorable enough to make kids think twice.
What’s Really Inside Chewing Gum?
To understand why gum isn’t digested, it helps to know what it’s made of:
Gum base: The indigestible part that gives gum its chewiness.
Sweeteners: Sugar, xylitol, or other substitutes.
Flavorings: Mint, fruit, or spice extracts.
Softeners: Ingredients like glycerin to keep it flexible.
Everything except the gum base is digestible. That’s why gum passes through your body intact.
What Doctors Say
Health experts are clear:
Swallowing gum once in a while is not dangerous.
Gum does not stay in your stomach for years.
Complications are rare and usually linked to frequent swallowing or swallowing gum with other indigestible items.
The American Academy of Pediatrics has reported rare cases where children developed blockages after swallowing multiple pieces of gum. But these cases are the exception—not the rule.
Final Answer: Is Swallowing Gum Dangerous?
For most people, no. Accidentally swallowing gum won’t harm you, and it definitely won’t sit in your stomach for seven years. Your body simply moves it along until it exits naturally.
That said, gum is made for chewing, not eating. The safest habit is to spit it into the trash when you’re done. For kids especially, it’s good to set this rule early to avoid any rare but possible problems.
