No. Swallowed gum passes through within a few days. Here is what really happens to it, and the rare times it causes trouble.
The myth
Many of us were told as children that swallowed gum stays in the stomach for seven years. It does not.
What really happens
Chewing gum is made of a gum base that the body cannot digest. But the gut does not need to digest something to move it along. Like other things we cannot digest, such as corn skins and seeds, swallowed gum is pushed through the bowel and passed in the stool, usually within a few days.
When it can cause trouble
Very rarely, swallowing a lot of gum often, especially together with other things like coins or seeds, can form a lump that blocks the bowel. This has mostly been reported in young children. An occasional swallowed piece is harmless.
Gum and your gut
- Chewing gum makes you swallow more air, which can cause bloating and burping
- Sugar-free gum often contains sorbitol or xylitol, which can cause wind and loose stools if you chew a lot of it
- On the other hand, chewing gum after a meal increases saliva and can help some people with mild reflux
