Chapter 1: Myths About Gum Swallowing

Many of us grew up hearing the exaggerated claim that if we swallow gum, it will remain in our stomachs for seven years or even cause a gum tree to sprout. In this article, we will clarify the reality of what occurs when we accidentally ingest chewing gum.

Digestion Process:

When we chew food, it breaks down due to enzymes found in our saliva, which aids in the disintegration of the material. After we swallow, the stomach's proteins and enzymes continue to break down the food, allowing our intestines to absorb the essential nutrients. Any remaining substance that isn’t absorbed is expelled as waste. However, chewing gum does not break down, regardless of how much we chew it.

Composition of Chewing Gum:

Most chewing gums contain a synthetic rubber-like substance called Polyisobutylene, combined with sweeteners and flavorings that are released during chewing. Thus, swallowing gum is comparable to ingesting a small rubber piece. While the sugars and sweeteners can be processed by the body, the rubbery base remains intact.

What Happens to Swallowed Gum?

Fortunately, the human body has effective methods for dealing with substances that could pose a risk. The digestive system is highly active, with muscular contractions that help move food along, eventually pushing the gum through until it exits through the rectum. Although our body can eliminate this rubbery substance, it’s still wise to avoid swallowing gum, as doing so can lead to a buildup that may cause an intestinal blockage. This is similar to the fate of sweetcorn or corn seeds, which also cannot be digested.
