“Swallowed chewing gum remains in the human stomach for seven years before being digested or expelled.”

Intervention: Gum chewing for at least 20 minutes every 2 hours starting at the time of capsule ingestion. Main outcome measurements: Small-bowel transit time, gastric transit time, and completion rate were measured. Results: Chewing gum did not have any significant effect on gastric transit time (rate ratio 1.06; 95% CI, 0.73-1.55; P = . 75), small-bowel transit time (rate ratio 0.91; 95% CI, 0.62-1.35; P = . 65), or completion rate (91.67% chewing gum vs 88.71% control, P = . 58) of CE. Chewing gum does not speed up capsule transit or increase completion rate of CE in patients without risk factors for incomplete studies.

Folklore suggests that swallowed gum sits in your stomach for seven years before it can be digested. But this isn't true. It is true that your body can't digest chewing gum. But if you swallow it, the gum doesn't stay in your stomach. It moves relatively intact through your digestive system and passes out of your body in your stool.

The human body cannot digest the gum base. But swallowed gum does not stay in the stomach or cause intestinal problems. That's because our bodies move most materials that can't be digested (like gum) through the digestive system and out of our bodies in a bowel movement (poop).

Luckily for those who have accidentally downed a stick or two, it doesn't take anywhere close to seven years for swallowed gum to exit our bodies, according to Julia Zumpano, a registered dietician at the Cleveland Clinic's Center for Human Nutrition in Ohio. "It takes 40 hours, just as food does, to make its way through your digestive system and out through stool," she told Live Science.

Your parents may have warned you not to swallow your chewing gum because it would remain in your stomach for seven years. Could this possibly be true? ... It is true that the gum base (made from synthetic chicle and similar resilient substances) cannot be digested. The body's digestive system, however, deals with gum base the same way it manages other indigestible substances—by converting it into poop. ... within a few days it is expelled with all the other indigestible parts of your food.

The median GTT was significantly lower in the chewing gum group (29.0 min) than in the control group [42.5 min...]. This indicated that the use of chewing gum during the first hour of the examination could enhance gastrointestinal motility and accelerate the transit of the capsule endoscope through the stomach.

Most people empty their stomachs 30 to 120 minutes after eating, and that includes gum. “The gum base is insoluble, just like the fiber base of raw vegetables, corn, popcorn kernels, and seeds,” says Dr. McGreal. “Our bodies do not possess digestive enzymes to specifically break down gum base.” While it will stick readily to your shoe, gum does not stick to your stomach wall or intestinal tract. Instead of hanging around for years, gum simply travels the same path as food and is excreted in stool.

So don't worry: Gum doesn't stay in your stomach for seven years or even seven days. “If you've swallowed a piece of gum, it'll come out about 40 hours later in your stool,” Czerwony assures. “Because it can't be digested, it comes right out whole.”

You might have heard that swallowed gum stays in your stomach for 7 years. That's not true. Though your stomach can't break down a piece of gum the same way it breaks down other food, your digestive system can move it along through normal intestinal activity. In other words, it comes out the other end when you have a bowel movement (poop).

We've all heard at one time or another that if you swallow gum, it'll sit in your stomach for seven years. This is pure folklore that likely originated from gum being labeled by manufacturers as indigestible. Though entirely untrue, the myth has proven to be a fairly effective way to keep children — and some adults — from swallowing gum.

Chewing gum is used in medical settings as a form of sham feeding to stimulate the vagus nerve, which induces gastrointestinal motility. GTT was shorter (29 minutes) in the gum group than in the control group (42.5 minutes).

While there may be some benefits to gum chewing, there are also some major drawbacks: Chewing too much gum can cause digestive distress and diarrhea due to the sugar alcohols present in most sugar-free gums. The chewing motion signals your body that you're about to digest food; digestive enzymes and acids are activated and released. In the absence of food, this can cause bloat, an over-production of stomach acid, and an impaired digestive process when you actually do eat.

The myth that swallowed gum stays in your system for seven years is false. While gum isn't digested like other foods, it passes through the digestive system relatively quickly and is excreted. Swallowing gum occasionally is unlikely to cause any harm, but habitual swallowing could potentially lead to digestive issues.

The median GTT was significantly lower in the chewing gum group (29.0 min) than in the control group [42.5 min; Kaplan–Meier: hazard ratio, 1.564; 95% confidence interval (CI), 1.137–2.153; P = 0.006; Figure 2]. This indicated that the use of chewing gum during the first hour of the examination could enhance gastrointestinal motility and accelerate the transit of the capsule endoscope through the stomach.

Postoperative gum chewing is an easily implemented, noninvasive strategy supported by quality research that shows that it can shorten the time of return of gastric motility in postoperative colorectal patients. Postoperative gum chewing is a strategy that empowers the patient to participate in their recovery, can shorten the time to the return of gastric motility, and can prevent postoperative ileus.
