You didn't say if it was nicotine gum?
I found this on swallowing regular chewing gum: "Although chewing gum is designed to be chewed and not swallowed, it generally isn't harmful if swallowed. ... If you swallow gum, it's true that your body can't digest it. But the gum doesn't stay in your stomach. It moves relatively intact through your digestive system and is excreted in your stool."
I found this on nicotine gum: "If you swallow the gum or use it improperly, you could have hiccups, dizziness, nausea, or upset stomach." If you are using nicotine gum, you should be parking it in between your cheek and gum - not chewing it like regular gum.
I would figure out why you are swallowing it and do something differently so you stop it. Although regular gum doesn't appear to be harmful, it can't be good long term for your digestive system.
Try maybe Dum-Dum lollipops, or Sour Path Kids or Fireball candies, maybe, or sugar free mints?
You aren't smoking, though, and that is a GOOD thing!
Doesn't seem like one piece should be a problem. What I found is that it passes completely through your system undigested (and comes out the other end!).
