What happens after swallowing bubble gum?

Usually, some, but not all of the bubble gum will get digested and pass through your body in about a week or so (most foods only take 2 to 3 days). So, if you swallow bubblegum by accident once in a while, you don't need to get worried, but you certainly should not make a habit of it. Because gum digests so slowly, swallowing too may end up blocking intestines, especially in small children.
