It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract. In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.
What happens if you swallow a piece of plastic bag?
If it’s a small bag, just a couple of centimeters in size, it’ll probably pass through your intestines like any other non-digestible thing that ends up in your stomach, like fiber or the random coin. That could take one or two days, depending on how fast your body moves waste products.
