How does your body make you throw up?
Normally, your digestive system carries food down your throat, into your stomach, and on through your intestines until what’s left of the food reaches the end of the line at your rectum and comes out as a bowel movement (what you might call poop).
But if you have a virus or other germs in your stomach or intestine, eat food with lots of bacteria (say: bak-teer-ee-uh) in it, feel very nervous, or spin too fast on the merry-go-round, your stomach or intestines might say “this food is stopping here.” When that happens, the muscles in your stomach and intestines push food up instead of down and carry that food right back up to where it started – your mouth.
