The Mystery of the Growling Tummy Monster: Why Your Belly Makes Funny Noises

Have you ever heard your tummy make funny noises? Sometimes it sounds like a little monster is hiding inside you! GRRRROWL! RUMBLE! GURGLE! But don’t worry—there’s no monster in there. Your amazing body is just doing its job!

What Makes Your Tummy Growl?

Your tummy (scientists call it your “stomach”) is actually a strong muscle. Just like how you can flex your arm muscles, your tummy muscles can squeeze and stretch too!

When your tummy muscles move around, they push air and liquids through your insides. This creates those funny rumbling sounds—just like how squeezing a water balloon makes squishy noises!

The really cool thing? Your tummy makes these sounds even when you’re NOT hungry! But we often notice them more when we haven’t eaten in a while.

The Hungry Tummy Symphony

When you haven’t eaten for a few hours, your body sends special messages that say, “Hey! It’s time to find some food!” This makes your tummy muscles squeeze even harder, creating louder growls and rumbles.

These sounds have a special name: borborygmi (bor-boh-RIG-mee). Isn’t that a silly word? Try saying it three times fast!

Your Tummy Does Important Work!

Your tummy muscles are very important. They:

Mix up your food with special juices that help break it down
Push food through your body so it can give you energy
Clean things out between meals when your tummy is empty

Is there a difference in the sounds?

Extra Challenge: Make a “Tummy Sound Journal” where you draw pictures of what you think the sounds look like. Are they loud like a lion or quiet like a mouse?
