Why does my belly growl when I get hungry?

Although it might sound like growling coming from a throat, that rumbling and grumbling you hear comes from the stomach and the small intestine. And it happens at all sorts of times — not just when you’re hungry!

As the muscles of your digestive system push food through the digestion process, the food gets broken down to be used by your body. In addition to the food and liquids that move through your digestive system, gas and air bubbles also get into the mixture.

It is these pockets of gas and air that make the sounds you know as stomach growling. They’re not as loud when you have food in your stomach, because the food absorbs some of the sound.

When your stomach is empty, though, these sounds are much more noticeable. That’s probably why we associate stomach growling with being hungry. A couple hours after you eat, your stomach sends signals to your brain to get your digestive system muscles working again.

This process cleans up any food that was missed earlier. The stomach muscle contractions also help to make you hungry, so you eat more food that your body needs. When these muscle contractions get going again and your stomach is empty, those gas and air pockets make a lot more noise that you hear as stomach growling.
