Why do our stomachs growl?

Your stomach and intestines make sounds often, but you’re more likely to hear them when your digestive tract is empty. This tract is made up of tubes. Muscles in the tubes squeeze to keep foods, liquids, and gases moving along. Your body absorbs what it needs and gets rid of what it doesn’t.

As foods move, they make churning sounds. The sounds are muffled when there’s a lot of food in the tubes. When the tubes are empty, the sounds are amplified. If your stomach has been empty for a while, the muscles squeeze more, which causes even more rumbling. Time to eat!
