What causes the sound (growl) in our stomach when we’re very hungry?
In: Biology
What is producing the sound is a mechanism that happens at all times. It is just more noticeable when the stomach is empty.
When the stomach passes digested food into your intestines, it contracts. This contraction makes a rumbling noise. When your stomach is completely empty, and there is nothing to muffle the noises produced, you hear the growling!
