Why does my stomach growl?

Stomach growling

Our human body is an amazing machine, and once in a while it will do something to remind us that it’s working hard to keep us alive and well. The stomach growl is one of these reminders. Loud, soft and at times for no good reason at all, your growling stomach has a lot to say.

Whether you call it rumbling, grumbling, gurgling or growling, everybody’s belly chimes in from time to time. These noises may sound like they are coming from a noisy pot of bubbling stew rather than your stomach.

But the big question is, why does it growl in the first place?

The digestive system is, essentially, a long tube that starts at the mouth and ends at the anus. One of the most important things to know about our digestive system is the manner in which it propels food. Waves of muscle contractions move and push the contents continually downward in a process that is called peristalsis. In addition to moving your meal along the digestive path, these contractions also help churn food, liquid and different digestive juices, rendering them into a gooey mix known as chyme.

Stomach growling is the result of this process.
