It can be embarrassing when stomachs make noises, but they have their reasons; a lot is going on in there.
When your stomach is empty, and there’s nothing for the stomach acid to do, it doesn’t just go away.
It churns and produces gases as it bubbles and waits, impatient for you to feed it.
When food does come down the pipe and drop into the brine, the digestive juices make noises as they work on the food as well.
So here’s the bottom line, don’t worry too much about it. Although your stomach sometimes talks to you when it needs something, you don’t really have to talk back. Just listen and nod your head in affirmation.
