Just thinking about food sends signals to your digestive organs to prepare them for a meal. These signals not only step up the intensity and frequency of contractions by the stomach and intestines - they also stimulate them to secrete digestive juices.
Even if there's no food your stomach is still working if you're thinking about eating!
Eat.
It's not your stomach that makes the noise. It's air and waste in your intestines.
It growls because when food is in your stomach your stomach churns up your food, and when it is empty it growls. Welcome to the wonderful world of DIGESTION. If you've enjoyed some of the foods and/or beverages that contribute to a gassy buildup - beans and carbonated beverages - you can expect that there will be some methane created later in the day.
no, this is a common misunderstanding. When your stomach growls it is battling mini unicorns.
Your stomach growls when it is empty, the noise is caused from air pushing through your digestive system.
