Question

whydoes your stomach grumble when you are hungry?

Answer 1

Causes of abdominal sounds. The abdominal sounds you hear are most likely related to the movement of food, liquids, digestive juices, and air through your intestines. When your intestines process food, your abdomen may grumble or growl. The walls of the gastrointestinal tract are mostly made up of muscle.

Answer 2

the stomach muscle contractions also help to make us hungry, so we eat foods that our body needs. when these muscle contractions get going again and our stomach is empty , those gas and air pockets make a lot more noise that we hear as stomach growling.
