Why does your stomach growl when you are hungry?

Answer 1

Stomach noise - such as rumbling, gurgling and growling - typically is due to normal digestion. Stomach growling can occur when you're hungry. But it can also occur after eating or between meals when food is passing through your intestines.

Hunger and appetite are controlled by a complex system of hormone-like substances primarily made by your digestive system. When you haven't eaten for a while, these substances are released and cause a part of your brain called the hypothalamus to "switch on" your desire to eat. A message is then sent to your stomach and intestines. This triggers muscle contractions and the release of acids and other digestive fluids - which causes the rumbling, grumbling sounds you hear - as your body prepares for you to eat. The thought, sight or smell of food also can trigger this response.

Sometimes excessive stomach noise can be a symptom of an underlying gastrointestinal disorder, such as irritable bowel syndrome. But in such cases, stomach noise usually is accompanied by other signs and symptoms such as bloating, cramping, diarrhea or excess gas.

Answer 2

It happens when your stomach walls squeeze together in an attempt to mix and digest food and there's no food there. Gases and digestive juices slosh around in your empty stomach and before you know it - borborygmi. Yet hunger really has nothing to do with an empty stomach but, instead, is a product of certain nutrients missing in the blood. Our brains contain a "hunger center," which functions as an accelerator, or as a brake, for our stomachs and intestines. Once necessary nutrients are lacking from the blood, the dinner bell is rung, and the stomach and intestines come rumbling. The now active stomach and intestine aren't picky as to what foods will satisfy they, and will grab anything they can. It is the role of the appetite to rein them in, and to ensure that the growling duo are satisfied, but with a healthy balance of the proper nutrients.

Answer 3

Because your stomach constantly churns as it adds digestive juices to food. When empty, the air transmits sound waves more easily than when the stomach is full of food.

Answer 4

This depends. If its making a really long growling noise then your hungry. If its making bubbly or slushing sounds then your having trubble digesting food.

Answer 5

It means that the bubbles inside keep on gurgling.

Answer 6

Perhap you are eating too much sugar. Or hydrochloric acid in your stomach isn't enough to break proteins. Watch what you are eating.
