Other than indicating hunger, why exactly do our stomachs growl?

1.it may be because of gastric problem\n2.it is because your stomach secretes hydrochloric acid and other digestive enzymes when u feel hungry

A person is supposed to eat every 4 hours(it takes so long for complete digestion of the food).\n\nWhen we have not eaten food for some time,the stomach is empty.the stomach wall will secrete acids(HCl) and enzymes for digestion of food wether food is present in stomach or not...this results in accumulation of acid and enzymes in the stomach which causes the "grumbling noise" in the stomach.\n\nThis signal's to the brain that the body needs food...thereby causing hunger pangs.

Chewing gum is not an alternative to eating. chewing gum triggers the body to produce digestive enzymes which with no food in the stomach can cause ulcers.Secondly alot of people confuse thirst with hunger pangs, so try drinking an eight oz. glass of water if it has only been 1-2 hours since your last full meal.

A couple of things, actually.  Digestion starts from the moment you start to chew up your food as certain enzymes begin to break down the proteins.  The gastrointestinal (GI) tract is protected from them to a large degree by mucus which lines the intestines and stomach.  The mucus also protects the stomach from the acid which is kept in the stomach.  \n\nSo that stuff which drives you nuts when you have a runny nose does really have something useful to do!

belch?\n\nburping also known as belching, ructus or eructation, is the release of gas from the digestive tract (mainly esophagus and stomach) through the mouth. It is often accompanied with a typical sound and sometimes an odor.

Most possibly is that it was the reaction when the digested food got in to the stomach.\n\nthe reaction is just like when you plunge something solid into a pool of liquid, there will be some gas escaping...\n\nOur stomach was just like a pool containing digestive liquids and enzyme, thus, the digested food "plunges" itself into the stomach, thus the gas escapes, this, and the movement of the muscle made the rumbling sound in our stomach

Your stomach makes noises because your it is contracting and trying to digest but all that is in there is your gastric juices, it's kind of like squsihing a water ballon that is only a little bit full

There are several factors in your gastrointestinal system that make it do those noises.\nFirst, it is in constant movement due that it has its own nervous system which keeps it in movement so that all the nutrients can go through the system and can be absorbed at different points of your intestines; and there are a lot of hormones that help with this movement too, but they are activated in a more cyclic pattern according to when you had your last meal.\nInside the gastrointestinal system there are a lot of things that make funny noises when they are moved, all the food is in liquid form because the stomach used its acid and its movements to disolve and crush everything you ate, and in your small and large intestines there are billions of bacteria that produce gas; when you move liquids they make noise and if you mix gas and liquids you get bubbles that when pop make noise too.\nSo in conclusion the noise comes from the constant moving of the contents of your gastrointestinal system led by the nervous and endocrine system.

Eating is usually a way of suppressing something that is bothering you.  Find out what you are stressing about, work on that and your hunger will subside.  Sounds weird but is true.

Yes this is true. I learned this through dieting advisers. The reason being that our stomach is so busy trying to process the food, that when we try to focus our energy on some other activity, our body revolts by cramping up.

it can be gas pains or from the body cramping up. when you are digesting you need blood to do so, if you are runing yuou are using the blood for activity, the bodies natural response is to cramp up to tell the body it needs more blood in that area.

1. activity varies day to day, increased activity needs more energy and your brain tell you to eat more\n2. on contrary, when you have nothing to do, it's easy to get your attention of food, especially if there is easy and tasty one nearby\n3. you don't eat the same thing everyday don't you? what you eat before affect your hunger. food that hard to digest stay longer in your stomach and make you feel full for longer time. it's not just calories or grams that counts

This came up in my sister's wildlife biology class--in the wild, animals that live in herds do something similar to a yawn when everything is peaceful and there is no danger lurking (like lions), and the yawn passes from one animal to the next as a signal.  Apparently the biological urge is in humans as well--maybe we are passing along that we are relaxed and not feeling threatened.

You feel it and hear it because the walls of the stomach are rubbing past each other, rather than the food that should be there.  It is a way your body tells you to eat something!  However, after a few more hours without food, the churning ceases, as the body starts to use stored fat for fuel, not ingested food.  The body begins its "starvation mode" and conserves energy, lowers metabolism, and burns stored fat

Because a lot of your blood is being moved to your stomach and intestines to digest your food.  Perhaps you have low blood volume or poor circulation.  You might want to see a doctor.

It's an innate quality they have.\n\nWhen human babies are breastfeeding they automatically know how to do it. (Whether or not they warm up to Mom is a different story). Or when human babies cry because they are hungry, or tired, or bored...same thing.\n\nOr in human adults...when something scares us automatically our hearts race, our pupils dilate, our digestion slows...all to get us ready to run.\n\nIt's just a natural, in-born trait. Kinda like a reflex.
