When the walls are activated and squeeze the tract's contents to mix and propel food, gas and fluids through the stomach and small intestines, it generates a rumbling noise. This squeezing of the muscular walls is termed peristalsis and involves a ring of contraction moving aborally away from the oral cavity towards the anus a few inches at a time.
The generation of these waves of peristalsis results from a rhythmic fluctuation of electrical potential in the smooth muscle cells, which, all other conditions being appropriate, will cause the muscle to contract. This fluctuation is called the basic electrical rhythm BER and is a result of inherent activity of the enteric nervous system, which is found in the walls of the gut.
The BER causes the muscle cells of the stomach and small intestines to activate at a regular rhythm three and 12 times per minute, respectively , in a manner similar to, but slower than, the rhythmicity of cardiac muscle in the heart.
The autonomic nervous system and hormonal factors can modulate this BER. Though the rate and force of peristalsis typically increases in the presence of food, activity also increases after the stomach and small intestines have been empty for approximately two hours.
In the latter case, receptors in the walls of the stomach sense the absence of food, causing a reflex generation of waves of electrical activity migrating myoelectric complexes, or MMCs in the enteric nervous system. These MMCs travel along the stomach and small intestines and lead to hunger contractions. Such hunger contractions start in the antrum, or lower region, of the stomach and propagate along the entire length of the gut, sweeping to the terminal ileum.

Fortunately, there are several ways to stop your stomach from growling. It can be confusing when your stomach rumbles and you really aren't hungry, so why does it happen and can it be prevented?
Also known as borborygmi, bowel noises are produced when vigorous movements of the gut shuffle liquid and gas contents of the intestine backwards and forwards. However, it's important to note that all noise doesn't come from the stomach alone, even if it seems that way. Sounds come from the whole digestive system, including the small intestine or colon.
Julie Thompson, Information Manager at Guts UK , says while a noisy gut can be caused by hunger, it may be from anxiety or fright. She also says stomach noises are very common in IBS , but particularly loud rumblings from the intestines can be caused by gut problems such as Crohn's disease or bowel obstruction. These conditions are associated with other symptoms, such as severe abdominal pain, and should be reported to your doctor. Borborygmi can occur at any time and are the sounds of peristalsis - a series of wave-like muscle contractions that mix food in the stomach with liquids and digestive juices and move food along through your intestines.
During this process, air and gases produced by digestion, also get squeezed and make noises. A rumbling or growling stomach is a normal part of digestion and the body's way of communicating hunger. Because there is nothing in the stomach to muffle or silence these rumbles, they are often noticeable. Rumbling of an empty stomach will last minutes out of every hour, until you fill your stomach up again. It is common both before eating - when you likely feel most hungry - and hours after your last meal.
