Answers. 1  Well it is caused by a few things, the main sound that we as physicains hear is actually the gas moving through the bowels. Some of the sound can also be due to mixing motions of the small intestine. When you are hungry the sound is the the rhythmic clearing of digestive juices by the intestines and stomach. If this gets really loud it and you haven't deficated in a few days it could be borboregmy (spelled it wrong) which is super loud bowel sounds due to an obstruction of feces.
