You're constipated. Constipation can occur when not eating enough fiber-rich whole grains, fruits, and veggies, which stimulate digestion. Adults need between 25 and 30 grams of fiber a day, says Dr. Lee. Best foods: High-fiber whole grain breads, nuts, beans, prunes, oatmeal, flaxseed, broccoli, pears, and apples.
A stomach rumble, also known as a bowel sound or peristaltic sound, is a rumbling, growling or gurgling noise produced by movement of the contents of the gastro-intestinal tract as they are propelled through the small intestine by a series of muscle contractions called peristalsis.
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.
