Auscultation and the causes of stomach noises
Stomach noise, which sometimes can be heard on auscultation of the abdomen with a stethoscope or even from a distance, appear in hollow organs that contain gas and liquid, i.e., in the stomach and intestine during movement of their contents. As stated above, the strength of stomach noises caused by movement of fluid through the tube depend on the degree of narrowing and the speed of its current liquid or gas. In addition, the louder the stomach noises are the less is viscous the material moving through the tube mass is.
The lumen of the gastrointestinal tract except for the places of physiological restrictions to be more or less uniform rate due to peristalsis of stomach and bowel movements of a viscous content is low, so the noise created in the stomach and in the intestines, usually weak and at a distance is not heard. Only in the cecum, can be heard with a stethoscope in 4-7 hours after eating a kind of gurgling kind of stomach noises that occur during the transition of the small intestine contents of the blind through the restriction of bauhinia flap.
Enhanced bowel sounds (loud rumbling) may be based on the foregoing, caused by three factors: the emergence of the restrictions in the digestive tract, accelerating the movement of intestinal contents in the intestines increased peristalsis, more liquid consistency of intestinal contents. Because of this, a loud rumbling auscultated along the narrowing of the intestine. At the same time, except for the restriction, on the strength of noise is also affected by the acceleration of the movement of intestinal contents due to increased peristalsis lying above the narrow intestine. In acute inflammation of the mucosa of the small intestine (enteritis) as a loud rumbling auscultated, since there is increased intestinal peristalsis and accelerates the movement of intestinal contents, which also becomes more liquid due to admixture of inflammatory exudates, as well as by lowering the absorptive function of the intestines.
Food or changes in your diet can also be a cause. Some foods that can cause stomach noise include, high fiber foods, milk, carbonated beverages, caffeine, foods with sweeteners, and spicy foods. Try removing them all for a time and then reintroducing them one by one. If you do that, you can find out which foods are causing the stomach noises.
Some loud rumbling neuropathy can also occur without these reasons, due to increased intestinal motility caused by disorders of the autonomic innervation of intestinal muscles. As you can see there are a lot of reasons for stomach noises but in company you never want to hear them.
