Bowel sounds are intermittent gurgling sounds made by the flow of gases and liquids in the intestines during peristalsis, which are clinically known as bowel sounds. Under normal circumstances, bowel sounds are about 4 to 5 times per minute, and the sound is relatively low and gentle, which is difficult to be heard by the general public. However, if the gastrointestinal motility is not normal (too fast, too slow), the bowel sounds are like “gastrointestinal alarms” and may become high-pitched and frequent or slow down and disappear. 1. Bowel sounds alone, more than 5 times per minute, no other symptoms, especially after meals, is likely to be indigestion. Dyspepsia will cause the intestines to produce too much gas, and can not be discharged smoothly, there will be intestinal tinnitus, generally speaking, dyspepsia caused by intestinal tinnitus is not very harmful, eat less indigestible food, take gastrointestinal motivation drugs, and promote gastrointestinal motivation of the probiotic can be. 2. active intestinal tinnitus, that is, the number of intestinal tinnitus more than 10 times per minute, the sound increases but not particularly high-pitched at the same time accompanied by diarrhea, abdominal pain and other symptoms, we should be vigilant against acute gastroenteritis, bacillary dysentery, amoebic dysentery, misuse of laxatives, gastrointestinal bleeding and other gastrointestinal problems. 3. Hyperactive bowel sounds, i.e., the number of bowel sounds is more than 10 times per minute, and the sound is loud, high-pitched, or even tinkling or metallic sound, accompanied by abdominal distension, be alert to mechanical intestinal obstruction. 4. Weakened bowel sounds, bowel sounds significantly less than normal, low sound, 1 minute only to hear a time or even can not hear the bowel sounds. This may be due to constipation, low gastrointestinal motility, peritonitis, electrolyte disorders (hypokalemia) and other conditions. It is recommended to consult a doctor for treatment of abnormal bowel sounds.
