   The doctor in the same hospital who was present knew that he, the pediatrician, loved to commit pediatric occupational diseases, and he didn\'t take his warnings to heart.

   In fact, no doctor dared to neglect Xie Youtian. Even someone like Tan Kelin, who seems to be very cold to children, took a stethoscope and put on earplugs, and deliberately warmed the cold ear of the ear and put it close to the child\'s belly to listen.

   is to listen to the bowel sounds in the child\'s stomach.

   Bowel sounds, sometimes doctors do not need a stethoscope to hear them, but ordinary people can hear them. For example, when people are hungry, they usually say that their hungry stomach growls, which can be said to be a manifestation of hyperactive bowel sounds.

   How did this sound come about. We know that the gastrointestinal tract of the human body is the digestive system. If you want to eat something, you drink liquid from solid food. The gastrointestinal tract itself has digestive juices when you don’t eat anything. At the same time, there is gas in the stomach.

  When the gastrointestinal peristalsis occurs, a physical phenomenon occurs when the gas and the liquid in the gastrointestinal tract are mixed, and the gas passes through the water.

  On weekdays, the human body\'s gastrointestinal peristalsis is in a healthy state, and the sound of gas bubbling in the liquid is relatively mild, such as boiling a frog in warm water, which is low-key and calm. It manifests as normal bowel sounds, grunts less than four or five times a minute, hidden under the belly, and no one can notice without special attention.

When    is unhealthy, the gastrointestinal motility is abnormal, and the bowel sounds will be abnormal. This abnormality can be hyperactive bowel sounds, that is, the gurgles are accelerated; it can also be manifested as a weakening or disappearance of bowel sounds, that is, the gurgles are weakened or disappeared.

  Based on the above reasons, doctors can base on whether there is a peristalsis problem in the patient\'s gastrointestinal tract by listening to bowel sounds, and further infer what may be wrong in the patient\'s gastrointestinal tract.

   Auscultation requires special attention. A doctor wearing a stethoscope is like a musician. By distinguishing the nature of the sound, he can keenly judge the abnormal signals sent out in the human body, which is far more than the simplest number of times.

  Tan Kelin\'s long bangs under his single eyelid eyes had long since frozen at a certain point and could not move, his attention was nothing but his ears.

   The bowel sounds of children, how many times per minute, what is the sound like, is it high pitched? Metal tone? Or is it a more normal bubble sound?

  The people standing around him, no one dared to speak. Qiu Ruiyun and Sun Yubo who were arguing resolutely shut their mouths. If you dare to make a noise again, you will be kicked out of the door with a roar from the boss.

   When a doctor is auscultating, he needs to be quiet, and it is best to be absolutely quiet around him.

  Other experienced doctors don’t waste time listening to Tan Kelin, and they **** up both ears as if they were turned into stethoscopes at the same time. When the bowel sounds are very loud, you don\'t need a stethoscope, and you can hear one or two just by listening.

   Now, in this child\'s little belly: Gugu, Gulu, Gululu... a little louder.

   This sound, definitely more than six times a minute, belongs to the hyperactive bowel sounds. This hyperactivity is basically impossible for the child to growl when he is hungry. The child\'s past medical history is to eat too much. The hyperactive bowel sounds produced by hunger are the result of intestinal tonic contractions. In addition, some mechanical obstructions in the intestinal tract, such as acute gastroenteritis, will also stimulate gastrointestinal motility in disguised form to speed up and produce hyperactive bowel sounds.
