The causes of pediatric diarrhea are infectious diarrhea and non-infectious diarrhea. 1, Infectious diarrhea is mainly an infection in the intestinal tract, which can be caused by viruses, bacteria, fungi, parasites, etc.; 2, Non-infectious diarrhea is often related to dietary factors, allergic factors and climatic factors. 3, the immature development of the digestive tract of infants and young children, less gastric acid in the gastric juice and poor activity of consuming enzymes. And the relative need for more nutrition makes the burden of gastrointestinal heavier, if too much and too early feeding a large amount of sugar or fatty foods, causing consumption dysfunction and easily produce diarrhea. 4.Sudden change in climate and cold can make intestinal peristalsis increase, overheating makes digestive enzymes and gastric acid secretion decrease, thirsty for too much milk can increase the burden on the digestive tract, which also easily causes diarrhea. 5, in addition, infants and young children during the development of the nervous system, endocrine system, circulatory system and liver and kidney function is immature, poor regulation, especially the immune function is weak, when the pathogens with contaminated food into the body, it is very easy to cause diarrhea. Massage can strengthen the neuroregulatory function of the pediatric digestive tract, enhance the body’s resistance, strengthen the spleen and stomach function, and achieve the purpose of preventing and treating diarrhea.
