Newborns are prone to vomiting, which may be a non-organic disease or an organic disease, as follows: First, non-organic disease: there is a certain relationship with the child’s digestive system anatomy, as well as digestive function. Because the newborn’s stomach is in a horizontal transverse position after birth, the stomach capacity is small, the pancreatic orifice is flaccid, the pyloric sphincter is tense, the secretion of digestive enzymes is small, and the activity of enzymes is insufficient, and all these reasons will lead to the child’s tendency to vomit. For children prone to vomiting, if the mental state is good, growth and development is not affected, parents can pay more attention to the feeding method, let the child eat more meals, let the child stand for a while after eating milk, burp, which can reduce the child’s vomiting. Second, organic diseases: If the child vomiting is more serious, affecting growth and development, to be alert to organic diseases, such as gastric torsion, congenital pyloric hypertrophy and other diseases, it is recommended that parents take their children to the hospital to do the relevant examination, after the cause of the disease is clearly defined, the causes of the disease to be treated.
