What is the cause of neonatal vomiting?

The most common cause of neonatal vomiting is improper feeding. Neonatal sucking, swallowing and other non conditional reflex. These reflexes of premature infants are not necessarily perfect, and vomiting often occurs after feeding, especially if the amount of feeding is too much. The mouth and pharynx of newborn are small, and it can cause choking and vomiting when sucking more milk at one time. Neonatal stomach volume is small, a feeding amount is too much, or immediately after feeding supine or excessive rotation, children can also cause vomiting. Nipple hole is too small, children need to suck too hard can also cause vomiting. The milk is too hot and too cold, the newborn contains the nipple to be too deep and stimulates the pharynx and so on can cause vomiting.

Vomiting caused by congenital factors of digestive tract is the main symptom of the disease, but the time and content of vomiting are different with the different parts of the disease: (1) esophageal vomiting. This kind of vomit is milk does not enter the stomach before, in esophagus regurgitates. There is no premonition before vomiting. Vomiting often occurs before the milk is finished. Because the vomit milk does not enter the stomach, the vomit milk does not contain the milk lump, does not mix the stomach acid, does not have the sour odor. Common in esophageal atresia, pylorus relaxation and vomiting caused by cardiac spasm. (2) gastric vomiting. This kind of vomiting is the food has entered the stomach, from the stomach to vomit. Nausea before vomiting. Children restless, stomach content contains gastric juice, so acid odor. Congenital hypertrophic pyloric stenosis and gastric volvulus. (3) small bowel vomiting. It is vomiting caused by intestinal obstruction due to small intestine stenosis or compression. If the lesion is in the upper part of the small intestine, such as 12 fingers intestinal obstruction, children often have abdominal distension, and often vomiting occurs after abdominal distension. Besides milk, there is yellow green bile in vomiting; If obstruction occurs at the lower end of the small intestine, such as the ileocecal valve, abdominal distension is not limited to the upper abdomen, but also in the middle abdomen. The vomiting appeared later and contained bile. (4) colorectal vomiting. Vomiting is caused by obstruction of the large intestine. Hirschsprung's disease and vomiting caused by anorectal atresia belong to this category. Hirschsprung's disease in children with the first performance is constipation, a few days to see a defecation, stool strange odor. As the stool can not be discharged, abdominal distension is more and more serious, abdominal skin is bright and thin, and then vomiting. Besides milk and bile, the contents of vomit can also vomit stool. Anorectal atresia, after birth has been no meconium, followed by abdominal distension, vomiting frequently.

Swallowing amniotic fluid causes vomiting due to the baby swallowing more amniotic fluid, secretion of birth canal, blood, etc. This vomit begins when the baby has not eaten since birth. The vomit is foam mucus, sometimes with brown blood like mucus. Once the contents of the pharynx are spit away, vomiting will stop.
