Neonatal projectile spitting up may be related to improper feeding, gastroenteritis, increased intracranial pressure, digestive tract malformation, etc.
1. Improper feeding: the physiological characteristics of newborns, such as small stomach volume, horizontal stomach position, poor development of cardia sphincter, shorter lower esophageal sphincter, poor gastrointestinal tract power and low secretion of gastric acid and pepsin, make newborns prone to spitting up. For example, too much milk, not burping after feeding, gastroesophageal reflux, resulting in jet spitting.
2. Gastroenteritis: newborns due to bacterial or viral infections, gastrointestinal inflammation, inflammation and metabolic disorders produced by the toxins can stimulate the cerebral cortex and the fourth ventricle under the vomiting center, resulting in projectile vomiting, which can be accompanied by more than just crying, diarrhea and other symptoms.
3. Increased intracranial pressure: Due to the imperfect development of the blood-brain barrier in newborns, pathogenic microorganisms can enter the central nervous system with the blood after infection, causing meningitis and encephalitis, which increase intracranial pressure and can cause projectile vomiting.
4. Gastrointestinal malformations: such as congenital pyloric obstruction, the milk can not pass through the pylorus into the intestines, retention in the stomach, so that the abdominal distension and discomfort, there may be projectile vomiting.
There may be other reasons for projectile vomiting, so it is recommended that you go to the hospital in time for a complete examination to determine the cause of the disease and then give targeted treatment or therapy.
