Patient's question:
The baby was born not long ago and has been vomiting non-stop ever since. When they eat, they vomit green water, and they also have loose stools and urinate. These are all normal. At the maternal and child health care center, they performed gastric lavage and observed for a period of time, but no problems were detected. Could you please ask the doctor what causes vomiting in newborns?Doctor's answer:
Newborn vomiting is a symptom during the neonatal period, which may be caused by digestive system disorders or gastrointestinal obstruction. Newborns, especially premature infants, are prone to vomiting due to underdeveloped lower esophageal sphincter, small stomach capacity, delayed emptying time, and low autonomous nervous regulation function of the digestive tract. Causes of vomiting and gastric bleeding include newborn bleeding, stress ulcers, gastroesophageal reflux, temporary dysfunction of pyloric nerves and muscles leading to pyloric spasm, infections caused by gastrointestinal infections, congenital metabolic defects, surgical diseases, improper feeding, and myocardial spasms.
