Question
The baby experiences vomiting several hours after feeding, with each feeding session involving a small amount of food, most of which is vomited out. This situation started on the second day after birth. Could it be related to hypoxia? The baby is currently being observed in the hospital, and I would like to know how to treat it.
Answer
Vomiting in babies at this age is relatively common and is not likely to be caused by hypoxia. Babies have a horizontal stomach, a small capacity, and a relaxed and inefficiently sealed esophageal sphincter, while the pylorus connecting to the small intestine is tight. Additionally, babies often swallow air during feeding, which makes milk easy to reflux. It is recommended not to let the baby sit up immediately after feeding but rather let it lie on its side for a while before turning onto its back. If the baby is being observed in the hospital, there should be no major concern. Future feeding methods should also be noted.
