The baby often vomits after eating milk. Why is this?

In some babies, frequent spray vomiting may be caused by hypertrophic pylorus (HPS), and one of the 500 babies will occur HPS.

What is HPS?

HPS is the narrow of the pyloric door, that is, the muscle valve at the bottom of the stomach. When it becomes hypertrophic, breast milk or formula milk cannot enter the small intestine, which causes excessive jet vomiting, usually 2-6 weeks after birth.
