How to treat babies with forceful vomiting (pyloric stenosis)

Pyloric Stenosis (or infantile hypertrophic pyloric stenosis) is a condition characterized by forceful vomiting in an infant due to hypertrophy of the pylorus muscle leading to gastric outlet obstruction. This means the muscle where the stomach empties into the small intestine becomes too thick and prevents emptying. As a result, after eating, the baby vomits. The reason for this happening is not known but is likely caused by many things and family history can play a role. Pyloric stenosis is rare, occurring in about 3 of  every 1,000 live births, and most often occurs between the ages of 3-6 weeks, is more common in males, and 1/3 of the time occurs in a first-born child.
Vomit from pyloric stenosis usually consists of just milk or formula. Any vomit with color should raise suspicion for other diagnoses. Parents report vomiting from pyloric stenosis as forceful and projectile. Infants are often hungry after vomiting, wanting to continue eating, however eating usually continues the cycle of vomiting.
