What would cause a child to develop pyloric stenosis after birth?

Unknown: we do not know the true cause of pyloric stenosis. we do know how to recognize and diagnose it. once diagnosed, the surgery is simple and effective. usually only 24-48 hours in the hospital. can be hereditary if one of the parents had it as infant.

No one knows ...: for sure. Given that hypertrophic pyloric stenosis (hps) occurs 5 times more commonly in boys than girls, and 5 times more commonly in whites than blacks (1 out of every 300 newborn white baby boys), there most be some genetic basis to causation. However, there may be some environmental input into causation also.

Pyloric stenosis: Nothing causes it, it's unfortunately one of those things that you are born with. Genes can potentially play a role.
