My mind is racing. What does it mean if a girl has pyloric stenosis?

Unusual but... Also occurs in girls. Only one significant difference will be that the offspring from an affected girl has 25 percent chance to develop pyloric stenosis.
Pylorus... ...Is the passage from the stomach to the duodenum. A baby with significant pyloric stenosis will vomit everything she eats because food cannot get from the stomach to the intestine to be digested.
