Pyloric Stenosis Directory

Pyloric stenosis is a problem with a baby’s stomach that causes forceful vomiting. It happens when the baby's pylorus, which connects the stomach and the small intestine, swells and thickens. This can keep food from moving into the intestine. A baby may get pyloric stenosis any time between birth and 5 months of age. It usually starts about 3 weeks after birth. If your baby was born early (premature), symptoms may start later. Experts don't know what causes pyloric stenosis. It may be passed down through families.
