Pyloric Stenosis

What is pyloric stenosis?

Pyloric stenosis (pronounced pie-LOR-ik sten-OH-sis) is a thickening in the muscle at the end of the stomach called the pylorus. The enlarged muscle can block or slow the passage of food from the stomach to the intestine. This can cause symptoms such as vomiting, often in a forceful way (projectile vomiting).

Pyloric Stenosis in Children

Pyloric stenosis is a common problem for babies between 2 weeks and 3 months old. It affects about 1 in every 300 babies.
