What is Pyloric Stenosis?
Pyloric Stenosis is the narrowing of the pylorus (lower part of the stomach which leads to the small intestine) due to the enlargement or thickening of this muscle. This narrowing causes a blockage which makes digestion difficult. The blockage becomes progressively worse until everything ingested is vomited. This disorder is also called Infantile Hypertrophic Pyloric Stenosis (IHPS).
