Stomach exit blockag: In a baby with hypertrophic pyloric stenosis (HPS), the circular pyloric muscle fibers which regulate the emptying of the stomach become swollen ("muscle-bound") usually between 2 and 8 weeks' age. The pyloric channel becomes blocked, and fluid cannot exit the stomach. The baby has progressive projectile nonbilious vomiting which can cause dehydration and weight loss if uncorrected.
