In this condition, gastric outlet obstruction results from hypertrophy of the pyloric muscle, edema of the pyloric canal, and spasm of the antropyloric muscle, which leads to vomiting, dehydration, and metabolic alkalosis.

Clinical manifestations of pyloric stenosis begin at a mean age of 3 weeks after birth, but they may occur at any time between birth and 5 months of age.
