Hypertrophic Pyloric Stenosis
Symptoms of Hypertrophic Pyloric Stenosis
Symptoms of hypertrophic pyloric stenosis typically develop when an infant is 3 to 6 weeks old. Infants with pyloric stenosis are hungry and feed well but vomit forcefully (projectile vomiting) shortly after eating. Some infants vomit so much that they become dehydrated and undernourished. Until dehydration is severe, or infants become significantly undernourished, they otherwise appear well. After several days to weeks, infants become progressively dehydrated and lose weight. Some infants have a yellowish discoloration of the skin and the whites of the eyes (jaundice) at this point.
