Pyloric Stenosis


Pyloric stenosis is a common problem that occurs in babies during early infancy. Babies with this condition have vomiting as their primary symptom.

  • The vomiting usually happens in infants when they are 2 to 3 weeks old, but can happen as late as 6 weeks old.
  • The vomiting is usually forceful and projectile—it can be so forceful that it can be ejected from one to four feet from your child.
  • The vomit consists of clear fluid or curdled milk.
  • The infants are healthy and vigorous, but develop episodes of spitting up and vomiting that progressively worsen.
  • The vomiting tends to occur within 30 to 60 minutes of feeding. Commonly, after your infant vomits, he is then very eager to eat again.
