Pediatric Pyloric Stenosis

Key Points About Pyloric Stenosis in Babies

  • Pyloric stenosis is a problem that causes forceful vomiting in babies from birth to 6 months of age. It can lead to dehydration.
  • In pyloric stenosis, the muscles in the stomach that connect to the small intestine thicken. This causes the opening of the pylorus to become narrow. This stops food from moving from the stomach to the intestine.
  • Babies with this condition must have surgery to fix it.
  • After surgery, most babies have no long-term problems from pyloric stenosis.
