How do I know if my child has pyloric stenosis?

  • Many infants appear well with pyloric stenosis. The classic symptom is vomiting. However, with persistent vomiting the infants loose weight and may appear yellow or jaundiced and become dehydrated and lethargic.
  • Your infant's pediatrician and/or surgeon may be able to diagnose pyloric stenosis based on the history and physical exam. The abnormality in the pyloris may be felt by your pediatrician or surgeon.
  • Often, doctors conduct a radiology study, which is helpful in determining if your infant has pyloric stenosis. These radiology studies can include an ultrasound or an upper gastrointestinal series (UGI).
