Pyloric Stenosis
Pyloric stenosis is a condition in young infants where the muscle at the outlet of the stomach (pylorus) thickens and blocks food from passing into the small intestine.
When to get help quickly: A baby with persistent projectile vomiting, dehydration signs, or poor weight gain needs prompt hospital review.
Common symptoms
Forceful, projectile vomiting after feeds (often a few weeks after birth), persistent hunger, dehydration, and weight loss or poor weight gain.
When imaging helps
Imaging confirms the thickened pyloric muscle and measures the length and thickness — both used to make the diagnosis.
What radiology does
Abdominal ultrasound is the test of choice; it directly measures pyloric muscle thickness and channel length.
What usually happens next
Treatment is a small operation called pyloromyotomy after correcting any fluid and electrolyte imbalance; recovery is usually quick.
