Pyloric Stenosis Overview

What is pyloric stenosis?
An infant with pyloric stenosis has narrowing of the pylorus, which is the very muscular portion of the bottom of the stomach. Pyloric stenosis blocks the passage of food from the stomach into the intestine. The cause for pyloric stenosis is unknown. Pyloric stenosis occurs in about 1 of every 4,000 newborns.

What are the symptoms of pyloric stenosis?
The most common symptoms of pyloric stenosis include forceful vomiting after eating, and constant hunger. Additional symptoms of pyloric stenosis may include abdominal swelling after eating, frequent belching, and failure to gain weight.

How does the doctor treat pyloric stenosis?
Treatment for pyloric stenosis includes surgery to open the pylorus, so that food may pass from the stomach, into the intestine.
