The most common symptoms noted in a baby with pyloric stenosis is forceful, projectile vomiting. This kind of vomiting is different from a "wet burp" that a baby may have at the end of a feeding. Large amounts of breast milk or formula are vomited, and may go several feet across a room.

Babies with pyloric stenosis usually have progressively worsening vomiting during their first weeks or months of life. The vomiting is often described as non bilious and projectile vomiting, because it is more forceful than the usual spit ups commonly seen at this age.

Pyloric stenosis is a condition that affects an infant's pylorus, a muscle at the end of the stomach. When the pylorus thickens, food can't pass through. Pyloric stenosis symptoms include forceful vomiting, which may cause dehydration. Surgery can repair the problem.

The hallmark of pyloric stenosis is marked hypertrophy and hyperplasia of both the circular and longitudinal muscular layers of the pylorus. [3] This thickening leads to the narrowing of the lumen of the gastric antrum. The pyloric canal becomes lengthened. The muscles of the pylorus become thickened.
