Overview

The incidence of infantile pyloric stenosis is approximately 400 per 100,000 individuals worldwide and it is four times more common in males. It usually affects individuals of the Caucasian race. Asians individuals are less likely to develop infantile pyloric stenosis. The prevalence of infantile pyloric stenosis in the course of 11 years (1989-1999) was approximately 7.3 per 100,000 individuals in one study. It is observed that the mortality rate of pyloric stenosis is very low and usually results from delays in diagnosis that causes severe dehydration and shock.

Mortality rate

Gender

  • Males are more commonly affected by infantile pyloric stenosis than females.[4]
  • The male to female ratio is approximately 4 to 1.

Race

  • Infantile pyloric stenosis usually affects individuals of the Caucasian race.[1]
  • Asians individuals are less likely to develop Infantile pyloric stenosis.
