Overview
Epidemiology and Demographics
Incidence
Pyloric stenosis occurs in 1 of every 200-300 live births
Gender
It is four times more common in males.
Race
It is rare in Asians, and it is 2 to 3 times more common in Caucasian compared to African American babies.
Prevalence
In one study the prevalence of congenital hypertrophic pyloric stenosis in Donetsk region in the course of 11 years (1989-1999) was 0.73:1000 or 1:1370 newborn infants annual with range of 0.54 to 1.01:1000.[1]
Case-fatality rate/Mortality rate
Studies show the mortality rate of pyloric stenosis is very low and usually results from delays in diagnosis that causes sever dehydration and shock.
Age
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Gender
- [Disease name] affects men and women equally.
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
