Overview

The incidence of Achalasia is approximately ~ 1 per 100,000. There is no predilection to any age and has the same prevalence in both whites and non-whites.

Age

  • Most commonly, achalasia is diagnosed between 25 and 60 years old, mean age of diagnosis being > 50 years.[4]

Race

  • Achalasia has the same prevalence in both whites and non-whites.[5]
