welcome to disease section for achalasia 

Achalasia, often referred to as esophageal achalasia, is a disorder of the esophagus. The esophagus is a long tube that carries food from your mouth to the stomach. The lower esophageal sphincter (LES) fails to relax in achalasia. This happens because of the degeneration of inhibitory neurons within the esophageal wall.
