Achalasia Cardia

Esophageal achalasia is an esophageal movement disorder that affects the smooth muscle layer of the esophagus and the lower esophageal sphincter (LES).

The esophagus is the tube like organ that facilitates food from the mouth to the stomach. The lower esophageal sphincter (LES) is a muscular ring that open after food is swallowed and closes the esophagus from the stomach when empties into stomach. In achalasia, your LES fails to open up during swallowing, which it’s supposed to do. This leads to a backup of food within the esophagus
