What is achalasia?

Esophageal disorder: Achalasia, rare disorder, affects the ability of the esophagus to move food toward the stomach.Muscular ring, sphincter, where esophagus and stomach come together normally relaxes during swallowing. In people with achalasia, sphincter does not relax as well. The reason for this problem is damage to the nerves of the esophagus.Can be idiopathic, caused by infection, or sometimes cancer.

Achalasia: It is a motility disorder of the esophagus when the distal esophagus at the junction with the stomach can not relax, therefore difficult to pass solids and liquids into the stomach.
