Achalasia is a disorder of the esophagus. There is a lower esophageal sphincter, which is a muscle, where the esophagus meets the stomach. In achalasia, that sphincter does not relax enough, there are fewer nerves than normal and there is no peristalsis in the lower two-thirds of the esophagus.
The esophagus is the food tube, or gullet, that carries food and liquid from the mouth to the stomach. The stomach churns the food and secretes a strong acid that aids in digestion. A specialized muscle, known as the lower esophageal sphincter (LES), is located at the end of the esophagus.
