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 a long, thin, and muscular tube that connects the pharynx (throat) to the stomach. It forms an important piece of the gastrointestinal tract and functions as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach.t the inferior end of the esophagus, the lower esophageal sphincter opens for the purpose of permitting food to pass from the esophagus into the stomach. Stomach acid and chyme (partially digested food) is normally prevented from entering the esophagus, thanks to the lower esophageal sphincter.
