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.
Normally when food or liquid enters your stomach, a band of muscle at the end of your esophagus closes off the esophagus. This band is called the lower esophageal sphincter (LES). If this band does not close tightly enough, food or stomach acid can back up (reflux) into the esophagus.
