Achalasia

Esophageal achalasia; Swallowing problems - achalasia; Lower esophageal sphincter; LES; Myotomy

The tube that carries food from the mouth to the stomach is the esophagus. Achalasia makes it harder for the esophagus to move food into the stomach.

Digestive system

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Upper gastrointestinal system

The upper gastrointestinal organs include the mouth, esophagus and stomach.

Normal anatomy

The esophagus carries food from the mouth to the stomach. The lower esophageal sphincter is a muscular ring at the junction of the esophagus and the stomach. The lower esophageal sphincter relaxes when food from the esophagus enters the stomach.
