Esophageal spasm means that contractions of the esophagus are irregular, uncoordinated, and sometimes powerful. This condition may be called diffuse esophageal spasm, or DES.
Esophageal spasm is not common. Often, symptoms that may suggest esophageal spasm are the result of another condition such asgastroesophageal reflux disease (GERD) or achalasia.
