Diffuse esophageal spasm; Spasm of the esophagus
Definition of Esophageal spasm
Esophageal spasms are abnormal contractions of the muscles in the esophagus (the tube that carries food from the mouth to the stomach). These spasms do not move food effectively to the stomach.
Causes, incidence, and risk factors
The cause of esophageal spasm is unknown. Very hot or very cold foods may trigger an episode in some people.
Nitroglycerin given under the tongue (sublingual) may be effective in an acute episode of esophageal spasm. Long-acting nitroglycerin and calcium channel blockers are also used to treat esophageal spasms.
An esophageal spasm may come and go (intermittent) or last for a long time (chronic). Medicine can help relieve symptoms.
