Causes of esophageal spasm

The main causes of esophageal spasm include reflux esophagitis, gastroesophageal reflux, esophageal cancer, etc.

1, reflux esophagitis

reflux esophagitis is mainly due to anti-reflux barrier weakened, esophageal clearance capacity decreased, due to inflammatory stimulation can lead to esophageal non-active continuous contraction, resulting in esophageal spasms.

2, gastroesophageal reflux

disease is mainly due to anti-reflux mechanism and functional damage, esophageal clearance capacity decreased, due to gastric contents continued upward reflux, may cause esophageal spasms, spasmodic pain.

3, esophageal cancer

esophageal cancer is mainly due to smoking, nitrite, fungi and other reasons, tumor can damage the surrounding tissues of the esophagus, causing local smooth muscle contraction, resulting in esophageal spasms.
