Causes and risk factors
Achalasia may occur at any age, but is common in middle-aged or older adults. In achalasia, the lower sphincter fails to relax and open to let food pass into the stomach. The muscles of the lower half of the esophagus does not contract normally, i.e., peristaltic waves do not occur, thus, food is not propelled into the stomach. Factors causing achalasia are esophageal cancers, damage to the nerves of the esophagus, infection with a parasite, Chagas disease, and certain inherited factors.
