Manometry may be done to confirm the diagnosis. It uses a tube to test the pressure in the esophagus and the stomach when swallowing.


There is no cure. The goal of treatment is to allow food and liquids to pass to the stomach. Choices are:

  • Surgery to cut the muscles in the esophagus to allow food to pass
  • Medicines, such as:
    • Muscle relaxants
    • Calcium channel blockers to ease pressure in the esophagus
  • Botulinum toxin injections into the muscles to relax them
  • Pneumatic dilation to stretch the muscles in the esophagus


There are no current guidelines to prevent this health problem.
