Achalasia

What's achalasia? Can I dive if I have it?

A disorder of the esophageal smooth muscle, achalasia has two components: the lower esophageal sphincter that does not relax with swallowing and abnormal contractions that replace the normal movement of the esophagus.

Food and secretions can collect in a pool in the lower esophagus and cause regurgitation when the diver is in the head-down position. As with reflux, diving is not recommended.
