In this lecture Professor Zach Murphy will be presenting on Esophageal Motility Disorders. An esophageal motility disorder (EMD) is a disorder of the esophagus that may cause swallowing difficulties, spasms of pain or regurgitation of food. During this lecture we will be discussing the four main types of esophageal motility disorders. These will include the following:
Achalasia: Achalasia is a rare disorder of the esophagus that affects the ability of the esophagus to move food toward the stomach. It may occur at any age, but is typically more common in middle-aged and older persons. It may be inherited, as well.
Diffuse Esophageal Spasm: This type of esophageal motility disorder is caused by spasm or poor contraction of the smooth muscle that lines the esophagus.
Esophageal scleroderma: As in most autoimmune disorders, the body attacks itself, causing the scarring and thickening of the esophagus tissues. This causes abnormal functioning of the smooth muscle of the esophagus, inhibiting its ability to move food toward the stomach.
We hope you enjoy this lecture!
