An esophageal motility disorder (EMD) is any medical disorder resulting from dysfunction of the coordinated movement of esophagus, which causes dysphagia (i.e. difficulty in swallowing, regurgitation of food).
Primary motility disorders are:
- Achalasia
- Diffuse esophageal spasm
- Nutcracker esophagus
- Hypertensive lower esophageal sphincter
An esophageal motility disorder can also be secondary to other diseases. For example, it may be a result of CREST syndrome, referring to the five main features: calcinosis, Raynaud syndrome, esophageal dysmotility, sclerodactyly and telangiectasia.
