Esophageal motility disorder

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).[1]

Primary Motility Disorders are [1]:

An esophageal motility disorder can also be secondary to other diseases[1]. For example, it may be a result of CREST syndrome, referring to the five main features: calcinosis, Raynaud syndrome, esophageal dysmotility, sclerodactyly and telangiectasia.[2]

Symptoms

Symptoms of EMD can include chest pain, and intermittent dysphagia for solids, liquids, or both, and regurgitation.[3] Contractions along the lower esophagus prevent the passage of food.[4]

Types

Dysphagia could be for solids only, or for solids and liquids both.

The most common form of dysphagia is achalasia, which is caused by degeneration of the nerves in the esophagus. This causes the muscles to stop working and prevents the valve at the bottom of the esophagus from being able to open properly.[5]

If there is a food allergy causing the dysmotility disorder, then physicians recommend an elimination diet. If this fails, then physicians will prescribe medication.

Diagnostics

Testing to diagnose EMD includes barium esophagography, upper endoscopy, and esophageal manometry.[6]

Treatments

There is no cure for EMD, but symptoms can be managed. Some symptom management includes eating slower and taking smaller bites; in some cases medications can be useful to manage other issues that contribute to EMD such as a proton pump inhibitor to ease gastroesophageal reflux (acid reflux), or a smooth muscle relaxant for issues with the muscles.[6]
