Symptoms

Symptoms of EMD can include chest pain, and intermittent Dysphagia for solids, liquids, or both, and regurgitation. There are contractions along the lower esophagus, and these contractions prevent the passage of food.

Diagnostics

Testing to diagnose an EMD include: Barium Esophagography, Upper Endoscopy, and Esophageal Manometry.

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.
