Megaesophagus is a disorder in which the esophagus dilates and loses motility. When esophageal motility is decreased or absent, food and liquid accumulate in the esophagus and have difficulty getting into the stomach. Regurgitation is the most common sign of megaesophagus. Weight loss or failure to gain weight, as well as aspiration pneumonia, are also common signs. Treatment is focused on managing the symptoms.
