Celiac disease has been shown to cause problems related to gastrointestinal system motility such as reduction of the esophageal sphincter pressure and prolongation of gastric emptying time. Achalasia disease is a motor disorder that is characaterized by the absence of esophageal peristalsis and by incomplete relaxation of the lower esophageal sphincter. Association of achalasia and celiac diseases has not been reported yet. Our patient with growth and developmental retardation had vomiting effects which lasted for 3 years. Celiac disease was diagnosed serologically and histopathologically in our patient; we determined achalasia disease with esophagoscopic examination, upper gastrointestinal system contrast study, and esophageal manometer. Esophageal balloon dilatation was applied. This case is presented because of the interesting association between celiac disease and achalasia disease.
