Esophageal dysmotility refers to a condition where the muscles of the esophagus do not function properly, leading to difficulties in moving food from the throat to the stomach. This can result in symptoms such as difficulty swallowing, chest pain, and regurgitation. The condition can be caused by various factors, including nerve damage, muscle disorders, or certain diseases. Diagnosis typically involves tests like esophageal manometry, which measures the pressure and coordination of esophageal contractions. Treatment options may include dietary changes, medications, or in some cases, surgical interventions to improve esophageal function and alleviate symptoms.
