Swallowing disorders.
Swallowing is a coordinated activity that enables solids and liquids to pass uninterruptedly from the mouth to the stomach. Dysphagia occurs when this process is disrupted by organic or functional alterations at the level of swallow initiation or esophageal emptying. The differential diagnosis includes obstructive lesions and motility disorders. Symptoms and clinical features help distinguish these diseases.
