title: [Swallowing disorders: a challenge for the gastroenterologist].
abstract: Alterations in the physiological mechanism of swallowing involve several anatomical structures performing complex and coordinated activities. These alterations can be secondary to various pathological conditions with highly varied causes. Consequently, the approach to patients with swallowing disorders represents a diagnostic challenge. The first difficulty arises in establishing a diagnosis of the syndrome, in which the presence of dysphagia is often the key symptom. The second difficulty lies in identifying the alteration: distinguishing between those affecting the oral and pharyngeal phases and those affecting the pharyngeal phase is clinically important since the etiology and diagnostic strategy will differ. Whenever possible, treatment should be etiological and should aim to restore the swallowing mechanism. Alternative routes for nutrition are sometimes required, either because etiological treatment is lacking or to avoid complications.
