The oropharyngeal swallow with primary and secondary peristaltic contractions of the esophageal body usually transports solid and liquid food boluses from the mouth to the stomach within 10 seconds. Motor abnormalities may not be present with every swallow, so dysphagia may seem to wax and wane. Solid and liquid food dysphagia suggests a neuromuscular disorder, whereas solid food dysphagia only suggests a structural problem causing mechanical obstruction. Very hot or cold liquids, loud noises, and stress may exacerbate dysphagia from esophageal spasm by stimulating muscular contractions.
