Dysphagia

 

difficulty in the act of swallowing.

The causes of dysphagia are inflammations of the oral cavity, pharynx, esophagus, larynx, and mediastinum; foreign bodies; cicatricial stenoses and tumors; and certain nervous conditions. Swallowing is difficult or impossible and painful. Food or liquid get into the nose, larynx, and trachea. Dysphagia is treated by eliminating the primary condition.
