What is laryngopharyngeal reflux disease?
Laryngopharyngeal reflux disease is a disorder pertaining to the voice box, vocal cords, and the upper esophagus. Acid backing up from the stomach and into the esophagus can sometimes reach the upper esophagus (pharynx) and affect structures in the area (voice box and vocal cords). Acid can cause irritation to the tissues and result in symptoms in some patients. Typical symptoms include upper respiratory problems such as asthma and chronic cough. Other symptoms may include frequent need to clear the throat, a “lump” sensation in the throat (called “globus” sensation), hoarseness, sour taste, recurrent sore throat or sensations of choking or trouble swallowing.
