GERD (gastroesophageal reflux disease or commonly called acid reflux disease) involves the reflux of stomach acids and gastric contents from the stomach into the esophagus, causing esophageal tissue damage. The primary symptom of GERD is heartburn. Laryngopharyngeal reflux (LPR) involves the reflux of stomach acids into the region of the voice box or higher.
Symptoms of LPR vary, but often include chronic cough, thick phlegm, the sensation of something stuck in the throat, chronic sore throat, hoarseness, frequent throat clearing, and/or difficulty swallowing. 50% of patients do not report symptoms of heartburn or upset stomach. Other symptoms of laryngopharyngeal reflux include:
Diagnosis of acid reflux disease is made through a detailed history and physical exam performed by Dr. Kimi Dart and usually includes close examination of the throat using special equipment called flexible laryngoscopy. Treatment is aimed at controlling the production of acid, typically starting with medication and dietary changes.
