Acid Reflux Disease
What is Laryngopharyngeal Reflux (LPR)?
GERD (gastroesophageal 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 voicebox or higher.
Symptoms of LPR
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:
- Mild hoarseness
- Sensation of lump in the throat
- Need to clear the throat from mucous
- Dry tickling sensation in the throat
- Chronic dry cough
- Difficulty swallowing
- Bad taste in the mouth
- Sore throat (especially in the mornings, after meals)
- Red, swollen or irritated voice box
- Chest pain, worsening asthma, emphysema and bronchitis
- Ulcers, granulomas of the vocal cords
Diagnosis
Diagnosis of acid reflux disease is made through a detailed history and physical exam performed by one of our ENT physicians 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.
