When left untreated, laryngopharyngeal or gastroesophageal reflux can cause damage to your throat, esophagus, or voice box. Read on to learn more about the common symptoms, diagnosis, and treatment of LPR.
There are two sphincter muscles in your esophagus that close the esophagus at its upper and lower portions.
If both the upper and lower esophageal sphincters don’t function properly, the acid backflows into the esophagus, penetrating the throat and voice box; this is called Laryngopharyngeal Reflux or LPR.
When only the lower esophageal sphincter is not functioning properly, there is a backflow of stomach acid into the esophagus, called Gastroesophageal Reflux Disease or GERD.
Despite the presence of stomach acid, it is possible to suffer from LPR without experiencing any heartburn or GERD symptoms.
Symptoms of Laryngopharyngeal Reflux:
- Continual throat clearing
- Chronic throat irritation or sore throat
- Chronic cough
- Hoarseness / Dysphonia
- Dysphagia (difficulty swallowing)
- A sensation of something in the throat
- Difficulty breathing/Wheezing
Diagnosis of LPR
To diagnose LPR, your ENT specialist will conduct a thorough medical history, evaluate symptoms, and perform a complete physical examination.
Sometimes, additional tests are needed, such as:
