Laryngopharyngeal reflux

Laryngopharyngeal reflux

Laryngopharyngeal reflux (LPR) refers to the backflow of stomach contents into the throat. LPR is also called "silent" reflux, because it usually occurs without heartburn, a symptom that is typical of classical gastroesophageal reflux disease (GERD). [http://www.laryngoscope.com/pt/re/laryngoscope/abstract.00005537-199104000-00001.htm;jsessionid=Lr2DKhKTyMyd41JcnPDv1nzzCgdShv1d3TJBs5STMpmQVkDbGfpT!-1124491571!181195628!8091!-1?index=1&database=ppvovft&results=1&count=10&searchid=3&nav=search] The term LPR was coined in 1981 by Dr. Jamie Koufman, a throat specialist. [http://www.medicalnewstoday.com/articles/47561.php]

The symptoms of LPR are hoarseness, postnasal drip, sore throat, difficulty swallowing and chronic coughing, and throat clearing. The prevalence of LPR is unknown; however, cough, hoarseness, and post-nasal drip are among the most common symptoms for which people seek medical attention. LPR is still considered somewhat controversial because there is no gold standard test for its diagnosis.

Treatment of LPR usually requires modification of diet, including avoidance of caffeine, fatty foods, carbonated beverages, and chocolate. Smoking should also be avoided. Antireflux medications are also commonly used. [http://www.otojournal.org/article/S0194-5998(02)00046-3/abstract]

LPR symptoms may result in an inaccurate diagnosis of allergy, sinusitis, asthma, or an anaphylactic allergic reaction. LPR is usually treated by an Ear, Nose and Throat specialist.
