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.
