Laryngopharyngeal reflux (LPR) is a condition that can lead to persistent throat irritation and coughing, particularly after consuming heavy meals. According to Dr. Joseph Salhab, a gastroenterologist based in Florida, the symptoms of LPR include chronic throat clearing, a sensation of something lodged in the throat, hoarseness, and a chronic cough. This occurs when hydrochloric acid and the enzyme pepsin from the stomach travel up the esophagus and irritate the sensitive voice box. Standard acid reflux medications may not be effective for LPR. To manage the condition, Dr. Salhab recommends dietary modifications such as avoiding common trigger foods like coffee, alcohol, spicy and acidic foods, as well as chocolate and mint. He also advises against late-night meals and suggests following a low-acid diet. For persistent symptoms, the use of sodium alginate, a natural gum from brown seaweed, may help by creating a protective barrier against stomach acid. If symptoms continue, consulting a gastroenterologist or an ENT specialist is advised. This information is intended for educational purposes and should not replace professional medical advice.
