Persistent coughing and throat irritation experienced after heavy meals are frequently symptoms of laryngopharyngeal reflux (LPR) or acid reflux, rather than solely respiratory infections. This insight comes from Dr. Joseph Salhab, a Florida gastroenterologist, as highlighted in a Hindustan Times article. LPR, often termed 'silent reflux,' occurs when stomach acid and pepsin travel up the esophagus to irritate the sensitive voice box and throat, triggering symptoms even without the classic heartburn associated with GERD (Gastroesophageal Reflux Disease). Key symptoms of LPR include a chronic cough that persists, particularly after eating, constant throat clearing, a feeling of something being stuck in the throat (globus sensation), and hoarseness of voice. Medical experts corroborate that acid reflux and LPR are significant causes of post-meal coughing, differentiating them from common colds or flu. Treatment primarily focuses on reducing irritation and reflux exposure through lifestyle and dietary modifications. Recommended changes include avoiding common trigger foods such as coffee, alcohol, spicy foods, acidic foods, chocolate, and mint. It is also advised to avoid late-night meals, adopt a low-acid diet, and consider natural remedies like sodium alginate suspensions, which form a protective barrier over stomach acid. For persistent or unresolving symptoms, medical evaluation by both a gastroenterologist and an ENT (Ear, Nose, and Throat) physician is strongly recommended for proper diagnosis and a tailored treatment plan.
