Reflux and Hoarseness: Clinical Evidence and Guidelines

Key Evidence on Reflux and Hoarseness

The American Academy of Otolaryngology-Head and Neck Surgery states that not all patients with reflux have dysphonia, highlighting the need for careful evaluation of patients with suspected laryngopharyngeal reflux 1, 2

Hoarseness was present in 0% of gastroenterology patients with GERD, demonstrating that typical reflux primarily manifests with gastrointestinal symptoms, not laryngeal ones 3
Heartburn and regurgitation are present in 89% of gastroenterology patients with GERD, though extraesophageal manifestations can occur without GI symptoms in up to 75% of cases 4

The presence or absence of hoarseness does not confirm or exclude reflux disease, and clinicians should consider laryngoscopy findings and other symptoms when evaluating patients with suspected laryngopharyngeal reflux 1, 2
Laryngoscopy findings, such as erythema, edema, and surface irregularities, are more relevant than symptom presence alone in diagnosing reflux-related laryngeal disease 5, 6

Clinicians should not prescribe anti-reflux medications for patients with hoarseness without signs or symptoms of gastroesophageal reflux disease, due to the unclear benefit and potential risks of treatment 5, 6
The American Academy of Otolaryngology-Head and Neck Surgery recommends that clinicians may prescribe anti-reflux medication for patients with hoarseness and signs of chronic laryngitis on laryngoscopy 5, 6
PPI use carries risks, including decreased calcium absorption, increased hip fracture risk, vitamin B12 deficiency, and iron deficiency anemia 5, 6, 7
