Ep. 276 LPR vs. LPS: Key Differences & Diagnostic Techniques with Dr. Inna Husain
Description
Not all chronic cough, globus, or voice changes are due to reflux, so how do you distinguish laryngopharyngeal symptoms (LPS) from true laryngopharyngeal reflux disease (LPRD)? In this episode of the BackTable ENT & Allergy podcast, Dr. Ashley Agan interviews laryngologist Dr. Inna Husain about how nuanced diagnostic definitions and a careful clinical approach can improve patient outcomes and avoid both under- and overdiagnosis. Together, they discuss the differences between GERD and LPRD, review the importance of detailed patient histories, endoscopic findings, and the evolving role of biomarkers like pepsin.
