Chronic Cough, Throat Clearing, or Voice Changes? It Might Not Be Reflux. Here's How to Tell
If you've been dealing with a nagging cough, a constant urge to clear your throat, a lump-in-the-throat feeling (doctors call this "globus"), or a voice that sounds hoarse for no clear reason, there's a good chance someone (a doctor, a friend, the internet) has told you it's "probably reflux."
Sometimes that's true. Sometimes it's not. And knowing the difference matters more than most people realize.
Two Different Things, One Easy Mix-Up
Throat and airway symptoms like chronic cough, throat clearing, globus, and voice changes are often lumped together under one umbrella: "silent reflux." But a major new clinical framework called the San Diego Consensus draws a clearer line between two related, but distinct, things.
Laryngopharyngeal symptoms (LPS) are simply symptoms, like cough, throat clearing, voice changes, or that lump-in-the-throat feeling, that could be caused by reflux, but could also be caused by allergies, postnasal drip, vocal strain, certain medications, or something else entirely.
Laryngopharyngeal reflux (LPR) is what's actually happening when those symptoms are caused by reflux, meaning there's objective evidence that stomach contents are reaching the throat and airway.
The big takeaway: having LPS doesn't automatically mean you have LPR. They overlap, but they're not the same thing, and treating one as the other is where things tend to go sideways.
Why It Matters
Lump every chronic cough or hoarse voice into "it's reflux," and two things can happen. Someone whose symptoms are actually driven by allergies or vocal strain ends up on reflux medication that doesn't touch the real problem. Or someone who does have reflux-driven symptoms gets a quick prescription without ever being properly evaluated, so the real plan for managing it long-term never gets built.
This is exactly the territory our VP of Education, Dr. Inna Husain, a laryngologist specializing in voice and airway disorders, delved into on a recent episode of the BackTable ENT & Allergy Podcast with Dr. Ashley Agan.
Inside the Episode
Dr. Husain and Dr. Agan get into the details clinicians are actively debating right now, including:
Test vs. treat. When does it make sense to actually test for reflux using tools like 24-hour pH-impedance or wireless pH monitoring, rather than starting with an empiric treatment trial?
Pepsin as a biomarker. Pepsin is a digestive enzyme that shouldn't be in your throat. When it shows up there, what does that actually tell us, and how reliable is testing for it?
Tapering off PPIs. Proton pump inhibitors aren't meant to be a forever fix for everyone. What does a safe taper look like, and where do alginates fit into that transition?
GLP-1s and reflux. With GLP-1 medications more common than ever, what's the early evidence saying about their effect on reflux symptoms?
Worth Your Time
If you've been told your chronic cough, throat clearing, globus, or voice changes are "just reflux," or if you've tried reflux medication without much relief, this LPS-versus-LPR distinction might be exactly why. Dr. Husain and Dr. Agan unpack it all with the kind of nuance you won't get from a quick Google search, and it's a genuinely fascinating listen whether you're a patient trying to make sense of your symptoms or a clinician refining your approach.
