Silent Reflux (LPR): The Reflux That Has No Heartburn
Silent reflux, or LPR, is acid reflux that skips the heartburn and instead irritates your throat and voice box. Tell-tale signs: a chronic cough, hoarseness, constant throat-clearing, or a lump-in-the-throat feeling. It's commonly mistaken for allergies or a lingering cold. Diet tweaks, posture and timing of meals usually help.
You don't have heartburn, so reflux isn't on your radar — yet you've had a nagging cough, a hoarse voice, or the constant urge to clear your throat for months. This is the frustrating reality of laryngopharyngeal reflux (LPR), often called silent reflux.
Why it's 'silent'
In classic reflux, acid rises into the oesophagus and burns. In LPR, small amounts of acid and digestive enzymes travel higher — up to the throat and voice box — where there's no burning sensation but plenty of irritation. That's why the symptoms show up far from your stomach.
Signs to watch for
- Chronic dry cough, especially after eating or lying down
- Hoarseness or a voice that tires easily
- Frequent throat-clearing
- A persistent lump-in-the-throat sensation (globus)
- Post-nasal drip feeling, mild sore throat, or trouble swallowing
How to calm silent reflux
- Don't eat within 3 hours of lying down — this is the single biggest lever.
- Raise the head of your bed slightly.
- Trim common triggers: large late meals, fried/fatty foods, alcohol, caffeine and very acidic foods.
- Eat smaller, slower meals and stay upright afterwards.
Key takeaways
- LPR is reflux without heartburn — it irritates the throat and voice.
- Chronic cough, hoarseness and a throat lump are key clues.
- Not eating 3 hours before bed is the most effective fix.
- Persistent hoarseness or swallowing trouble needs a doctor.
