Silent Reflux: A Hidden Cause of Constant Throat Clearing

If you're constantly clearing your throat but don't have a cold or allergies, the cause might be surprising: reflux — even without any heartburn.

What silent reflux is

Laryngopharyngeal reflux (LPR), often called silent reflux, is when stomach contents travel up to the throat and voice box. Unlike classic reflux, it often doesn't cause heartburn, which is why many people never suspect it.

Common signs

Frequent throat clearing.
A feeling of mucus or a lump in the throat.
Hoarseness, especially in the morning.
A chronic, dry cough.
Post-nasal-drip-like sensations.

Why it's worse at night

Lying down makes it easier for stomach contents to travel upward. That's why symptoms are often worst on waking.

Habits that may help: finish eating two to three hours before bed, raise the head of your bed, eat smaller meals, and limit alcohol, fizzy drinks, spicy foods and late-night caffeine.

When to see a doctor

If throat symptoms last several weeks, or you have trouble swallowing, unexplained weight loss or voice changes lasting more than three weeks, see a doctor. An ENT specialist can confirm whether reflux is the cause.
