Dry Throat: Eleven Causes From Mouth-Breathing to Medication, and What Helps Each

A persistently dry throat is more often a habit or an environment than an illness. Here are the common causes, how to tell them apart, the fixes with evidence and the signs that need a doctor.

Habit and Environment

Mouth-breathing, awake or asleep, is the commonest cause: the nose humidifies air and the mouth does not. Dry indoor air from heating or air conditioning. Dehydration, often from caffeine and alcohol without enough water. Talking or singing for long periods. Dust, smoke and fumes. Each dries the lining directly and each has a direct fix.

Medical Causes

Many medications reduce saliva: antihistamines, decongestants, antidepressants, blood pressure drugs and inhaled steroids, which also predispose to oral thrush. Reflux irritates the throat overnight. Post-nasal drip from allergy or sinus inflammation. Snoring and sleep apnoea. Autoimmune dryness conditions, less common but worth testing for when dryness affects eyes too. Diabetes raises thirst and dryness.

Fixes With Evidence

Nasal breathing, retrained by day and supported at night with nasal strips or treatment of blockage. Humidity at 40–50%. Water through the day, less caffeine and alcohol. Rinsing the mouth after inhaled steroids. Sugar-free lozenges or demulcent sprays to coat the throat. Treating reflux and allergy. Reviewing medication with a doctor if dryness started with a new prescription.

When to See a Doctor

Dryness with difficulty swallowing, a lump sensation, hoarseness over three weeks, sores, white patches, or dryness of the eyes and other tissues. Dryness that began with a medication. Persistent throat symptoms in a smoker. A soothing routine helps the sensation; these signs need the cause found.
