The Real Causes of Constant Phlegm and Mucus in Throat and How to Get Rid of It
That persistent feeling of mucus stuck in your throat, the need to constantly clear your throat, or a nagging post-nasal drip—these aren’t just annoying. They’re signals from your body that something is off balance. While occasional mucus is normal (it protects your airways!), chronic phlegm often points to an underlying trigger.
Here’s a clear, science-backed look at the most common causes—and practical, effective solutions.
🩺 Top 6 Causes of Constant Throat Mucus
1. Post-Nasal Drip (Most Common)
What it is: Excess mucus from the sinuses drips down the back of your throat.
Triggers:
Allergies (pollen, dust, pet dander)
Sinus infections (acute or chronic)
Cold or flu
Weather changes (dry or humid air)
Signs:
Frequent throat clearing
Tickling cough (worse at night)
Nasal congestion or runny nose
✅ Solution:
Saline nasal rinses (Neti pot or spray) 1–2x/day

Nasal steroid sprays (fluticasone) for inflammation
Stay hydrated—thins mucus
