🤢 The Real Causes of Constant Phlegm and Mucus in Throat — And How to Get Rid of It


 

That thick, sticky feeling in the back of your throat.

The constant need to clear your throat or swallow. The nagging sensation that you’re always “full of mucus.”

If you're dealing with chronic phlegm or postnasal drip, you’re not alone — and it’s more than just a minor annoyance.

While occasional mucus is normal (it protects your airways), persistent buildup can disrupt sleep, cause coughing, and even lead to sore throats or bad breath.

Let’s explore the real medical causes behind constant throat mucus — and what actually works to reduce it — so you can breathe easier, speak clearly, and stop swallowing discomfort all day long.

Because real relief isn’t about suppressing symptoms. It’s about finding the root cause — and treating it wisely.

🔍 What Is Phlegm? (And Why Your Body Makes It)

✅Mucus
Clear, slippery fluid produced by mucous membranes (nose, sinuses, lungs) — keeps tissues moist and traps irritants
✅Phlegm
Thick mucus expelled from the lower airways (throat, lungs) — often discolored when infected

Your body produces about 1–1.5 liters of mucus daily — most of which you swallow without noticing.

But when production increases or drainage slows, you feel that familiar globus sensation — like something’s stuck in your throat.
