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

That annoying throat-clearing sensation? Here’s what’s really going on — and what to do about it.

Do you constantly feel like there’s something stuck in your throat? Are you always clearing your throat, coughing up mucus, or dealing with post-nasal drip? If so, you’re not alone. Excess phlegm or mucus in the throat is a common (and frustrating) issue — but it’s also your body’s way of telling you something isn’t right.

Let’s break down why it happens, what causes it, and most importantly, how to get rid of it.


🤔 What’s the Difference Between Phlegm and Mucus?

  • Mucus is a thin, slippery fluid produced by the lining of your nose, throat, and airways to trap dust, bacteria, and allergens.
  • Phlegm is a type of mucus that’s thicker and typically comes from your lungs and lower airways, especially when you’re sick or congested.

When you feel like something is stuck in your throat, it’s usually mucus or post-nasal drip — not phlegm from your lungs.


⚠️ Common Causes of Constant Mucus in the Throat

1. Post-Nasal Drip

  • When your sinuses produce too much mucus, it drips down the back of your throat.
  • Causes: Allergies, sinus infections, cold weather, dry air, dust, or irritants.
  • Symptoms: Constant throat clearing, coughing, and a “tickle” in the throat.

2. Allergies

  • Pollen, pet dander, mold, or dust mites can trigger mucus overproduction.
  • Often worse in spring and fall or when indoors with poor air quality.

3. Acid Reflux (GERD or LPR)

  • Stomach acid travels up into the esophagus and irritates the throat lining.
  • Symptoms: Mucus in throat, sore throat, cough, or a lump sensation (globus).

4. Viral or Bacterial Infections

  • Colds, flu, sinus infections, and bronchitis increase mucus production.
  • Mucus may become thicker or change color when infection is present.

5. Smoking or Exposure to Smoke

  • Smoke irritates the airways and causes chronic mucus production.
  • This includes cigarettes, vapes, and even secondhand smoke.

6. Dehydration

  • Not drinking enough water can make your mucus thick and sticky.
  • Thick mucus is harder to swallow and more likely to linger.

7. Food Sensitivities or Dairy Intake

  • Some people are sensitive to dairy or other foods that may trigger more mucus.
  • Not scientifically proven for everyone — but worth testing if you notice a link.
