→ Constant throat irritation
→ Improves when away from smoke/pollution

⚠️ Less common for chronic mucus
→ Acute onset (days)
→ Colored mucus + fever
→ Resolves within 10–14 days
💡 Critical correction: While viral posts claim "acid reflux is the #1 undiagnosed cause," allergies and chronic sinus inflammation are actually more prevalent for persistent throat mucus. LPR is important—but not the universal culprit.
⚠️ Understanding LPR ("Silent Reflux") — Without the Hype:⚠️ Understanding LPR ("Silent Reflux") — Without the Hype
What it is: Stomach contents (acid and pepsin enzymes) reflux into the throat/larynx—without typical heartburn. The throat lacks the esophagus's protective lining, so even small amounts cause irritation → excess mucus production as a defense mechanism.
Why it's missed:
❌ No chest burning (unlike GERD)
❌ Symptoms mimic allergies ("post-nasal drip")
❌ Doctors may not ask about throat clearing/hoarseness
Diagnosis: Often clinical (based on symptoms + trial of treatment). pH monitoring or ENT scope can confirm—but not always necessary.

Why It Works
Evidence Level
Nasal saline irrigation (Neti pot)
Flushes allergens/inflammatory mediators from sinuses
✅ Strong (recommended by ENTs)
Intranasal corticosteroids (Flonase)
Reduces sinus inflammation at the source
✅ Strong (first-line treatment)
Antihistamines (loratadine, cetirizine)
Blocks histamine-driven mucus production
