The Real Causes of Constant Phlegm and Mucus in the Throat — And How to Get Rid of It
Constant mucus or phlegm in the throat can be annoying, but it’s often caused by a common and treatable problem.
Common Causes
1. Postnasal drip
Mucus from the nose can drain into the throat because of allergies, a cold, sinus problems, or irritation.
2. Acid reflux
Stomach acid can irritate the throat and create a feeling of excess mucus or something stuck in the throat.
3. Allergies
Dust, pollen, pets, and other allergens can increase mucus production.
4. Dehydration
Not drinking enough fluids can make mucus thicker and harder to clear.
5. Smoking or air pollution
Smoke and other irritants can inflame the airways and increase mucus.
What Can Help?
- Drink plenty of water.
- Try saline nasal rinses if nasal congestion or allergies are involved.
- Avoid smoking and secondhand smoke.
- If reflux is suspected, avoid large meals close to bedtime.
- Keep your home free from excessive dust and other known allergens.
If mucus lasts for several weeks, keeps getting worse, contains blood, or occurs with breathing difficulty, chest pain, fever, or unexplained weight loss, see a healthcare professional.
Bottom line: Constant phlegm is usually linked to irritation, allergies, postnasal drip, reflux, or another underlying condition. Treating the cause is the best way to reduce it.
