Constant phlegm in your throat usually isn’t random—it’s your body reacting to something. The tricky part is figuring out what.
Here are the most common causes:
1. Post-nasal drip (most common)
Your nose and sinuses produce mucus that drips down your throat, especially when lying down. This often comes from:
- Allergies (dust, pollen, pets)
- Sinus infections
- Weather changes
2. Acid reflux (Gastroesophageal Reflux Disease)
Stomach acid can travel up and irritate your throat, causing a constant need to clear it—even without heartburn.
3. Infections
Recent colds, flu, or even mild lingering infections can leave excess mucus behind for weeks.
4. Smoking or air irritation
Smoke, pollution, or strong chemicals can trigger mucus production.
5. Dehydration
Not drinking enough water makes mucus thicker and more noticeable.
6. Certain foods
Dairy doesn’t create mucus for everyone, but for some people it can make it feel thicker.
What you can try
- Drink more warm fluids (water, tea)
- Use steam inhalation
- Try saline nasal rinses
- Avoid triggers (dust, smoke, cold drinks if sensitive)
- Elevate your head while sleeping
When to take it seriously
See a doctor if you have:
- Symptoms lasting more than 3–4 weeks
- Blood in mucus
- Trouble swallowing or breathing
- Unexplained weight loss
- Severe throat pain
If you want, tell me:
- How long you’ve had it
- Any other symptoms (cough, heartburn, allergies, etc.)
I can help narrow it down more precisely.
