1. Postnasal Drip
One of the most common causes is postnasal drip.
Instead of flowing normally through the nose, excess mucus slowly drips down the back of the throat.
Common triggers include:
- Seasonal allergies
- Colds
- Sinus infections
- Dust
- Dry air
Symptoms
- Constant throat clearing
- Feeling mucus stuck in the throat
- Tickling sensation
- Frequent coughing
What may help
- Saline nasal rinses
- Treating allergies if present
- Staying hydrated
- Using a humidifier if indoor air is dry
2. Acid Reflux (GERD or Silent Reflux)

Many people with chronic throat mucus don’t experience heartburn.
Instead, stomach acid reaches the throat, irritating the tissues and causing the body to produce extra mucus.
This is sometimes called silent reflux (LPR).
Other symptoms include:
- Hoarseness
- Chronic throat clearing
- Lump-in-the-throat sensation
- Frequent coughing
- Sour taste in the mouth
What may help
- Avoid eating large meals before bedtime.
- Limit spicy, fatty, or acidic foods if they trigger symptoms.
- Sleep with your head slightly elevated.
- Speak with your healthcare provider if symptoms persist.
