Understand the causes, symptoms, and effective treatments for postnasal drip.
What Is Postnasal Drip?
Postnasal drip is a common condition where excess mucus from the nose and throat glands drips down the back of the throat. This can cause a persistent sensation of mucus in the throat, frequent throat clearing, coughing, and sometimes a sore throat. While usually not serious, postnasal drip can be uncomfortable and disruptive to daily life.

- Sinus infections (sinusitis)
- Environmental irritants (smoke, perfumes, cleaning products)
- Spicy foods
- Pregnancy
- Medications (such as birth control or blood pressure drugs)
- Gastroesophageal reflux disease (GERD)
- Chronic respiratory conditions (like chronic obstructive pulmonary disease)
- Deviated septum
- Nasal polyps
