Postnasal Drip Causes, Symptoms, And Treatments Guide

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.

• Allergic rhinitis (hay fever)
• Colds and flu
• 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

Diagnosis of Postnasal Drip

Diagnosing postnasal drip typically involves a review of symptoms and medical history. A healthcare provider may perform a physical examination and, in some cases, order additional tests to identify the underlying cause. These tests may include:

Surgical Options
