Postnasal Drip

Postnasal drip, also known as upper airway secretion syndrome or postnasal discharge, is a condition characterized by the sensation of mucus running down the back of the throat.

Causes

• Allergies: Allergic reactions to dust, pollen, pet dander, and mold can cause increased mucus production, leading to postnasal drip.
• Cold and flu: Viral infections such as the common cold and influenza can cause inflammation and increased mucus production in the nasal passages.
• Sinusitis: Inflammation or infection of the sinuses can cause excess mucus production, which can lead to postnasal drip.
• Environmental factors: Exposure to pollution, tobacco smoke, and changes in humidity can irritate the nasal passages and cause increased mucus production.
• Anatomical issues: Deviated septum, nasal polyps, or other structural abnormalities in the nose can contribute to postnasal drip.

Symptoms

• Sensation of mucus running down the back of the throat
• Coughing, especially at night
• Sore throat
• Hoarseness
• Bad breath
• Nasal congestion
• Sneezing and runny nose

Diagnosis

Diagnosis of postnasal drip is typically based on a physical examination, medical history, and symptoms. A healthcare provider may perform a:

• Nasal endoscopy to visualize the nasal passages and sinuses
• CT scan or MRI to evaluate the sinuses and rule out other conditions
• Allergy testing to identify potential allergens

Treatment

Treatment for postnasal drip depends on the underlying cause. Common treatments include:

• Antihistamines and decongestants to relieve allergy symptoms and reduce nasal congestion
• Nasal saline irrigations to moisturize the nasal passages and thin out mucus
• Expectorants to help loosen and clear mucus from the airways
• Corticosteroids to reduce inflammation in the nasal passages and sinuses
• Antibiotics if a bacterial infection is present

Home Remedies

In addition to medical treatment, several home remedies can help alleviate postnasal drip symptoms:

• Staying hydrated by drinking plenty of fluids
• Using a humidifier to add moisture to the air
• Avoiding irritants such as tobacco smoke and pollution
• Elevating the head while sleeping to reduce congestion
• Trying steam inhalation or a neti pot to loosen mucus
