Nasal Polyps

Nasal Polyps 1024x681

Nasal polyps are soft, noncancerous growths that form inside the nasal passages or sinuses. They often develop as a result of long-term inflammation and can interfere with normal breathing, smell, and sinus drainage. Although nasal polyps can occur at any age, they are more common in adults and frequently affect individuals with asthma, chronic sinus infections, or allergies.

With proper evaluation and treatment, nasal polyps can be effectively managed to reduce symptoms, prevent complications, and improve overall quality of life.

What causes nasal polyps

Nasal polyps develop when ongoing inflammation causes the tissue lining the nose and sinuses to swell. Over time, this swelling leads to fluid buildup and polyp formation.

Common conditions associated with nasal polyps include:

  • Chronic sinus infections (chronic rhinosinusitis)

  • Allergic rhinitis (hay fever)

  • Asthma

  • Aspirin sensitivity

  • Recurrent respiratory infections

  • Immune system disorders

  • Cystic fibrosis (in some patients)


While the exact cause isn’t always clear, nasal polyps are more likely to develop in people with long-standing nasal or sinus inflammation.

What symptoms are associated with nasal polyps

Symptoms often develop gradually and may worsen over time as polyps grow larger. Many patients mistake nasal polyps for a lingering cold or sinus infection.

Common symptoms include:

  • Persistent nasal congestion or stuffiness

  • Difficulty breathing through the nose

  • Runny nose or postnasal drip

  • Reduced or complete loss of smell and taste

  • Facial pressure or fullness

  • Headaches or sinus pain

  • Frequent sinus infections

  • Snoring or mouth breathing


If left untreated, nasal polyps can increase the risk of repeated sinus infections and significantly impact daily comfort and sleep quality.

Diagnosis of nasal polyps

Diagnosis begins with a detailed medical history and physical examination of the nose and sinuses. Your provider may use specialized tools to confirm the presence and size of nasal polyps.

Diagnostic methods may include:

  • Nasal endoscopy: A thin, flexible camera allows direct visualization of the nasal passages and sinuses

  • Imaging studies: CT scans help determine the extent of polyp growth and sinus blockage

  • Allergy testing: Identifies underlying allergic triggers that may contribute to inflammation

  • Asthma or immune evaluation: When symptoms suggest related conditions


An accurate diagnosis is essential for creating an effective and personalized treatment plan.

How are nasal polyps treated?

Treatment focuses on reducing inflammation, shrinking polyps, relieving symptoms, and preventing recurrence. The approach depends on the size of the polyps, symptom severity, and underlying conditions.

Medical treatment options may include:

  • Nasal corticosteroid sprays to reduce inflammation

  • Short courses of oral corticosteroids for severe symptoms

  • Saline nasal rinses to improve drainage

  • Allergy management to control triggers

  • Biologic medications for patients with severe or recurrent polyps


Surgical treatment

If medications do not adequately control symptoms, minimally invasive sinus surgery may be recommended. Surgery removes polyps and improves sinus drainage but is often combined with ongoing medical therapy to reduce the risk of recurrence.

Can nasal polyps come back?

Yes, nasal polyps can recur, especially in patients with chronic inflammation, asthma, or allergies. Long-term management is key and may include regular follow-ups, daily nasal sprays, and treatment of underlying conditions.

Consistent care significantly reduces symptom flare-ups and improves long-term outcomes.
