What Causes Nasal Polyps?

Nasal polyps are painless, noncancerous growths on the lining of your nasal passages or sinuses. They often result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity, or certain immune disorders. Understanding these causes is important for effective treatment.

How Nasal Polyps Are Treated

Treatment usually starts with medication aimed at the inflammation causing the polyps rather than at the polyps themselves. Nasal steroid sprays and rinses are typically tried first, sometimes alongside a short course of oral steroids. Polyps often shrink with treatment, and medication is usually tried before surgery is considered.

Polyps frequently sit alongside allergies or asthma. Addressing those can change how quickly polyps return — see our allergy testing and treatment.

Surgery is generally considered when polyps do not respond to medication or when they block the airway significantly. Polyps can return after treatment, which is why ongoing management of the underlying inflammation matters as much as the initial treatment.

Managing allergies and asthma, using saline nasal rinses, and avoiding nasal irritants can also help prevent polyp growth. Your provider will go through the options and their risks with you. Individual results vary.

When to Seek Medical Attention

If you're experiencing persistent symptoms or complications from nasal polyps, it's important to seek medical attention. Untreated polyps can lead to worsening symptoms and complications.

Polyps share symptoms with loss of smell and nasal obstruction — worth a look if either sounds familiar too.
