Nasal Polyps (Medical Definition) | Quick Explainer Video

Nasal polyps are noncancerous growths that develop in the lining of the nose or sinuses. These soft, painless swellings are usually caused by chronic inflammation in the nasal passages, which can be triggered by conditions such as allergies, asthma, or recurring infections. Nasal polyps can cause symptoms such as a blocked or runny nose, reduced sense of smell, facial pain or pressure, and snoring. Treatment options for nasal polyps may include medications to reduce inflammation, nasal sprays, or in some cases, surgery to remove the polyps. Regular monitoring and management of underlying conditions can help prevent the recurrence of nasal polyps.
