Quick Scoop: What are nasal polyps?

Nasal polyps are soft, noncancerous growths that form in the lining of the nose or sinuses. They’re usually linked to long-term inflammation and can cause stuffiness, reduced smell, and breathing trouble if they get large enough.

Key points

  • They are benign growths, not cancer.
    • [7][1]
  • Small polyps may cause no symptoms at all.
    • [1][7]
  • Common symptoms include a blocked or runny nose, postnasal drip, facial pressure, snoring, and loss of smell or taste.
    • [2][7][1]
  • They’re often associated with chronic sinus inflammation, asthma, allergies, or repeat infections.
    • [4][10][7]
  • Treatment often starts with steroid nasal sprays and saline rinses; some people need oral medicines, biologics, or surgery.

When to get checked

If nasal congestion lasts for weeks, smell gets noticeably weaker, or you keep getting sinus problems, it’s worth seeing a clinician. Persistent symptoms can overlap with other sinus or allergy conditions, so an exam helps confirm what’s going on.

TL;DR: Nasal polyps are benign, inflammation-related growths inside the nose/sinuses that can block airflow and cause chronic congestion, reduced smell, and sinus pressure.
