Nasal polyps

Also called Chronic rhinosinusitis with nasal polyps

Nasal polyps are soft, harmless growths that develop inside the nose and sinuses. They are linked to long-term inflammation, and are more common in adults with asthma or sensitivity to aspirin. Small polyps may cause no symptoms, but larger ones can block the nose and reduce the sense of smell.

What it is

Steroid nasal sprays or drops can shrink them, and steroid tablets are sometimes used for short periods. Rinsing the nose with salt water helps.

Surgery can remove large polyps, but they can come back. Newer biologic medicines may help some people with severe polyps.

  • A blocked nose
  • A runny nose
  • Mucus running down the back of the throat

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Treatments tried and their effect

Questions to ask your doctor

  • How should I use the nasal spray or drops?
  • Do I need surgery?
  • Is this linked to my asthma?
