What are Nasal Polyps?
What is going on in the body?
The nose acts as a filter, removing over 80% of particles in the air. A variety of agents entering the nose can cause inflammation. These agents include pollens, mold spores, animal dander, dust mites, dust, and dirt. Nasal polyps are the result of long-term, untreated nasal inflammation. Rarely, the polyps may protrude through the nostrils.
What are the causes and risks of the condition?
Many disorders can lead to nasal polyps, including:
- asthma, a disease of the airways that is the most common cause
- chronic allergies
- sinusitis, particularly sinus infections cause by a fungus
- cystic fibrosis, a congenital disease that affects the airways
- sensitivity to aspirin
- structural abnormalities of the nose
