Complications

Nasal polyps can cause complications because they block normal airflow and fluid drainage, and also because of the long-term irritation and swelling (inflammation) underlying their development.

Potential complications include:

• Obstructive sleep apnea. This is a potentially serious condition in which you stop and start breathing frequently during sleep.
• Asthma flare-ups. Chronic sinusitis can worsen asthma.
• Sinus infections. Nasal polyps can make you more susceptible to sinus infections that recur often.
