Nasal Polyps


Nasal polyps are noncancerous growths that are caused by long term swelling of the inside of your nose. The swelling may be the result of allergies, or repeated nasal or sinus infections. Polyps usually occur in both sides of your nose. They can grow in size and number which may cause your nasal tissue and bone to expand. Polyps can also grow large enough to block air going in and out of your nose.


Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
