Nasal polyps are associated with inflammation of the lining of the nasal passages or sinuses that last more than 12 weeks. The nasal polyps are soft and painless, and they hang down like teardrops or grapes.
Small nasal polyps may not cause symptoms; however, large nasal polyps can block your nasal packages leading to breathing problems, a loss of sense of smell, and frequent sinus infections.
Nasal polyps usually occur in adults. The goal of treatment is to reduce the size or eliminate the nasal polyps. Medications can be effective at shrinking or eliminating nasal polyps, but surgery is sometimes needed to remove the polyps. It is not uncommon for nasal polyps to return.
