Nasal polyps (NP) are non cancerous growths within the nose or sinuses. Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. The growths are sac-like, movable, and nontender. They typically occur in both nostrils in those who are affected. Face pain may occasionally occur. Complications may include sinusitis.

The exact cause is unclear. They occur more commonly among people who have allergies, cystic fibrosis, aspirin sensitivity, or certain infections. They are overgrowths of the mucous membranes. Diagnosis may occur by looking up the nose and a CT scan may be used to help plan treatment.

Treatment is typically with steroids, often in the form of a nasal spray. If this is not effective surgery may be considered. The condition may recur following surgery. Antihistamines may help with symptoms but do not change the underlying disease. Antibiotics are not required unless complications occur. About 4% of people currently have nasal polyps while up to 40% of people develop them at some point in their life. They most often occur after the age of 20 and are more frequent in males than females.

Nasal polyps are usually classified into antrochoanal polyps and ethmoidal polyps. Antrochoanal polyps arise from the maxillary sinuses and are the much less common; ethmoidal polyps arise from the ethmoidal sinuses.
