Prevalence rates of nasal polyps in the general adult population are likely to be between 2% and 4%; about 7% of people with asthma also have chronic rhinosinusitis with nasal polyps.[3]Langdon C, Mullol J. Nasal polyps in patients with asthma: prevalence, impact, and management challenges. J Asthma Allergy. 2016 Mar 14;9:45-53.

Chronic sinusitis affects 5% to 12% of the general population.[2]Fokkens WJ, Lund VJ, Hopkins C, et al. European position paper on rhinosinusitis and nasal polyps 2020. Rhinology. 2020 Feb 20;58(suppl s29):1-464.

Nasal polyps are present in approximately 25% to 30% of patients with chronic rhinosinusitis.[5]Stevens WW, Schleimer RP, Kern RC. Chronic rhinosinusitis with nasal polyps. J Allergy Clin Immunol Pract. 2016 Jul-Aug;4(4):565-72.

Nasal polyps are more common in men than in women. The average age of onset is approximately 42 years.[5]Stevens WW, Schleimer RP, Kern RC. Chronic rhinosinusitis with nasal polyps. J Allergy Clin Immunol Pract. 2016 Jul-Aug;4(4):565-72.

They are less commonly found in those ages <18 years.[4]Rank MA, Chu DK, Bognanni A, et al. The Joint Task Force on Practice Parameters GRADE guidelines for the medical management of chronic rhinosinusitis with nasal polyposis. J Allergy Clin Immunol. 2023 Feb;151(2):386-98.

A higher prevalence is found in people with asthma, people with cystic fibrosis, and people with aspirin- or nonsteroidal anti-inflammatory drug-hypersensitivity, compared with the general population.[3]Langdon C, Mullol J.
