Nasal polyps are noncancerous growths that form in the lining of the nasal and sinus passages. They are normally soft and shaped like teardrops or grapes. There is typically no pain associated with nasal polyps. Long-term inflammation is usually the cause of nasal polyps. We review more about the connection between allergies, asthma and nasal polyps below.
What Does the Research Show?
One 2021 study found, “A correlation between the presence of nasal polyps and asthma, as well as allergic and non-allergic rhinitis The greatest risk factor for [nasal polyps] in the evaluated subpopulation with multiple allergic conditions was the co-existence of non-allergic rhinitis and atopic dermatitis.”
Why the Link?
Experts theorize that the reason there’s a link between allergic conditions, including asthma, and nasal polyps is because these conditions cause chronic inflammation of the nasal and sinus passages. In addition, damaged nasal and sinus tissue can increase your exposure to airborne irritants, leading to nasal polyps.
