What is generally considered a common cause of nasal polyps?

Chronic inflammation is widely acknowledged as a primary cause of nasal polyps. These growths, which are soft, painless, noncancerous lesions, frequently develop in the nasal passages or sinuses resulting from prolonged inflammation of the mucous membranes. Conditions such as asthma, recurrent sinus infections, cystic fibrosis, and certain immune disorders frequently lead to chronic inflammation, thereby increasing the likelihood of nasal polyp development.

While other factors like fungal infections, genetic predisposition, and allergic responses can contribute to the presence of nasal polyps, they are generally seen as secondary or additional factors rather than the primary cause. Chronic inflammation stands out due to its direct role in the pathological processes of the nasal mucosa, making it the most significant factor to consider when understanding the etiology of nasal polyps.
