Nasal polyp is a kind of benign tumor, a superfluous organism growing inside the nose, nasal polyp is a common disease of the nose, mostly seen in adults, and the causes of its pathogenesis are diverse.
1, chronic inflammatory stimulation: mostly seen in patients suffering from chronic rhinitis, sinusitis, due to long-term chronic inflammatory stimulation of the nasal mucosa, as well as long-term stimulation of the sinuses by purulent secretions, easily caused by congestion, swelling, venous stasis, increased exudation of the nasal mucosa, coupled with the role of bacterial toxins, also contributed to increased exudation, mucosal edema, over time, will cause nasal polyps. In addition, the internal cilia and mucous membrane of the nose has a role in blocking foreign bacteria or dust, and some recessive genetic diseases, such as immobile cilia syndrome, cystic fibrosis and other diseases can lead to the internal cilia and mucous membrane dysfunction, which can not resist and remove foreign bacteria, which can cause repeated infections of the nasal mucosa and nasal polyps in the long run.
2, allergic reaction: allergic reaction refers to the immune system to some substances that are not harmful to the body such as pollen, fur, dust, etc. too sensitive, thus causing the body to immune response and harm the body, there is research to prove that patients suffering from allergic rhinitis or bronchial asthma, prone to nasal polyps.
In addition, the occurrence of nasal polyps may also be related to infection, cytokine action, abnormal gene expression, etc.
