How does rhinitis arise?

Rhinitis may be caused by genetic factors, environmental factors, exposure to allergens, infectious factors, etc.

1. Genetic factors

If there are rhinitis patients in the family, then the individual risk of rhinitis may increase, which may be related to specific genetic factors.

2. Environmental factors

Air pollution, such as particulate matter in the air, chemical pollutants, etc., long-term exposure may irritate the nasal mucosa, leading to rhinitis. Climate change is also one of the important factors. Rapid changes in temperature and humidity may affect the normal function of the nasal mucosa.

3. Exposure to allergens

Common allergens such as pollen, dust mites, animal dander, etc., when the human body is exposed to these allergens, the immune system will produce an excessive reaction, causing allergic rhinitis.

4. Infectious factors

Virus, bacteria and other infections can cause inflammation of the nasal mucosa, especially after upper respiratory tract infections such as colds, if the treatment is not timely or thorough, may induce rhinitis.
