summary

Asthma is a kind of frequently occurring disease. There are many patients with asthma around us, and many patients with asthma lose their lives because they can not get timely treatment. There are many reasons leading to asthma. What are the reasons for adult asthma? Now let me tell you something.

What is the cause of adult asthma?

Genetic factors can be reflected in many patients, such as the vast majority of patients' relatives (blood relationship, nearly three generations) can be traced back to the history of asthma (repeated cough, wheezing) or other allergic diseases (allergic rhinitis, atopic dermatitis).

Environmental factors most asthma patients are allergic constitution, they may have allergic rhinitis and / or atopic dermatitis, or allergic to common airborne allergens (mites, pollen, pets, molds, etc.), some foods (nuts, milk, peanuts, seafood, etc.), drugs, etc.

The change of air humidity also has an impact on the incidence of asthma. Too high or too low humidity is unfavorable for children. The most appropriate relative humidity is 60% - 70%. On the one hand, too high humidity can affect the evaporation of water on the body surface. In order to promote the discharge of water, the human body can only compensate by accelerating the respiratory rate. As a result, it increases the resistance of the airway and easily induces asthma. On the other hand, too high humidity can promote the reproduction of bacteria, which is conducive to the breeding of dust mites. These pathogenic microorganisms can easily induce asthma after invading the airway. Viral or bacterial infections can make asthma attacks more difficult to control. On the contrary, when the humidity is too low, it can make the airway mucosa dry, airway epithelial cells damage, epithelial surface cilia movement disorder, affect the airway expectoration function, also can aggravate the disease.
