Bronchial asthma is not well treated and can only be treated in a controlled manner. First of all, bronchial asthma is a chronic inflammatory disease of the airways caused by a variety of complex factors, and bronchial asthma is characterized by difficulty in eradication and recurrent attacks. At present, the causes of bronchial asthma can be broadly divided into two types: genetic factors and environmental factors. Genetic causes are mostly closely related to the phenomenon of low immunity, allergic constitution and airway hyperresponsiveness of patients. Environmental factors, on the other hand, mainly include food allergy, micro-particle allergy, drug allergy, etc. And for bronchial asthma caused by environmental factors, the most effective treatment can generally only be taken in the form of controlled remission and preventive measures to exclude the triggering factors.
