There is no such thing as the most feared nemesis of asthma, but it is necessary to avoid exposure to allergens and standardize medication management.
The triggers of asthma are exposure to domestic pets, pollen, paint or allergenic food, allergic drugs such as aspirin, etc. The body cannot tolerate the stimulation triggered by these allergens and thus develops an allergic reaction, which leads to bronchial spasm, constriction, and expiratory dyspnea, i.e., asthma.
After identifying the allergens, minimize the exposure to the allergens to avoid asthma triggers, and at the same time carry out long-term standardized treatment, most patients can achieve good or complete clinical control, i.e., based on the use of the smallest effective dose of medication or no medication, can make the patient and the same as a normal person to live, study and work.
