Bronchial asthma is an allergic disease, mainly due to immune dysfunction. Glucocorticosteroids can make the immune function abnormal and should only be used when resuscitating. It should not be used when it is not a rescue, because it will make the immune function abnormal. In fact, the correct treatment is not to use glucocorticosteroids, but to improve, restore and maintain immune function, which can be cured. However, if you are already glucocorticoid dependent, you should not stop glucocorticoids. Stopping glucocorticosteroids will cause a rebound, i.e. the disease will worsen. You should add drugs to improve immune function and, if necessary, add temporary effective non-hormonal anti-allergy drugs to slowly reduce or stop glucocorticosteroids.
