Bronchial asthma is a chronic inflammatory disease of the airways, and there is a lack of a complete clinical cure. The treatment time of bronchial asthma varies from person to person and is related to the severity of the patient’s condition and whether the treatment is standardized. Generally speaking, through 2-3 years of standardized medication, most patients can effectively control their symptoms, or even achieve complete remission and return to normal life, work and study. If patients reduce or stop the medication at will during the treatment process, they may not reach a state of complete remission even after decades of treatment.
