Many patients with asthma are seen in the clinic and are often asked the above questions. In fact, asthma is a chronic inflammatory airway disease characterized by airway hyperresponsiveness (airway hyperresponsiveness is an easy reaction of the airways to external stimuli such as smoke, dust, irritating odors, allergens, etc. The reaction can be manifested as irritating cough, airway spasm, etc.), with a tendency to gather in families, and the clinical manifestations are recurrent episodes of chest tightness and wheezing. There is no cure (because it is the environment through the genes that eventually develop, and genes are inherited), what doctors can do is to clinically control and reduce the risk of attacks, and as long as the clinical control is complete, it can be the same as normal people. Some patients are frustrated to hear that there is no cure, but in fact, many medical diseases cannot be cured, but can only be clinically controlled or stabilized, such as hypertension and diabetes mellitus, which need to be controlled by long-term medication if they still exist after adjustment of diet and lifestyle habits, and as long as blood pressure and blood sugar are controlled within reasonable limits, the incidence of related complications and target organ damage will be significantly reduced.
