There is no such thing as asthma being serious for a few years. Most patients with asthma can effectively control their asthma attacks with standardized management and generally do not continue to have exacerbations.
Asthma is a heterogeneous disease characterized by chronic airway inflammation. Some patients can find allergens or other nonspecific irritants that cause asthma attacks, and weaning the patient off and avoiding exposure to these risk factors for a long period of time is the most effective way to combat asthma.
Others need to be guided by their doctors to standardize the use of controlling and relieving medications to control symptoms and prevent future risks over the long term, and ultimately to achieve the goal of enabling patients to live, learn and work as normal people do, on the basis of treatment with the smallest effective dose of medication or without medication.
Once diagnosed with asthma, should promptly go to a regular hospital, with the doctor to improve the relevant examination, and standardized treatment.
