At present, asthma cannot be cured, and can only be prevented by controlling symptoms with medication and avoiding exposure to allergens. 1. Asthma is a respiratory disease mainly characterized by chronic inflammation of the airways, which can be triggered by exposure to allergens or other factors. 2. At present, the cause of asthma is still unknown, and most of them are believed to be related to genetic or environmental factors. There is no cure for asthma, and it can only be controlled by reducing bronchial inflammation through medications such as (salbutamol, terbutaline, montelukast, budesonide, etc.), and reducing attacks by avoiding exposure to allergens. When an acute asthma attack is a respiratory emergency, it is necessary to go to the hospital immediately for further treatment, and the treatment plan should be formulated and adjusted according to the individual’s symptoms and signs under the guidance of the clinician at any time.
