Asthma is actually bronchial asthma, a chronic airway inflammation, with episodes of dyspnea and wheezing as typical symptoms, and atypical symptoms including chest tightness, coughing and coughing. The onset of the disease can occur from childhood to old age, and the peak of the disease can be clinically divided into childhood and old age, which can be improved by itself or through treatment. Bronchial asthma is a heterogeneous disease, which is an airway inflammation with eosinophil infiltration. Its chronic airway inflammation is different from the chronic airway inflammation of chronic obstructive pulmonary disease, which needs attention. Asthma attacks are associated with external irritants. The symptoms of asthma are episodic and the severity and duration of an attack vary greatly among individuals. In mild cases, patients have a feeling of chest tightness and shortness of breath that lasts for several minutes, while in severe cases, there is extreme dyspnea that lasts for several weeks, and sudden death can occur in severe asthma attacks. Asthma can be relieved in a relatively short period of time after treatment, and in some cases it can be relieved naturally and the symptoms will improve significantly, which can be easily ignored and can cause great harm. That is why it is important to pay attention to the disease of asthma, which also requires regular treatment.
