So far, asthma cannot be cured, but it can be cured and prevented, and the number of recurrences can be reduced. Kechuanling Capsule has this medicine, but it is not a panacea. Haha, asthma is caused by many kinds of diseases. Chronic airway inflammation involving cells, especially mast cells, eosinophils and T lymphocytes; in susceptible individuals, this inflammation can cause recurring symptoms of wheezing, shortness of breath, chest tightness and/or coughing, mostly at night Or occur in the early morning; such symptoms are often accompanied by widespread and variable expiratory flow velocity limitation, but can be partially relieved naturally or with treatment; such symptoms are also accompanied by increased airway responsiveness to a variety of irritating factors. Opinion Recommendation: Although the cause and pathogenesis of asthma have not been fully elucidated, the current treatment methods, as long as they can be treated in a standardized and long-term manner, can achieve ideal control of asthma symptoms for the vast majority of patients, reduce recurrence or even eliminate attacks, which is the same as that of normal people. Live, work and study the same. Although asthma cannot be cured, asthma can be cured by implementing the "three steps" of disease assessment, disease treatment and disease monitoring for the purpose of control, especially the use of combined treatment programs confirmed by global evidence-based medicine. Controlled. Life care: There are many reasons for bronchial asthma attacks. Some reasons are obvious, but some reasons are often hidden. Doctors and patients need to work together to find out. In particular, the patient and his family members should be in close contact with each attack. Please discuss the situation with your doctor in detail to facilitate diagnosis and treatment.

(2) Non-specific physical and chemical factors, such as inhalation of smoke, dust and vegetable oils , gasoline or paint and other odors, as well as cold air, can stimulate the sensory nerve endings under the bronchial mucosa, reflexively cause vagus nerve excitement and cough, and cause bronchial smooth muscle spasm on the basis of airway hyperresponsiveness. (3) Microbial infections: colds and Upper respiratory tract infection is the most common cause, which is more obvious in winter and spring or when the climate changes. Respiratory tract infection, especially viral infection, is more likely to cause asthma attacks in children. (4) Overwork: sudden intense or long-term physical labor, Intense competitive sports can induce asthma. (5) Mental factors: Mood swings can be triggers.
