Asthma is not an infectious disease and cannot be transmitted. But children with genetic predispositions, such as parents with allergies and asthma, are slightly more likely to develop asthma.
The formation and onset of asthma is not only related to genetic factors,哮喘治療 but also affected by environmental factors. A number of survey data show that the incidence rate of relatives of asthma patients is higher than that of the population, and the closer the relatives are, the higher the incidence; the more patients in a family, the higher the incidence of relatives; the more severe the patient's condition, the higher the incidence of relatives . Analysis of environmental risk factors affects asthma. The main content includes students’ exposure to inhalable animal and plant allergens (allergens), air pollution, respiratory infections, especially for virus and mycoplasma infections, exercise and hyperventilation, changes in weather, certain foods and Food additives, drugs, and neuroscience research on spiritual and cultural factors include social emotional agitation, fear, etc. Based on genetic factors, any of the above environmental factors can induce asthma. Of all the environmental factors that cause asthma, allergies are the most common and most important. One of the more common indoor allergens is house dust mites, cockroaches and other resource insects, molds, etc.; outdoor allergens often help pollen, ragweed, and mold. Some foods such as milk, eggs, fish, shrimp, crab and other protein components can also be used as allergens to induce asthma.
The causes of asthma are complex, but mainly include two aspects, namely,肺炎病徵 physical and environmental factors of asthma patients. The patient's physique includes subjective conditions such as genetic quality, immune status, mental and psychological status, endocrine and health status, which are the key to the cause of the patient's susceptibility to asthma. About 40% of patients have a family history.Environmental factors include various allergens, irritating gases, viral infections, living areas, room conditions, occupational factors, climate, drugs, exercise (hyperventilation), food and food additives, eating habits, social factors and even economic conditions, etc. Both may be more important reasons leading to the development of asthma. Allergens are an important cause of asthma and are mainly divided into inhaled allergens (indoor allergens and outdoor allergens) and food allergens. Indoor allergens include house dust, dust mites, fungi and cockroaches, while outdoor allergens include pollen and fungi.
The pathogenic factors of asthma are divided into two categories: pathogenic factors and predisposing factors. pathogenic factors refer to the factors that cause the first attack and are also the main reason. They play an important role in the occurrence and development of asthma. precipitating factors refer to factors that can induce latent asthma reactivation or acute asthma attacks in asthma patients. Among the above two types of factors, some factors, such as allergens, irritating and harmful gases, occupational factors, viruses, food and drugs, have a dual role, not only causing asthma, but also playing an important role in the development of asthma.
