One of the causes of bronchial asthma is heredity. In fact, it should be said that it will inherit susceptible constitution, that is, allergic constitution. And this allergic constitution is not necessarily bronchial asthma, but easy to get allergic diseases, because it also depends on external factors. For example, after the great migration, the external environment has changed from temperate zone to tropical zone, and all the original external factors have disappeared, so it is not easy to get bronchial asthma.

Bronchial asthma

However, after the great migration, there will still be new allergens in the new environment, that is, promoting factors, and allergic skin diseases may be caused as a result. In fact, this is the same as people's physique, strong people, descendants of longevity families, will be healthy, strong, longevity offspring. Having a susceptible constitution also shows that the ability to resist this aspect is not strong. Therefore, the prevalence rate of the offspring of bronchial asthma family is higher than that of the general population.

Moreover, the closer the kinship is, the higher the risk of bronchial asthma is. If you do not take active defense and treatment measures, the more serious the disease will be, the higher the prevalence rate of their relatives will be. Some people directly say in the expression that asthma is related to polygenic inheritance. But asthma is different from other genetic diseases, because allergens and genetic susceptibility are comparable, in the absence of any intervention, susceptibility, incidence, the degree of disease will rise in the opposite direction.

Studies have also shown that patients who have suffered from exogenous asthma will have a multi-stage hereditary phenomenon, with a heritability as high as 56% to 76%. If juice endogenous asthma, the chromosome has recessive inheritance. And the smaller the incidence, the greater the heredity, while both parents have endogenous or exogenous asthma, and the prevalence rate of their children is as high as 75%. One of the parents is asthmatic, and the prevalence rate of their children is 50%.
