Is asthma hereditary? Is asthma hereditary?

Asthma, also known as bronchial asthma, is a chronic airway inflammation that is very harmful and difficult to treat. Asthma has not been cured for a long time, which makes many patients worry that the disease will be passed on to their next generation. Especially when preparing for pregnancy, the existence of asthma makes many families quite concerned. So, is asthma hereditary? Let’s take a closer look at this disease.

1. Is asthma hereditary?

Regarding the question of whether asthma can be transmitted to the next generation, according to experts' clinical experience, allergic asthma is a common type of asthma, and it is a disease with a certain genetic tendency. Someone once surveyed 1,500 patients with allergic asthma and found that 48.4% of their family members had a history of allergies; while among 876 normal people, only 14.5% of their family members had a history of allergies. This shows that children of people with a history of allergies are more likely to suffer from allergic asthma than the general population.

2. Is asthma likely to be inherited?

According to foreign reports, the rate of endogenous asthma in a family with endogenous asthma is significantly higher than that in a family with exogenous asthma, and vice versa. This shows that different genetic genes make some people susceptible to exogenous asthma and others susceptible to endogenous asthma. In short, it has been confirmed that asthma is related to genetics. From the perspective of exogenous asthma, it seems to be more closely related to family atopic tendency. Therefore, some people believe that asthma is a multifactorial genetic disease with a heritability of about 70% to 80%.

Since there are many types of asthma, each disease is different, the probability of inheriting asthma is also different, and allergic constitution has a significant genetic tendency. There are many reasons for asthma, but one thing is certain: asthma is related to genetics. A set of statistics proves that if both parents have asthma, the asthma incidence rate of their children can exceed 50%; if one of the parents has asthma, the incidence rate of their children can drop to 20%; if neither parent has suffered from asthma, the chance of their children suffering from asthma is only about 6%.
