Internal cause refers to a specific constitution, which is mainly determined by genetic factors. Because asthma is mostly related to allergies, if parents have a history of asthma or allergic diseases, this allergic constitution will be passed on to their children, and children with allergic constitution are relatively more prone to asthma.

The external factors are mainly environmental factors, including various allergens, irritating gases, virus infection and mycoplasma pneumoniae infection, living area, room conditions and climate, drugs, exercise, food and food additives, eating habits, social factors and economic conditions.

If people with allergies are often exposed to these possible causes, they may suffer from asthma.

2.IgE is an allergic indicator. If IgE rises, it indicates an allergic state.

It is suggested to download medical respiratory software to standardize the treatment and management of asthma.
