What causes asthma

summary

When it comes to the risk factors of asthma, we should all know that allergens are very common in infants. However, with the increase of age, we can avoid allergens. In addition to allergens, which factors will lead to asthma?

What causes asthma

First, the patients were caused by inhaling specific or non-specific substances. The specific substances were mainly fungi, pollen, dust mites and animal dander, while the non-specific substances were mainly sulfur dioxide, ammonia chloride and sulfuric acid; If the patient is occupational asthma, the main specific substances are phthalic anhydride, protease, toluene diisocyanate, ethylenediamine, amylase, penicillin, animal dander, excreta and silk, and the main non-specific substances are formic acid and formaldehyde.

Second: the patient is caused by repeated episodes of respiratory tract infection. In patients with asthma, there may be specific IgE of mycoplasma, virus and bacteria. If patients inhale the corresponding antigen, it will lead to the occurrence of asthma. When patients are infected with the virus, it will cause direct damage to the respiratory tract epithelium of patients, thus increasing the response of patients with respiratory tract. Some scholars believe that after patients are infected with the virus, it will increase the histamine released by basophils. In addition, in some rural areas, some parasites, such as hookworm and Ascaris lumbricoides, can also cause asthma.

Third: patients due to the consumption of allergic food, this situation is more common in infancy, but with the growth of their age, the incidence of asthma caused by patients gradually decreased. Under normal circumstances, the food causing allergy mainly includes milk, fish, eggs, shrimp and crab, etc.

matters needing attention

The above is the main cause of asthma, we only master the pathogenic factors of asthma, so as to effectively prevent the attack of asthma, as long as asthma patients can effectively control the number of attacks, so that the disease will slowly improve, a long time, disease recovery is not impossible. ??
