What is asthma a disease? Asthma is a chronic, non-specific inflammatory disease of the respiratory tract. Chronic means that it is long-standing; inflammatory means that there is swelling and increased mucus in the airways due to inflammation, and the greater the degree of this inflammation in the airways, the more difficult it is to breathe air into and out of the lungs. The inflammation referred to here is a kind of “allergic inflammation”, which is the tissue damage caused by the immune response of the respiratory tract, not the usual infection-induced inflammation that requires antibiotic treatment, which requires hormonal anti-allergic inflammatory drugs. Is it necessary to use inhaled hormones for asthma treatment in children? Yes, except for some children with mild asthma who can be treated without hormones, most children with asthma need to use hormones for a long time to control their condition. This is because glucocorticoid inhalation therapy is the most effective long-term control of airway inflammation. Parents do not have to worry about hormones affecting their child’s growth and development. Compared to oral medications that act systemically, inhaled medications are administered using the inhaled airway route. Only about 10-20% of the inhaled medication reaches the lungs, some is exhaled, and most is deposited in the oropharynx, and the latter can be cleared by proper mouth rinsing, so the amount of medication that enters the body is very small. In addition, after the asthma condition is controlled, the amount of inhaled medicine will be gradually reduced, do not refuse treatment because of the fear of hormone side effects, asthma is not effectively controlled, it will aggravate the child’s condition and affect the child’s growth and development. The treatment of asthma in children needs to follow the principle of “long-term, persistent, standardized and individualized”. Among children with asthma, 80% of them can recover completely through treatment, while 20% of them will bring their asthma to the adult stage, so parents should not be discouraged and should actively cooperate with doctors. Many parents have many misconceptions about the treatment of asthma, for example, after regular treatment when their child has an asthma attack and the condition is under control, they no longer go to the hospital to receive follow-up examinations, and some parents also stop taking medication once the condition is under control, thinking that if the asthma does not attack, they can stop taking medication and reduce the amount of medication inhaled if they do not wheeze. Because asthma is a long-term process, parents must insist on caring for their children with asthma according to the standard treatment method, and they must follow the principle of “long-term, insistence, standardization and individualization”.
