Generally speaking, asthma results from allergic reactions to external allergens, such as dust mites, plant pollen, molds, and even certain foods. Patients with dust mite allergy tend to have attacks all year round, while patients with pollen allergy generally have symptoms in the early spring and fall, and later in the year. Asthma cannot be cured at present because the onset of asthma is related to allergic constitution, which cannot be changed. The main goal of asthma treatment is to inhale medication regularly to minimize acute attacks and maintain a normal quality of life. The first step to successful asthma treatment is to establish the correct concept of treatment, not to pursue the so-called “cure”, which is easily deceived by quacks. Long-term treatment means insisting on medication even in the season of non-onset, and not waiting for the symptoms to become obvious before using medication. Commonly used drugs are inhaled hormones combined with long-acting bronchodilators. Many patients are concerned about the side effects of long-term use of hormones. In fact, inhaled hormones are different from oral hormones because the dose really absorbed into the blood is extremely small, and the side effects of long-term use are rare. If the medication is only used during acute attacks, not only will it affect normal life, but the asthma condition will also get worse.
