Bronchial asthma is a chronic airway inflammatory disease, the main manifestations are recurrent cough, wheezing, shortness of breath and chest tightness. The main purpose of bronchial asthma treatment is to control symptoms, reduce the acute attack of asthma and improve the quality of life of patients. Asthma patients should pay attention to the control of asthma from the following two aspects. Allergy is an important cause of asthma. Different patients may have different allergens, and there may be one or more allergens. Common inhaled allergens can be dust mites, molds, pet dander, pollen, weeds and so on. There are different protection methods for different allergens. For specific methods, you can ask doctors, nurses or pharmacists who carry out asthma health education. Upper respiratory tract infection is another important factor to induce asthma exacerbation or acute attack. Therefore, it is very important for asthma patients to reduce respiratory tract infection. Therefore, we need to pay attention to: going to crowded places less, paying attention to room ventilation, avoiding contact with patients with respiratory diseases, paying attention to a balanced and healthy diet, and exercising properly to improve physical resistance. Drug therapy is the most important means to control asthma. Asthma treatment drugs include control drugs and remission drugs. Controlled medication includes leukotriene regulator (montelukast sodium, etc.), inhaled hormone, etc. It must be noted that controlled medication must be used regularly according to the requirements of doctor&;s advice, and regular follow-up visits should be made. It is forbidden to reduce or stop medication on its own when symptoms improve. If you are in doubt about medication, you can consult professional doctors and pharmacists to prevent the insistence on medication from being affected by your lack of understanding of medication.
