People who have a disease want to “get to the root of it”, but in reality, many diseases cannot be completely cured. However, with good management, most diseases can be managed well, and asthma is one of them. Asthma is a chronic inflammatory disease of the airways, and this inflammation is long-lasting and requires long-term management. How to improve the quality of life and minimize the number of attacks is the concern of every asthma patient. Content of asthma prevention and management 1. Recognizing asthma Different stages of development have led to different perceptions of asthma. The latest concept emphasizes that asthma is a chronic non-specific inflammatory disease of the airways. During the development of asthma, a large number of different kinds of inflammatory cells, inflammatory mediators and cytokines are involved; airway hyperresponsiveness is the main feature of asthma; typical manifestations are episodic wheezing, cough, sputum and audible expiratory phase croup in the lungs. Not all asthma is characterized by wheezing, as in early allergic asthma where cough is the only symptom; asthma is not always triggered by allergies, some are triggered by upper respiratory tract infections, strenuous exercise, medications, etc. Many patients do not have this knowledge and do not have the knowledge. Many patients fail to get timely diagnosis and treatment due to lack of knowledge, which delays the condition. 2.Avoid contact with allergens and chemical irritants The common triggering factors of asthma are upper respiratory tract viral infections, allergens such as dust mites, animal fur, cockroaches, pollen, mold, tobacco smoke, air pollution, strenuous exercise, emotional changes and contact with chemical irritants, drugs, etc. Patients who are only allergic to certain specific allergens that cause asthma must be observed carefully and be aware of them, and avoid contact with allergens as much as possible to prevent asthma attacks. However, most patients are sensitive and react to a variety of allergens. Although desensitization therapy has the effect of reducing the symptoms of allergic asthma or reducing the frequency of asthma attacks, the clinical effect is not satisfactory at present due to the limited types of allergen reagents, cumbersome treatment methods and poor specificity. 3, monitoring of the disease Asthma patients probably will not forget that doctors always recommend pulmonary function tests. Pulmonary function, like liver and kidney function during a physical examination, needs to be monitored. Pulmonary function tests can help diagnose diseases such as asthma, chronic obstructive pulmonary disease, interstitial lung fibrosis and other related diseases, as well as observe changes in the condition and determine the effectiveness of treatment and prognosis. The difference is that pulmonary function tests do not involve blood sampling, but simply “blowing”. Of course, blowing is not as simple as normal breathing, but must be done in a rhythmic and vigorous manner according to the doctor’s requirements, otherwise it will affect the doctor’s judgment and treatment. The main indicators of lung function testing are “one second volume (FEV1)”, “one second rate (FEV1%)” and “peak airway flow rate (PEF)”. In general, these indicators gradually decrease in patients with long-term, recurrent asthma attacks. Therefore, the purpose of pulmonary function tests is to monitor whether the asthma is acute, how well it is controlled, and how severe it is. Patients with asthma should be aware of the effects, dosage, usage and side effects of common medications. Some patients and their families often ask, “When can I reduce my medication or stop it completely?” Some patients often fail to grasp the timing of drug reduction and discontinuation, resulting in recurrence of the disease that has been easily controlled. Many patients are afraid of inhaled corticosteroids in particular. In fact, inhaled hormones are the safest and most effective asthma treatment method at present due to high local drug concentration, strong effects, low side effects and small doses, while oral hormones are generally not preferred. Of course, not all asthma patients must use hormones, and the specific treatment plan will be formulated by the doctor according to the severity of the disease. In addition, many patients think of using antibiotics when they have asthma, but it has been found that the cause of acute asthma attacks is mostly related to viral infections, and antibiotics are not effective against viruses. In conclusion, the treatment of asthma is not an overnight matter, asthma should be faced with a peaceful attitude to minimize asthma symptoms and improve its quality of life.
