Asthma is one of the most common chronic diseases, currently affecting 300 million people worldwide, and its prevalence has continued to rise in recent years, especially among children. Although asthma cannot be cured in the short term, it can be effectively controlled. Most people with asthma can get good control as long as they adhere to standardized treatment. When asthma is controlled, patients can: 1. have no symptoms that bother them day and night 2. use little or no emergency medication 3. fully enjoy a normal life 4. have normal or near-normal lung function 5. avoid severe asthma attacks The main symptoms of asthma are recurrent episodes of wheezing, coughing, chest tightness and dyspnea, which are especially severe at night and in the early morning. Asthma is a chronic inflammatory disease of the airways, and this chronic inflammation can cause airway hyperresponsiveness; when the airways are exposed to various risk factors (or triggers), it leads to airway obstruction and airflow restriction, resulting in the various symptoms mentioned above. Common risk factors for asthma include exposure to various allergens (e.g., dust mites, animal fur, cockroaches, pollen, fungi), occupational irritants, tobacco smoke, respiratory viral infections, exercise, strong mood changes, chemical irritants, and medications (e.g., aspirin and beta-blockers). Acute attacks (or exacerbations) of asthma are intermittent, but the inflammation of the airways is chronic and persistent; therefore, the treatment of asthma requires long-term standardized therapy, and the current medications for asthma are divided into two categories: long-term control medications and symptom-relieving medications (emergency medications). For most asthma patients, long-term control medications need to be used daily to reduce various symptoms, improve lung function, and make them less likely to have attacks or no attacks. Symptom relievers (emergency medications) are used temporarily to relieve symptoms such as coughing, wheezing and chest tightness that occur during acute attacks. To achieve and maintain asthma control, a partnership is needed between the person with asthma and his or her health care provider. Many Olympic athletes, famous leaders, celebrities, and ordinary people with asthma can live well.
