Asthma is an exacerbative disorder that cannot be cured but can be well controlled. If properly controlled, a 27-year-old asthma patient can achieve a normal life expectancy; if not taken seriously, sudden and severe attacks can be life-threatening. Asthma, as a chronic respiratory disease, is a reversible airway obstruction that can be controlled with medications. Most patients with well-controlled disease can achieve a normal survival if they are treated regularly. However, if patients do not undergo standardized and effective treatment and prevention, they may develop uncontrollable complications due to sudden attacks and asthma persistence. If rescued in time, the patient may survive; if not rescued in time, it may lead to sudden death. In conclusion, asthma patients should actively cooperate with their doctors, strengthen physical exercise in their daily life to enhance their physical fitness, and carry emergency medications with them in case of emergency.
