Asthma is a chronic respiratory disease characterized by chronic airway inflammation and airway hyperresponsiveness. It manifests as expiratory dyspnea and chest tightness.
Asthma is a complex, heterogeneous disease with a genetic predisposition, and can be caused by allergenic factors such as pollen, dust mites, and paint, as well as non-allergenic factors such as smoking, excessive exercise, and obesity. Typical symptoms are paroxysmal, croupy dyspnea, which may be accompanied by shortness of breath and chest tightness.
In the clinic, ventilation function test, bronchial diastolic test, chest CT and other tests can be done, so as to understand the severity of asthma and develop a personalized treatment plan.
Asthma patients are advised to seek timely medical treatment.
