Running asthma is serious, mostly not caused by disease, but by lack of exercise, poor physical endurance and low vital capacity; A few people may be caused by respiratory diseases, such as asthma, tracheitis and pulmonary insufficiency. In daily life, such people often have respiratory symptoms, such as cough, expectoration, shortness of breath, asthma and so on. It may also be caused by environmental factors, such as cloudy or foggy days. When the weather pressure is relatively low, there will be hypoxia when you exercise vigorously outdoors.

When severe asthma symptoms occur during running, the main consideration is airway inflammation, and the most common is airway hyperresponsiveness, such as allergic asthma and asthmatic bronchitis caused by allergies. Due to the stimulation of airway mucosa, contraction and spasm of airway mucosa smooth muscle, exudation of a large number of inflammatory secretions, and even phlegm embolism blocking the airway, the airway is blocked to varying degrees, which reduces the ventilation and ventilation function of the respiratory system and even causes respiratory failure, so severe asthma symptoms occur during running. At this time, we should check the lung function, take CT scans of both lungs, check allergens when necessary, make clear the cause, and carry out symptomatic treatment and etiological treatment in time.
