Exercise induced asthma refers to the pathological phenomenon of airway hyperresponsiveness, which leads to acute airway stenosis and increased airway resistance after strenuous exercise. For symptoms such as cough, chest tightness, shortness of breath and wheezing that occur within five to fifteen minutes after exercise, accompanied by the decline of relevant parameters of lung function, they can be relieved within thirty to six minutes. Sports asthma also occurs at any age, more men than women. Sports asthma is also known as exercise induced asthma, which is a special type of bronchial asthma. Exercise can be a single trigger, as one of multiple triggers, and exists in specific asthma patients. Clinical manifestations include chest tightness, wheezing, shortness of breath, cough, dyspnea, mental tension, stomach discomfort, sore throat and other symptoms. Some patients also have no typical asthma symptoms, such as headache, abdominal pain, muscle spasm, fatigue and abnormal feeling during exercise. When treating exercise-induced asthma, the duration of drug treatment should be at least half a year to better control the symptoms of asthma, otherwise it is easy to lead to the onset of asthma, but drug treatment often has many side effects.
