Walking asthma can be caused by respiratory problems, such as poor lung function, or when the heart is not well, such as myocarditis or a poor heart function, will walk asthma. There are also other chronic diseases, there are a lot of consumptive diseases lead to the body’s physical strength is insufficient, can also cause walking gasping for air, there is a lack of exercise, usually always stay still, suddenly walk very fast will certainly be gasping for air. Focus on the lung function is not good when walking wheezing, there are the following situations: 1, hypoxia, if a person has hypoxic lung disease, any activity may let him gasp up, not to mention walking. 2, in addition to hypoxia there is also a ventilation is not good, ventilation is not good, for example, slow obstructive pulmonary disease, old chronic bronchitis, emphysema patients, in the speed of breathing faster, originally because of resistance to the time of exhalation is relatively large, and now the patient has to walk very fast to walk, the lung function is not good. When the resistance is relatively large, now an activity due to the use of oxygen, so most people will accelerate breathing, but this time because of its own exhalation of obstacles, so it will form a gasping state, which is the cause of walking wheezing.
