Swimming chest tightness does not exclude physiological factors or pathological factors caused by chronic bronchitis, chronic obstructive pulmonary emphysema and other causes.
1. Physiological factors: after overexertion, physical exertion is more, which increases the heart’s oxygen consumption, affecting the normal operation of the lung function, the symptoms of chest tightness after exertion.
2. Pathologic factors:
(1) chronic bronchitis: patients may suffer from chronic bronchitis, patients after exertion, the respiratory tract does not have perfect defense function, thus for the inhaled air can not be filtered in a timely manner, the cilia on the mucous membrane of the airway can not remove the airway foreign body and bacteria, blocking the bronchial tubes, and then there is dyspnea, which is manifested in the symptoms of chest tightness after exertion.
(2) chronic obstructive pulmonary emphysema: the patient’s respiratory fine bronchial end tissue due to the airway volume increases, resulting in fine bronchial dilation, and then alveolar septum to a certain degree of destruction, the elasticity of the lung tissue changes, the lungs appear pathological disorders, resulting in the patient’s dyspnea after exertion, which leads to chest tightness after exertion.
Swimming chest tightness should promptly go to the hospital for consultation, cooperate with the doctor for treatment, alleviate the symptoms, and recover as soon as possible.
