Symptoms of breathlessness after coughing are mostly seen in bronchitis, emphysema, bronchial asthma, pneumothorax, etc., which should be treated reasonably according to the cause. 1. Bronchitis: patients with bronchitis caused by bacterial infection may have symptoms of coughing and shortness of breath, and if bronchial spasm is caused, the phenomenon of breathlessness after coughing may occur. 2. Emphysema: patients with emphysema caused by long-term smoking, dust inhalation and infections may have coughing symptoms, and in severe cases, lung function may decline, resulting in chronic obstructive pulmonary disease, usually with chest tightness, shortness of breath, wheezing and other symptoms, so coughing may be breathless. 3. Bronchial asthma: patients with bronchial asthma in contact with allergens or acute infections, there may be coughing, wheezing symptoms, airway spasm will lead to breathlessness. 4. Pneumothorax: In patients with pneumothorax, gas enters the pleural cavity and stimulates the cough receptor, resulting in coughing. Because pneumothorax also usually leads to chest tightness, dyspnea, so there will be a cough after the phenomenon of dyspnea. After coughing breathlessness, you should go to the hospital in time to determine the cause of the disease and then do targeted treatment.
