Recently, I've been experiencing chest pain and tightness in my chest. The hospital examination indicated a respiratory disease, but the medication hasn't been very effective. Recently, my cough has worsened. What is the true meaning of emphysema?Doctor's answer:
Emphysema is primarily caused by a history of chronic bronchitis and is closely related to long-term smoking, infections, industrial pollution, etc., which lead to bronchial or obstruction. The main symptoms include recurrent cough, sputum production, chest tightness, shortness of breath, and wheezing. The chest appears barrel-shaped externally, and rales can be heard during percussion.
