Emphysema, quit smoking, you're fine.

Emphysema is mainly caused by excessive expansion of the lungs and decreased elasticity, resulting in progressive dyspnea, and lung function is also declining year by year. Of course, smoking cessation is the most effective measure to slow down lung function damage. However, during the remission period, it is also recommended that patients regularly take β2 receptor agonists and long-acting anticholinergic drugs for a long time, because these drugs can prevent the number and frequency of attacks and reduce the number of hospitalizations.
