<s>[INST] I am 43 years old male, diagnosed with early stages of empChatDoctora. I have stopped smoking since being told. What outlook does this have for me, I m petrified. My doctor told me not to stress that if I quit smoking immediately, that I won t even notice the difference. The results were shown on a ct scan, he believes that the small holes may repair themselves, is this possible? I didn t thing it was possible to be reversed. Can you please help me with some information? Thank you kindly. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Emphysema is structural lung disease. It causes structural changes in lung. These changes are not reversible. These changes are permanent. The important thing is not these structural changes, but functional defect if present due to these changes is more important. So better to get done PFT (Pulmonary Function Test). If this is normal than no need to worry about lung damage. But if PFT suggests obstructive defect than you need to take inhaled treatment. Chest physiotherapy and deep breathing exercises are also important. It is good that you have stopped smoking. So get done PFT and star chest physiotherapy. Hope I have solved your query. Wish you good health. Thanks. </s>
