I'm really concerned about COPD and was wondering if you could explain it to me. Is it something that can be managed with the right medication, or is it an irreversible condition? Also, are there any lifestyle changes I should consider to help manage COPD? I've heard there might be lab tests available to diagnose itcould you let me know if that's true? And, just curious, is there any connection between high blood pressure and COPD? Looking forward to your advice.
