Having a FEV1 of 27%, twice a year I go for free checkups at a local public hospital here in Spain and see a different lung doctor every time, they all agree I have severe COPD but while most of them say I have chronic bronchitis, the one I saw a couple weeks ago said no, no, I had emphysema instead. I don't know why I'd like to know, even though both diseases are incurable and progressive, I'd like to know which one I'm probably going to die from. Now my question is: Is there a way to determine which of the two I have? Is there anything I could tell the doctor during my next checkup in April to have him/her formulate a more accurate diagnosis? Thanks for any suggestion. Good luck to all fellow sufferers - forum readers!
