which or both?

Is COPD and emphysema the same thing?  If not then what makes them different?  Which is worse?

COPD is an umbrella term. It covers emphysema and chronic bronchitis. Until recently  Asthema was covered under it. I do not know why it was taken out, but it was. I don't think the medical profession views it as progressive, but it very well  can be. They are both just as bad, just in different ways. Both are progressive. If caught early and with the right group of meds, and rehab and exercise you will soon learn it is not a death sentence. Stop smoking and eat well and enjoy life. That is the best I can tell you. That is what I did. I just have a new norm. It was hard to accept but I did. Now I just want to have fun.
