My mother was recently diagnosed with COPD, she has also had tuberculosis in the past, and has already had some of her right lung cut away, so her lungs are already very weak. She has smoked heavily for many years and is continuing to do so, she's had lots and lots of chest infections in the past. The question I really wanted to ask is, how long do you live with this disease? She is not stopping smoking, she has made that very clear to me, and she doesn't exercise very much either. I'm very worried about her.
