How bad does my bronchitis need to get before my doctors will consider a lung transplant?

Whoa, wait a minute. Lung transplantation is an avenue of last resort. There are specific indications before considering transplantation which carries with it a whole difference set of medical problems. Generally, the threshold is very high and it is only when life expectancy is very limited, when lung transplantation is considered.
Pretty Bad!! Don't be in a hurry for a lung transplant. It is a huge operation that is the last line of therapy for the most severe of lung problems - the last resort. Remember, every treatment has its downside, and a lung transplant brings its own special set of issues. Hang in there!
