Do i have copd? i was born with a slightly narrow windpipe and have been having regular but increasing breathing difficulty and wheezing.

See a doc.: Too young to have copd, unless you have asthma and chronic ling pathology. Narrow airways, one tends to out grow. First one has to determine if you are wheezing. And then treat you accordingly. Hopefully you are a non smoker and do not have major respiratory allergies.

Not really: In the real sense of the phrase, any chronic obstruction to include asthma, emphysema, chronic bronchitis, and things called bronchiolitis which may be the one you have is COPD but in the loose sense, COPD is emphysema, which is a destruction of lung tissues or loss of some connective tissue and bowing of the midsize airways that lead to enlarged air sacs and loss of surface area.
