Thanks. I was just diagnosed with stage 1, very mild COPD. I was looking for info about how long I might be able to stay at that stage. I have no symptoms, hike 9-15 miles weekly, attend Zumba classes and dance class. I am 60, not overweight, stopped smoking 3 years ago, and have good cholesterol and blood pressure. It sounds to me like no one can really give me an answer to this, but that it might be possible to stay stage 1 for a long time.
