COPD is a long-term, progressive disease; four separate stages have been identified. The more you know about how the disease progresses from stage to stage, the better you’ll be able to manage it. The stages range from mild to very severe, and each has its own symptoms (see below).

Keeping your healthcare provider up to date.

By working closely with your healthcare provider, adjustments can be made to your treatment and lifestyle to better manage your symptoms as they change. The ultimate goal is to maintain and improve your quality of life.
