G'morning Sue99sstuff and thanks for your inquiry. I see that Lynn has provided you with an excellent answer as well as a link to an article on the staging of COPD. I thought you also might find it helpful to look over this article on the progression of the condition: https://copd.net/uncategorized/expert-answers-progression/.

Hi Sue99sstuff - The progression of COPD varies from person to person. If COPD is detected early and treatment is started, it can do a lot to slow the progression. Overall health obviously can play a part in any chronic condition and COPD is no different. However, as you know, there are stages to COPD that can be identified. Here's an article that describes the stages and some of the symptoms associated with each stage.
