Hi . Welcome to the community! That's a difficult question because the COPD journey can be different for everyone, but here is an article that might answer some of your questions: https://copd.net/living/understanding-end-stage. Keep in mind that not everyone will progress to end-stage and that many people who do reach end-stage are able to live full lives for a long time after. We have members of this community who were diagnosed as end-stage more than two decades ago. Have you been diagnosed long? Wishing you the best. - Lori (Team Member)
