Hi 'three' and thanks for your post.
You may be aware that COPD affects all patients differently. Having said that, it stands to reason that, based on all we know, there are treatments for COPD (inclusive of life-style changes), that can actually slow the progression of the disease.
The answer to your question is, COPD is not a death sentence and, there certainly is hope for folks diagnosed with this disease.
I thought you might find it beneficial to look over this material which focuses on COPD and hope: https://copd.net/spotlight/maintaining-hope-awareness.
What do you think?
