Hi CM1092, and thanks for your post and your question. I am hopeful others in the community will chime in and share their own personal experiences when it comes to COPD, bloating and weight gain/loss.
We do have a number of articles, published right here on COPD.net, which focus on those very topics. For your convenience, here are some links to several of the articles.
First, this link to material about bloating and COPD: https://copd.net/search?s=bloating.
And next, these articles on weight and COPD: https://copd.net/search?s=weight%20gain%20loss.
I do hope you find this information is helpful in a practical way.
I will wish you 'good luck!' seeing your doctor at the end of the month.
If you don't mind, kindly check back and let us know how this all turns out for you.
All the best,
Leon (site moderator COPD.net)
