Hi BestiCanDo and thanks for your post/inquiry. As you can see, one of our members have already chimed in in response to your question. (thanks, nena56!)
You may be aware that frequently, other medical conditions can accompany COPD. The term for that is 'comorbidities'. Since you described symptoms associated with your condition, and indicated this is a concern of yours, I would suggest you speak with your physician about this. The doctor may be able to help you to manage this. What do you think? Leon (site moderator)
