I am a 68 year old male and was diagnosed with COPD a number of years ago. I have always been VERY overweight. The last couple of years I have been dieting and have lost almost seven stone and still have some to lose. My breathing has improved greatly and I can do things I had not done for years. The shortest walk would see me stopping several times for breath. Now I can manage it with out stopping at all. Also my Blue inhalors I was getting two a month and running out long before I was due for another one. Now I have only one a month and that is more than enough to see me through, in fact I now have some spares.
