Im a 49 year old male.. Ex smoker.. And I've been diagnosed with COPD... But I have been told that there's nothing I can do to try and help or improve my lung capacity. I'm from Port Elizabeth, a small town in South Africa... Both doctors have instructed me to stop smoking (which i have for the past 3 months).. But told me that there's nothing I can do to improve my lungs. I've had a lung function test, and the results were extremely poor. Based on my height, weight, and age...I was supposed to be at 650..but I'm at 150. Ive become very depressed and need some advice/ knowledge regarding my condition
