If you do, have you had to reduce your insulin intake since having COPD? I am having problems lately with my glucose levels dropping steadily and having 'hypos' even though my eating habits haven't changed. The only reason I can think of is that I am using up more calories through needing more energy to breathe ~ I'm breathless often! I'm on Spiriva and Ventolin inhalers. Am due to see Diabetic Nurse soon but just wondered if anyone else has experienced this? Thanks.
