I am 45 yo white male, I weigh aprox. 380 lbs, I have sleep apnea, and have very recently began cpap treatment. My chloresteral is good (157), triglisorides are ok, and blood pressure is in check. My question is I get winded very quickly, when I climb in and out of my tractor (I drive a semi truck for a living) I get really out of breath, and sometimes my upper chest slightly burns. It always goes away very shortly usually 20-30 seconds. My body feels constantly fatigued. I also have chronic broncitus. Aside from losing weight what else can I do .
