hello, I am a 47 year old male, who since the first of Janurary 2007 have lost, with all the thanks going to the Lord... now over 160+lbs. I am now able to walk up to a mile and I can do my own yard work, car care, grocery shopping, etc, etc,....

I was at the Dr.'s office today and he done a fasting blood test on me, all of my levels were great, Glucose 84, Triglycerites 92, Cholesterol 157, Potassium 4.0, LDL 110, HDL 29 a tad low, but my CO2 was slightly elevated it was 34.3, he also checked my 02 saturation and it was 96%, he does not seem concerned about this slight elevation of the C02, but I just was wondering, why it should be a little high, I am doing great as far as motivation, and the ability to get around now, I am short of breath at times, but nothing big at all... Also my blood pressure is great 118/78...

Can anyone give me so insight on this?

Thanks,
