My excercise of choice is cycling, I had made some changes in my lifestyle in my early thirties because my Grandfather was diagnosed with type 2 D when he turned 70 and my mom was diagnosed at the age of 60.
I expected at that rate I would be diabetic at the age of 50. So it certainly was unexpected when I had the symptoms of diabetes at the age of 42 after I had modified my diet and began exercising regularly. I had been mountain biking for recreation for 5 years and racing competitively for 3 and a half years, with a couple of podium finish's.
I was not a lot over weight 5' 9" and around 180, (very strong due to the Mountain biking) not fat by any means just thick. I was excercising consistantly and eating fairly well.
I was having more and more fatigue, and went to my primary who sent me to a sleep study, where I was diagosed with moderate sleep apnea. This of course made me think all the symptoms, unusual thirst, unexpected weight loss, blurry vision, and hard core fatigue, were related to the apnea.
I am now doing both MTB riding and road cycling trying to do 125+ miles a week.
Most rides last between an hour and an hour and a half, consisting of between 30 and 45 miles on the road bike or 12-15 on the mountain bike trails.
I have recently purchased a heart rate monitor and usually am hovering around 150 bpm while riding.
We will be riding a 66 mile ride this Friday and look forward to a 100 mile ride next Saturday.
When I get three or four days of 90 plus minute rides a week my blood sugar numbers are spot on perfect for a couple of days subsequent. You can't panic about high BS numbers right after excercise because it is likely just your liver releasing glucose to provide energy.
