Exercising before a fasting blood test?
Hi,
I just recently had a fasting blood test. That morning, about 3 hours before the test, I engaged in a 25 minute jog ( 5.5mph, as I do nearly every morning). Unfortunately, no one had informed me that I should abstain from exercise prior to bloodwork like this. So I'm wondering, how would exercise affect my results?
Of particular (though not exclusive) interest are the following:
-> Triglycerides (Total was 39. Normally it's around 50 for me, so this is an obvious improvement.)
-> Glucose (Total was 88. Last test done was 2 years ago, and was 79)
-----> Regarding the glucose: would the amounts be higher (due to the liver releasing sugars into the blood) or lower (due to the body's insulin response)?
I'm 32, 6'0, 220lbs. I have also started juicing a lot lately (over the past month), mostly vegetable juices flavored with apples and a lemon.
My biggest concern is insulin sensitivity: 2 years (and about 15lbs) ago I was diagnosed with flatline hypoglycemia (Results: Fasting: 79; 1hr: 81; 2hr: 71). I've since been working towards improving my insulin sensitivity.
Can I generally trust the result that I received (ie, it's under 99, so I'm OK), or was this blood test way skewed due to the exercise? Should I re-test?
