The One Test Your Doctor Isn’t Doing That Could Save Your Life

Insulin resistance doesn’t happen overnight. When most of your diet includes empty calories and an abundance of quickly absorbed sugars, liquid calories, and carbohydrates like bread, pasta, rice, and potatoes, your cells slowly become resistant to the effects of insulin. Your body increasingly demands more insulin to do the same job of keeping your blood sugar even. Eventually your cells become resistant to insulin’s call, resulting in insulin resistance. The higher your insulin levels are, the worse your insulin resistance. Your body starts to age and deteriorate. In fact, insulin resistance is the single most important phenomenon that leads to rapid, premature aging and all its resultant diseases, including heart disease, stroke, dementia, and cancer. Insulin resistance and the resulting metabolic syndrome often comes accompanied by increasing central obesity, fatigue after meals, sugar cravings, high triglycerides, low HDL, high blood pressure, problems with blood clotting, as well as increased inflammation. Even without these warning signs, one test can determine high insulin levels years or even decades before diabetes develops. Early detection can help you reverse these Continue reading >>

    Fasting Insulin Level after 12-20 Hour Fast

    Had a fasting insulin blood test done at lab yesterday morning at 8:30 AM. It's the first time I've done it. Was curious. Only cost me like $26 to find out. I already knew I was highly insulin resistant type 2. i.e. I know that 1 unit of regular insulin only covers 2 mg/dL of blood glucose (as a corrective dose).
    I hadn't eaten any solid food before blood test, except for 20 hours earlier. I had coffee about 12 1/2 hours before test.. Nothing after the coffee.
    My Fasting Insulin was 12.9 uIU/ml and my fasting blood glucose was 124 mg/dL. (Normal fasting insulin range is 2.6 to 24.9 according to the blood test sheet).
    My calculated HOMA-IR score is then (12.9*124)/405 = 3.95. A score of 1.0 or less is normal from what I've read -- i.e. not insulin resistant.
    Anyways, since this is the first time I've done this test, I'd appreciate if anyone could chime in and tell me all they can about what I just found out with the test.
    Is there any way to determine how strong my pancreas is with this test? Or should I follow this fasting insulin test with another in a couple days where I drink like 100g of glucose 1 hour before the test? If the fasting insulin level is the same, then my pancreas is doing all it can do when fasting even right?

    I've never had any type of insulin test and it's never occurred to me to have one. My thought is with the way I eat my blood sugars are decent and that's all I care about.

Well I've done everything I can with respect to eating and can't get blood sugar below 110-135 range all day. So I am concerned about it. I am thinking my pancreas might be weakened too much.. but again you've seen the amount of insulin it's putting out. 12.9 .. normal is down to 2.9 .. so I guess it still must be somewhat strong? I'm just highly resistant.
