Insulin Testing

insulin testing






It’s actually pretty easy to figure out how insulin causes insulin resistance, without really going into the matter in much depth at all.  The way hormones work, there is an optimal range for it, and anything under that will produce too little hormonal function, and anything over it will produce hormonal excess.

The idea of hormones needing to be balanced is a well known phenomenon actually, and when out of balance, we know that there are consequences to that, and while we can’t just assume there are with every hormone, we can measure people’s levels and pay attention to what happens when they are unbalanced one way or the other.

It’s pretty clear what happens when insulin levels get too low, this is what type 1 diabetes is actually, and people used to die from this pretty quickly.  Then insulin was discovered and there was a lot of excitement back then because people’s lives could now be saved.

There are also some type 2 diabetics who, after a long enough period of battling the disease, their beta cells can finally succumb to the disease and they can get to the state where they no longer can produce normal amounts of insulin, and may even not be able to produce much at all, like a type 1.

So it’s likely that in all the enthusiasm surrounding this wonder therapy, saving so many lives with it, and the fact that insulin will generally reduce the blood sugar levels of a type 2 as well, got people thinking, well why don’t we just give this to type 2’s as well?

We know that the type 1’s are low in insulin, as well as late stage type 2’s, but who cares about what their insulin levels are, if you have high blood sugar then this is for you.  Oops.

Generally, modern conventional medicine is pretty particular about who they want to give hormone replacement therapy to, and the first thing they require is that one get their levels tested, to see if the hormone is actually low enough to look to restore natural levels.

These people tend to want to test for everything actually, and if anything, they go way overboard, for instance they will test people for B12 levels prior to telling them to take an oral supplement even though B12 orally is non toxic in any amount, and people could just take the damn stuff and see if they feel better.

So given that insulin is a hormone and we especially want to test for hormone levels prior to replacing it, surely they test for insulin levels prior to prescribing it, right?  Surely they test the people who are on it to make sure they are getting the proper dose, right?  Surely they care at least a whit about what our insulin levels are, right?

The truth is, while there is at least some insulin testing done, although not a lot, the goal here is to see if you are producing at least enough, to rule out type 1 diabetes.  As long as you are making enough, then all is well.  They don’t really care how much you make and in fact even if your levels are way too high they will consider giving you more or even a lot more if your blood sugar is too high.

So the two tests they use here are fasting insulin and c peptide.  The c peptide is particularly useful if you are on injected insulin because it isolates what’s made in the pancreas only, although if you are on insulin then even low levels of this aren’t going to mean that much as the pancreas can take the day off with all the injected insulin flowing around, there’s really not much need to make more, like there is if you don’t inject.

Dr. Kraft, who I spoke about in previous articles, and who is a pioneer in insulin testing, actually measures insulin levels throughout  the entire process of eating, from the initial ones after the consumption of glucose to after the meal has been metabolized and insulin and blood sugar levels settle in after the meal is completely digested, although this doesn’t mean either go down to normal though.

This is really what we should be doing, but again, no one cares about insulin levels, any more than a drug dealer cares about your drug resistance, here’s some more, it’s good stuff man, maybe you need a bigger dose but that’s OK.

Dr. Kraft and others have been clamoring for people to be screened for diabetes by having their insulin levels tested, and we know clearly that high insulin levels lead to insulin resistance, which very often leads to diabetes.  Not everyone with high insulin levels and the accompanying insulin resistance, which always goes with this by the way because that’s what high insulin does, ends up being diagnosed with diabetes, some can fight it off to the end, but the risk is extremely high here and more and more people are getting hyperinsulinemia and more and more people are getting type 2 diabetes as well, so you would think we would care about this.

  1. This is exactly what it happened to type 2 DM, since the “invention” of Insulin in the 1920´s. Then we thought why don´t we do the same in type 2´s, after all the “end goal” is to reduce glycemia to “normal” levels…..once again just treating the symptoms 🙁 This is how our current medical system works, not just treatment for Diabetes 🙁
    Excellent post, I can´t believe why this work isn´t being shared!
    Thanks for your posts!

  2. Thanks Sergio, yeah that’s what conventional medicine does, treat the symptoms, and often not too well. What’s really scary is how blind the profession is to concerns about hyperinsulinemia, and the public as always just plays along, with no one able to see past the quarterly A1C tests. Thanks for the comment!

  3. Sergio, we do know that hyperinsulinemia precedes type 2 diabetes, we know that this also causes insulin resistance, and we also know that insulin resistance is a significant factor in the manifestation and control of T2DM. Sadly though, there isn’t much out there as far as studies showing this is an effective screening test, because it’s just not done generally, apart from the work of Dr. Kraft that is. The problem is that we generally don’t care much about the conditions that lead to a diagnosis of T2DM, insulin resistance, metabolic syndrome, etc. However we just need to put 2 and 2 together to see that high insulin is a big risk factor here, the biggest I’d say, from looking at how it affects the progression of T2DM from beginning to end. We need more studies here but it’s clear enough from just what we know already. Hyperinsulinemia is a disease in itself even without the hyperglycemia it so often leads to. If you’re not familiar with the work of Dr. Jason Fung, he’s got lots of interesting things to say on this, and on hyperinsulinemia and obesity in particular, and if you haven’t seen his videos or read his blog I’m sure you’d find it all most interesting. Do a search for Dr. Jason Fung on youtube, or check out his blog, Thanks!

  4. Actually I did a quick search on this and did come up with a study for you. You can’t use glucose tolerance until you actually become glucose intolerance though, so it’s not a good predictor with normoglycemia, insulin levels are though. What is really striking about this is that it is more predictive than BMI, and that’s really saying something.

    The present study is a late installment of results of a large survey, inaugurated in the early 1980s, that called attention to links between hyperinsulinemia, insulin resistance, dysglycemia, hypertension, obesity, and hyperlipidemia (1,2). Basal insulin was the strongest predictor for progression to type 2 diabetes over 24 years. Whereas ethnicity and higher values of basal insulin, triglycerides, BMI, blood pressure, fasting glucose, and male sex were each predictive of dysglycemia 24 years later, in the multiple regression model, the most statistically significant risk factor was basal insulin, reinforcing its importance as a chief component and perhaps a dominant factor in the development of type 2 diabetes.
