Insulin resistance/function

Just have a few questions re insulin resistance/function. Would be grateful for any advice.

1. Was thinking of booking an insulin resistance check through medi checks. If fasting blood sugars are fine but post meals are high, would it be best to go for the test after eating something rich in carbohydrate to see how much insulin your body produces?

2. Do all or most people with insulin resistance have high blood pressure?

3. Would all or most people with insulin resistance have abnormal liver function test results?

4. Does eating lots (And I mean lots) of dairy contribute to insulin resistance? I know carbs are the real killer but wondered if dairy can play a part.

5. Is it possible to have a sloppy insulin release e.g. late release, slower release but not have insulin resistance?

Cheers

I doubt this will tell you anything useful as it all depends on exactly what you ate, how many carbs, which type of carbs, fast acting, slow acting, something in between, glycaemic load of the whole meal, how much fat, how much protein. So on and so forth. I guess it would be impossible unless you did the OGTT with 75g pure glucose on a fasting stomach.

I don't know, but I didn't.

Unlikely. My liver tests have all been superb.

The foods that play a part are the ones that trigger a large insulin response. Obviously carbs. Fruit is also very insulinogenic. Butter, cream, cheese are fine. (In fact butter doesn't trigger any insulin response). This is a table of some foods other than carbs and their insulinogenic properties. https://public.tableau.com/profile/christoffer.green#!/vizhome/InsulinogenicFoodData/Dashboard1

Lactose intolerance is the most common intolerance and, for those of us who are intolerant, dairy foods are not fine in terms of their effect on blood sugars. If I ingest dairy in anythng other than small infrequent amounts, my sugars are much more erratic and out of range

As far as I know the Insulin Resistance check from Medichecks is a fasting test.

Certainly the one I had was.

The web site is very unclear and I had to ask them before I found out what was needed.

After you book the check you get a lot more information.

Worth looking at https://en.wikipedia.org/wiki/Homeostatic_model_assessment which gives you a formula. As you can see it is your insulin x your glucose divided by 22.5.

If you have the blood drawn after a carb heavy meal both your insulin and your blood glucose are likely to be high, which would give a very high IR result. A non-diabetic would get a high result under the same circumstances.

I thought the calculation would be along the lines of blood glucose divided by insulin so that it didn't matter when you took the sample. However for the Medichecks test it is strictly a fasting test.
