    Can non-diabetes get high fasting results?
    An_254162 posted:
    I can't seem to find the answer to this anywhere. Can non-diabetics get high fasting (or even post-meal results) if they eat an excessively high carb/ sugar meal?

    As an example, after a high carb dinner (plate of pasta) with half a dozen oreo cookies as dessert, the person has a fasting blood sugar level 114 the next morning.

    In general though, does blood sugar go outside normal range for non-diabetics/ "normal people" if they are eating excessively unhealthy for certain meals? Of they still remain within the normal ranges? (though we know that kind of eating long term would have some sort of repercussion).

    Thanks for any responses and, especially, for pointing in the direction of any research or medical opinions that shows an answer to this question.

    Here's what I know. In cases of trauma, a non-diabetic can have high blood sugar. I know of several people who had strokes who had one time only very high glucose levels when they hit the ER. 10 years after the stroke there has never been a high number since. I also know that it is common to give severely brain injured patients insulin as their blood sugars also go up. They are not diabetic. I know this was the case with my pancreas donor. I know that a friend who is an ER doctor talked about kids with fractures who had high glucose which permanently returned to normal after they were treated.

    That said, a non-d will not have high fasting levels or high post meal levels no matter what they eat. That's kind of the point. Higher blood sugar levels in the absence of trauma means diabetes.

    Thank you, Cora! That's very helpful information.

    In my opinion, it depends who you ask...

    Ask a person with an A1C of 4.9, they may say, "No". Ask a person with an A1C of 5.9, they may say, "Yes, it's possible".
    For me, there is no such thing as "non diabetic" because I believe everybody walks the "spectrum" of diabetes. Perfect example is gestational diabetes and diabetes reversal after gastric bypass surgery. How does one reconcile the "transition" from "diabetic" to "non diabetic" or vice-versa? Bad luck, good luck?
    leftyplayer replied to brunosbud's response:
    brunosbud, that's an interesting perspective. I'm wondering if that gestational diabetes and even gastric bypass surgery could be considered to also be traumatic in a sense and maybe also fit the information by mrscora regarding trauma as a time when "the line gets crossed" (in the case of surgery, cross in a good way I guess). It's all food for thoughts. So far, though, seems like what you guys are saying is that that line between "normal" and "diabetic/pre-diabetic" doesn't get crossed too easy by the average person on an average day?

    When I was in school for nursing and medical assistant, one semester was devoted to labs and at-home testing. There were seventeen of us in class ranging in age from 18-60. Our professor had us all take each other's glucose readings on the same glucometer. No one in class was diagnosed as a diabetic at the time. Nearly every single person registered 82 or 83. It was a random test in the morning around 9 or 10 a.m. As I said, totally random. We don't who ate breakfast (or anything) or snacks when these were taken.

    On the average a non-diabetic will have a reading of 85. Everyone's glucose will rise after a meal of heavy carbs. Out of curiosity, I tested my husband on two meters after he had eaten a heavy carb load. It was about 45 minutes after. He registered a 152 on one meter and 153 on another. Two hours later, he was in the low 80's. I wanted to see how high his levels would go.

    I am a diabetic, and if I had eaten what he ate, my BS would have been in the 600's. That's me though. My body does not tolerate carbs. Any carbs. I need two insulins to stay within the normal parameters.

    Certainly, there are various traumas that will give rise to high blood sugars. It become worrisome when a non-diabetic has blood sugars that don't return to the normal range two hours after eating a meal heavy in carbs.

    I would say that no, the line would not get crossed too easily for the average non-diabetic and diabetic on an average day.
