What Is Considered A High Blood Sugar Level For A Diabetic?

Without diabetes, your blood sugar should stay within the range of 70 to 120 milligrams per deciliter. But if you are diagnosed with diabetes, a more normal range for you may be between 80 and 180 milligrams per deciliter, according to the Juvenile Diabetes Research Foundation. Clearly, anything outside of this range is dangerous for a diabetic, and when it gets to a certain level, you may require immediate medical attention. Video of the Day Anytime blood sugar is more than 240 milligrams per deciliter, it’s a cause for concern among diabetics. It is particularly dangerous if your sugar is this high before a meal, since consuming any food would probably cause it to rise even more. When your blood glucose is above 240 milligrams per deciliter, it means your system isn’t getting the energy it needs from glucose and could start breaking down fats. Your body starts producing ketones, which stem from fat deconstruction, possibly putting you into ketoacidosis that could lead to a diabetic coma. If your blood sugar surges to over 300 milligrams per deciliter, contact your physician immediately, since it could be life-threatening. Continue reading >>

    A work colleague was taken ill at work on Friday and taken off to hospital by his dad.
    He is still in, apparently his heart rate was high, but he has also been diagnosed as type 2 diabetes, his blood sugar upon admission was apparently 22.
    The mrs has type 2 also, but I have never seen her this high.
    The chap at works speech got progressively worse over the preceding couple of days ( has does not have the best speech, so we did not notice initially) my thoughts when he was taken away was possibly a stroke (although we did the basic checks and all seemed fine)
    How dangerous is 22?

    22 as a one off is not dangerously high but if it remained high there is the risk of a diabetic coma (diabetic ketoacidosis) which I life threatening.
    I suspect if your colleague didn't know they were diabetic then they have probably been running high for a while and that's why they were experiencing the symptoms you describe.

Its dangerous but not life threatening - DKA takes quite a while to set in, when my brother had a random blood glucose of 22, I rushed him into A&E, 15mins later, he was on an insulin drip.
