A Guide To Blood Sugar Levels

(Q) My doctor says that my sugar level was 8.0. Can you tell me if this is very high or just above normal? (A) Usually blood sugar levels are tested in the 'fasting' state – when you have not had anything to eat or drink for eight hours. The normal range for fasting blood sugar is anything from 3.0 to 5.5 mmol/L. If you have not fasted, the normal range for random blood sugar is between 3.0 and 7.8 mmol/L. The body can usually keep the blood sugar within this range despite variations in food intake and energy expenditure, but if the blood test is done very soon after eating it is possible it may be slightly above. Other conditions which may temporarily cause increased blood sugar readings include acute infection, trauma and physical or psychological stress. In such cases the raised blood sugar may not be indicative of diabetes and the test should be repeated once the condition of circumstances have stabilised or resolved. If your blood test was done immediately after eating a large amount of carbohydrates or if you had a concurrent health condition or circumstances such as those described above, this might explain the result being mildly above the range for random glucose. But if Continue reading >>

    Hello there
    I am a gestational diabetic mother to be as well. The amount of conflicting information out there is staggering to be honest. Also the differences between American and British approach is surprising as well. I was reading an American website regarding gestational diabetes and in there the normal levels are given as
    Fasting 60-60 (3.3.)
    Before Meals<=95 (less than 5.3)
    1 hr after <120 (less than 6.7)
    0200-0300 am between 60-120 (between 4.4 and 6.7)
    I will post the address for this site again for you as soon as I find.
    However, my diabetic team gave me completely different limits. They did not bother with lower limits much but they said lower than 5.6 when fasting and lower than 7.8 1 hr after meals. When they talked to me about insulin they said if my blood glucose was measuring lower than 5.3 not to drive but to have something to eat before I drive. That's what they told me. Nobody mentioned about what was a hypo as such. 3.9 before breakfast is just only a tiny bit lower than what I get really. I get 4.2, 4.3 often in the mornings.

    As this is a UK site for Diabetes here is a link to the information about Gestational Diabetes from this sites Community pages with information about levels and much more. The usual advice is between 4 - 7 mmol/l so 3.9 is just a tad low. Not too far out though.
    You should in any case discuss the acceptable levels with your Diabetes Team as there may be reasons, medical or otherwise why you should adhere to a different set of standards. As the health of both baby and Mom are paramount do not do anything without first discussing it with the HCP's.
    That is what they are they for........
