I had GD with my first pregnancy and controlled this strictly with a diet. Currently I am 7 weeks and 3 days pregnant with my second and had GD with my first. I am not a type 2 diabetic but are insulin intolerant. My recent fasting sugar levels in the morning ranges between 6.2 to 6.7 (take with a Accu-Check Active). The average blood sugar test done by the doctor when I was 4 weeks pregnant was 6 which she said was normal. My sugar levels 90 minutes post meals range is normally below 8 (again my doctor indicated this is should be below 8) as I strictly control this with my diet but if I don t limit my carb intake and eat the wrong carbs /â??new carbsâ?? it shoots up to about 9. What I would like to know is: (a) what the upper limit for my bloodsugar should be 90 min after meals (b) when should the test be taken after meals: (i) 60minutes after starting a meal, (ii) 90 minutes after starting a meals (iii) 60min after finishing meals? (iv) 90 min after finishing a meal?
Hi there,,Previous gestational diabetes makes you at a higher risk for gestational diabetes in this pregnancy. You need to do the 75g oral Glucose Tolerance Test to determine if you have it in this pregnancy or not. This will more accurately determine your risk of gestational diabetes than the Accucheck readings or the post prandial 90 minute test.The OGTT value of fasting is 5.6 mmol/L and at 2 hours is 7.8 mmol/L, values above these indicate gestational diabetes.Once gestational diabetes is diagnosed you can monitor your blood sugars daily by accucheck, documenting both fasting and post prandial levels. The fasting values should be less than 5.3mmol/L; the 1 hour post prandial should be less than 7.8 mmol/L; and 2 hour post prandial should be less than 6.4 mmol/L.The 90 minute is not routinely used to monitor the values nowadays.Hope this helps.Regards.
