GDD screeningI too discussed this in detail with my midwives. What they do differently is have you eat a completely typical meal for YOU, nothing extra heavy on the carbs unless that is what you typically eat, then they test your blood at the regular prenatal visit 2 hours after the meal. If the results are in any way questionable they leave a glucose moniter and you test your blood 6 times, once before and once after breakfast one day, lunch the next, and dinner the following. In all my pregnancies it has been done differently, but this one makes the most sense because it shows how your body naturally copes, not giving it anything artificial which skews the results. One thing I have heard though is that the risk is not just in having a large baby, but that the baby is at a greatly increased risk of being harmed by the increased insulin, which can possibly be fatal. Personally I don't feel at risk because I am measuring perfectly right for my dates, have no sugar spilling in my urine, have no family history, and even though my third baby was large, he wasn't abnormally so. Still, I guess to be safe, and since it doesn't do anything invasive to my baby, I'll do the simple version of the test.
