I'm pretty on the fence about this one. Did you or are you doing this test? On one hand, I have a family history of Type II diabetes. My first child was 9lbs and maybe half an oz (which some practitioners consider large enough to be a risk factor for GD and some don't - I certainly don't consider that to be an overly large baby).
At the same time, during this pregnancy I haven't gained a bunch of weight. I'm actually slightly under my prepregnancy weight still due to weight loss due to morning sickness. I haven't had sugar spill into my urine. I don't eat perfectly, but I do eat healthily and regularly get exercise. I've never had a high blood sugar test. I'm under 25 years old.
Mostly, I think it's not great for a pregnant person to fast at all. And then I think it's particularly not great for a pregnant person to fast and then consume that much sugar. If the GD I had was mild enough to be controlled by lifestyle changes, I'm already mostly living that. It would risk me out of a homebirth and set me up for a cascade of other interventions. I've also birthed an "overly large" baby before with no complications either during the birth or for her after the birth, making me wonder if the standards for normal are too strict. I worry about the validity of the standards they use for the testing - the sugar levels they consider acceptable are lower than if I were a non-pregnant person trying to learn if I was diabetic even though it's known that pregnant people metabolize sugar less efficiently due to hormones.
So, I'm not sure what I want to do. I'd love to hear what you mamas think about the test and what their choices were.
