Glucose Screening Tests During Pregnancy

TWO-STEP TESTING During the first step, you will have a glucose screening test: You DO NOT need to prepare or change your diet in any way. You will be asked to drink a liquid that contains glucose. Your blood will be drawn 1 hour after you drink the glucose solution to check your blood glucose level. If your blood glucose from the first step is too high, you will need to come back for a 3-hour glucose tolerance test. For this test: DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.) You will be asked to drink a liquid that contains glucose, 100 grams (g) . You will have blood drawn before you drink the liquid, and again 3 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 3 hours for this test. ONE-STEP TESTING You need to go to the lab one time for a 2-hour glucose tolerance test. For this test: DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.)

    Really, come on! Like I haven't struggled enough in this pregnancy already. The first sixteen weeks I was throwing up multiple times a day, I lost 11 pounds. I'm a super tiny person, I only weigh about 110, and haven't gained much weight at all and I'm now at 26 weeks. I had bacterial vaginosis in my first trimester too. It's just one thing after the other and I can't stop crying.
    What did I do wrong? Is it my diet? I'm a super healthy person. I exercise and watch what I eat. I'm just so damn frustrated right now. I failed with a 170.
    Someone please tell me what I should be doing better to not fail the 3 hour test. The one hour was horrific enough because drinking something that sugary made me feel super nauseous and I never wanted to do it again. :(

    Whether you're 110 pounds or 210 pounds, whether you eat healthy or eat cake for breakfast every day, you can still get Gestational Diabetes. It isn't something you develop due to your diet/exercise, although being overweight puts a pregnant woman at a higher risk.
    You didn't do anything wrong. It just happens.
    A LOT of women fail the 1 hour and pass the 3 hour. There's a lot of mixed information regarding fasting, not fasting, what to and not to eat prior to the 1 hour, etc.
    Follow what your doctor or phlebotomist instructs you to do and if you have GD, you'll get a positive result, if you don't.. you very likely will get a negative result there as well. It's difficult to inaccurately fail the 3-hour test.

    Thank you for the response. I really had no idea what causes it, and knowing it's not my fault makes me feel a lot better.
