Glucose tolerance test false positive?

Question

Hi ladies, I failed my 3 hr test and my obgyn wants me to go to a maternal-fetal specialist. I decided to start checking my glucose levels since my appt is until the 5th of May. I am attaching my readings for today. I did not change anything on my diet. Is it possible to get a false positive with these tests? I am vegetarian and really do not eat many processed foods, although I did start my pregnancy with some extra weight (and I am 37 yo). I started logging my meals and I rarely consume 100mg of sugar a day. So I am wondering if it's possible that the glucola just threw my body out of whack. Any insight is appreciated!

Answer

I've read that quite a few women that are on low carb diets already before and during pregnancy often fail the test because their bodies aren't processing that many carbs/sugars on a daily basis, especially those women on a primal/paleo diet. Your body is used to tons of protein and veggies and then they pump you full of sugar and make you sit in a chair and don't allow you to do anything to help your body process the sugar and expect you to pass the test. There are a few good reads on the subject, a blog called Mark's Daily Apple has a good forum posted with women on there talking about the same issue.

Honestly tracking your sugar just to be safe is a good thing. If your numbers stay consistent like that, there will be no need for any medication. I'm the same, except for my fasting numbers. I can eat a lot of things I'm not supposed to, get up and load the dishwasher or do one load of laundry, and my number is just fine. My fasting number is a different story; my hormones hate me, so I'm on insulin to control it, but that has nothing to do with my diet.

Answer

From my experience, sometimes not getting enough can also affect your bs. 
When I first tested I was in a state of ketosis because I was lacking in carbs and proteins. It was about finding the right balance for me at first. I still struggle with dehydration (which also affects my numbers) but the food balance is easier now because I was given goals. I eat a certain number of carbs & proteins per eating and a target of calories per day, and spread things across 5-6 small meals. But that's for me and it just depends on how your placenta and pancreas are communicating.  
While I don't think you have a false positive, I'm no doctor. This is my long winded way of saying that there are factors beyond how you eat that can affect your blood sugar. 
I'm also over 35 with a less than ideal bmi and I was diagnosed at about 13 weeks (I'm now a few days shy of 25weeks). 
Don't worry momma, it will be fine. Hear what the specialist says and then take it from there. You'll do great. :)
