Gestational Diabetes...failed the three hour Glucose Tolerance Test

Answered on August 19, 2014
Created April 21, 2011 at 4:38 AM

I have a question and Im hoping someone can shed some light on this for me. My appt with a Dietician is not for a while and I would like some answers now. With my first pregnancy, I failed the one hour glucose test so they referred me to the 3 hour test. They told me to eat a diet filled with carbs and I did that and passed the three hour test. Now with my third pregnanct, I failed the one hour test. I forgot how long they told me I should not eat for and I ate at noon and my test was at three. I also ate something really small, I think a small croissant with a piece of turkey. So my first question is did my glucose level go up because I took the test three hours after eating something really small?? My other question is that they didnt instruct me to carb load for the three hour test this time (different Dr) so I actually ate very little the day before bc I was so stressed. I ended up with a normal fasting score of 89 but failed all the other scores afterwards. Now I am diagnosed with GD bc my scores were so high. Any input will be appreciated.

So far my readings are pretty good..knock on wood..Hope it stays like this bc they informed us that the more you get close to delivery, the more insulin your body has to make.

Well...I have an update. I was at the Dietician today and I asked about the carb loading diet and she said they dont recommend that anymore. ALso, I got my meter and started testing today. They asked me to test 7 times a day. So far, my numbers are within range thank GOD!! SO, we will see how the rest of the week goes.

My fiance is pregnant so I researched to make sure she would ace the glucose tolerance test. I found this blog post which explains why low carb eaters can actually fail the glucose tolerance test even if they're not diabetic. Hope everything works out for you.

In general, if you low carb, then you would add 10 points to adjust the score. See bloodsugar101 for details on conducting your own at home OGTT.

Agree about carb loading if u normally eat low carb... If you ate a low carb diet over weeks, it can in theory cause a false high bg score due to downregulation of insulin receptors. however, fasting for a day wouldnt cause this effect. Only prolonged low carb/fasting.

I did come across this website...this where I read that fasting for 12-14 hours can make the OGTT give false positive. Also, it talked about the carb loading. As I said the first time I was pregnant, I passed the three hour test when I carb loaded, this time I didnt carb load and failed. I know each pregnancy is different but I think its something to consider.

you need to be absolutely tested.....and if you plan on having another baby in 2 yrs no doubt. Recently a study was just published that shows high autism risks for a second baby born to a mother after a low post natal D level was found. I think it was in the Journal of Pediatrics within the last six months if you want to google it.

Dr k. You sir are a dick. Im not " mixing things up badly" Im assuming she does not have GD but is failing the OGTT secondary to a vlc paleo lifestyle. The question I asked Robb, and his reply, warrants merit here as it builds a case for using alternative more reliable testing. I've bitten on your inflammatory remark once. It wont happen again. Quit trolling these boards. If you have advice to offer do it. If you are just going to make negative comments, go visit 4chan. Trust me when I tell you Im not the only person who holds this opinion of you.

gestational diabetes is a warning sign. It means mom is leptin resistant and very likely has a very low vit D level She is also at high risk of developing type two diabetes in the future as is her offspring. The child is likely also leptin resistant if mom was at pregnancy. Not good at all.

Thats what Im going to do. For my peace of mind, I am meeting with the Dietician on Monday and will be getting the glucose meter. My fasting # was 89 so if I had a problem wouldnt that number be much higher? What stinks is that the first meeting with the Dietician is a class setting and I would much prefer to be one on one bc I have a ton of questions.

I swear, that test made no sense to me. When I got pregnant I avoided sugar and grains besides some rice and potatoes like a hawk but at the time I didn't know about Paleo yet. So then they give me a bottle of pure sugar water, something I wouldn't DREAM of taking in and expect that to give realistic results about how my blood sugar behaves on a day to day basis? So freaking weird. I wouldn't have followed that stupid GD diet even if they had found my blood sugar to be high. Just looking at it, it was ludicrous the amount the fructose it allowed.

I'm assuming you've been doing the low carb thing for a while. If so...

When you go low carb, your body will adapt. It assumes that there is no glucose around and since your brain needs glucose, it makes your muscles insulin resistant. It's a protective mechanism your body triggers when in a glucose scarce environment. Since your muscles are refusing glucose, it frees up glucose for the brain.

All you have to do is load up on carbohydrates for a few days and your insulin sensitivity will return.

...

Oh yeah, I forgot to mention...

The reason you failed the test, assuming your not diabetic, is because since your muscles are refusing the glucose, your blood sugar shoots up.

The test is archaic ....assuming you are paleo and have been for a while it would behoove you to get an a1c test to help build a case and show that you do not have GD. We had the same issues, I actually wrote into Robb Wolf and asked him. Here is his reply: http://robbwolf.com/2010/09/06/gestational-diabetes-what-constitutes-low-blood-sugar/

Looks like someone else already linked to Robb Wolf's article about it, but I'll do it again just to emphasize it: http://www.robbwolf.com/2010/09/06/gestational-diabetes-what-constitutes-low-blood-sugar/

These tests are actually dangerous to the mother and fetus if the mother is already fat-adapted. Don't follow stupid convention and take some test that you don't need to. My wife and I dropped our Doc and switched to Midwives when they tried to play the "you don't love your baby" card when we refused the test last year. The test contains no useful information, so the results don't matter. Also, don't try to ramp up your carbs just to pass a test. That's also not good for you.

This woman writes a blog about her Paleo pregnancy, and she did some sort of alternative GD test that didn't involve large carbohydrate intake:

Start religiously monitoring your own post-prandial glucose (1 and 2hrs after a meal).

Keep a record for 2-3 weeks and then show to your doctor, if it's all good they should revoke the diagnosis of GDM.

Take some magnesium too.
