Where I am they start the test at 9am, so you only need to skip breakfast. The drink I had was sweet but also carbonated/fizzy and not thick/syrupy at all, pretty much like a soda, so I didn’t mind it so much. I took my laptop with me to distract myself for the time between them taking the bloods. 

Don’t cheat and eat something before because then you’ll probably just end up with a high score and an inaccurate result or have to do it again. 

ETA… Another thought – have you tried asking to do the 1 hr test again?

I skipped the 1 hour and went straight to the diagnostic test because I didn’t want to waste my time going to the lab twice.  Here its a 2 hour test.  Overnight fast, blood draw, drink 75mg of the orange stuff (which I liked.  I must be gross.  But I had no problem downing that sucker in under a minute.  I was given 5 minutes to drink it.  But I was thirsty!) and then a draw at 1 hour and a draw at 2 hours.  

I was STARVING.  But I’d booked my appointment for the very first available time slot in the morning.  I was ok until about 30 minutes in, then I started feeling gross.  At the 1 hour draw they let me lay down in the EKG room until my 2 hour draw.   I really wanted to vomit.  And I was clenching my teeth to keep from losing it.  If I threw up I’d have to come back to redo it.  Laying down helped a lot. 

I was told to bring a snack with protein and carbs to eat after.  I felt better once I got some food into me (and some water.)  But I did go home, ate a huge lunch and then crash on the couch for the afternoon.  I slept for hours.  But I felt fine when I woke up. 

I passed with flying colours.  Not even close.  So next time I’ll just do the screen to start.  (I don’t have any family risk factors except that I come from a long line of women who have birthed 10 lb+ babies.  So there was some concern that there may have been undiagnosed GD in the past.  Doesn’t appear that way though, maybe we just grow big people.)

My advice, don’t do it. Purchase a glucometer on Amazon for like $20 and test for a week every day one hour after breakfast or lunch. This is a much more accurate and healthy way of testing. Record all your numbers and give to your doctor. I did this with two pregnancies thus far and my ob wishes everyone would because it’s so accurate. And it’s not a bad idea for people to tedt once A month or so anyways pregnant or not.

I had the test last week, went in dreading it as friends had told me how awful it was. I really didn’t think it was that bad to be honest. I was worried about being super hungry too. My appointment was at 7:30am. So you have the drink very soon after first test (drink tastes just like a very sweet soda), once the drink hits your bloodsteam I think it helps to ease the hunger!

Don’t cheat, and don’t stress – you’ll be fine!

I had my one hour test last month and was allowed to sip on water while I waited, are you able to at least do that? I had to do the 3 hour test with dd and they offered water then too. I wasn’t allowed to chug water, but sips were ok.

Can they give you the drink to take at home? That way you can fast, and take it the moment the fasting time is up, to avoid any in between time of waiting for a lab To open, driving, checking it, etc.. 

If you can do this, I would go to bed early, set an alarm, chug the drink and then nap for a bit and go to the lab right after they open.

Cory_loves_this_girl:  they’ll take a blood draw to check your fasting sugars before drinking the glucola hence why you can’t do it at home.

Seriously though, it’s not that bad so don’t psych yourself out before you even get there!

Cory_loves_this_girl:  If you’re allowed water, it’ll be a lot better.  I wasn’t allowed anything by mouth after 9pm the night before (not even water) and nothing during the test.  

And for the same reason Kemma:  mentioned, it couldn’t be taken at home.  I had to have a fasting blood draw before drinking the orange stuff.  (Also why you shouldn’t eat and try to cheat it, it’ll throw off your fasting draw.) 

Honestly, it wasn’t so bad.  It’s only a few hours.  And when I was doing it I was at my hungriest point of the pregnancy.  I usually ate within minutes of waking up!  I wouldn’t want to do that every day, but for one day it was manageable. I had the day off though, so I didn’t have to worry about going to work afterwards.

They should have told you they would be doing the glucose test, because they usually want you to fast for the one hour, too. But DO NOT cheat for the three hour, so don’t eat and if they say not to drink water, don’t do that, either. The whole idea of this test is to do what is best for the baby and for your own health, so don’t cheat the test in any way. You want accurate results, even if it is temporarily uncomfortable for you.

I did NOT fail my one hour glucose test, but they refused to believe the baby could be measuring so big if I was not diabetic, so they had me take the three hour test, too. I passed that as well, but they STILL did not believe that I was not gestationally diabetic, so they did a finger stick test at EVERY. SINGLE. VISIT. after that. I never tested outside of normal ranges, and the dates on my pregnancy were extremely accurate (we were TTC); I just had a huge baby (11-1/2 lb at 38 weeks). The three hour test isn’t exactly fun, but it isn’t as bad as you might be anticipating.

If it makes you feel any better, I had by chance fasted before the 1 hour and failed. Passed the 3 with flying colors. I fasted before it but I didn’t really follow the diet they gave me for the 48 hours before. It wasn’t as bad as I thought it would be, but definitely switch arms between draws!

Cory_loves_this_girl:  I’m not sure if this is an option for you, but the lab I went to had private rooms with beds. When I did my 1 hour test they apologized for not having a room available for me. If they did, I could have had a good nap. Maybe yours has a room too, and a nap could help bide your hunger?

My 3 hr test wasn’t as bad as I thought it would be. Sipping on water helped and I distracted myself with the wifi and my laptop. I would suggest not doing anything to try to affect the results. Hopefully you don’t have GD but if you do it’s good to know. I was diagnosed with it and at first was so upset and surprised. I had no big risk factors. But I was able to control it with diet and exercise. My son was born perfectly healthy and the diet helped me control my pregnancy weight gain. So I’m actually glad I found out about it. Good luck!
