I am just having a hard time wrapping my mind around this. I have spoken with the nurse...three times, and got the same answer every time: NO WATER AT ALL from midnite until the test is completed the next day. This means I will have to go about 12 hours with no water?
This just seems wrong.
Am I just being difficult?
A - Dehydration can screw with your test results.
B - Asking a pregnant woman to go 12 hours without any sort of hydration is foolhardy and irresponsible.
My textbooks indicate the the GTT is typically done after a 12 hour water only fast.

But I never had this test done so I don't know.

I was specifically told that water was fine during the fast.
I was told only to drink "sips" of water during the 3-hour test (I guess if I really guzzled a LOT of water it could dilute the solution in my stomach or something like that?) but nobody ever suggested that I should dehydrate myself! Yuck, the test is bad enough as it is.

I took the 1 hour last week and the lab told me I could have a few sips of water if I needed to, but not to eat or drink much (They said I could have a cracker or two, and a little bit of water) but too much could alter the test results.
I am hoping the nurse is just wrong, and my OB says I can have water, otherwise I think I may be in the market for a new OB!
And I agree with OP, drink water! That's ridiculous.
As I understand it, the problem with the A1C test is that if you actually have Gestational Diabetes it won't have been present for the past month (as opposed to underlying pre-existing insulin resistance/"prediabetes", or undiagnosed diabetes). GD develops as a maternal response to placental hormones later in pregnancy, and so an average can be very inaccurate. It also typically increases over time, and peaks a few weeks before birth (when the placenta matures). The whole duration of the condition is so short and if your goal is diet control (if that is possible), you'd want to know early and figure out the diet as soon as possible, not wait until you've been abnormal for a month first.
IF you "fail" the 3hrGTT you will learn a *lot* through self-monitoring about how your body is processing and handling sugars and carbs from your real food because you'll be logging everything you eat and testing 4x per day.
Anyway, just my experience from having GD and diet controlling. I passed a 3htGTT at 20 weeks and then failed one (borderline) at 25. So, not sure what an avg of that month would have shown.
Hope you pass! Definitely don't refrain from water- that is wrong and unhealthy.
