I declined it with my first pg bc besides being over 25, I had none of the risk factors for it. DS was an average weight, and even though I gained 45 pounds myself, I went back to my "normal" weight within a year of him being born. So I'm planning on declining it this time, too. I don't eat processed foods, period, and I've been biking 10+ miles a week at this point.
I think it's like a LOT of things with maternity care in this country - it goes overboard by insisting all women test (the rate of GD is actually under 5%, but the way the current test is run, your chance of being diagnosed is somewhere between 3-15%). Not to mention that different providers have different cut-offs of what's considered GD, and that your body processes glucose differently at 24 vs 28 weeks. Until it's standardized enough that the results are consistent accross the board, I don't see what the point of testing for it is (for me, personally, that is).
Henci Goer has really good things to say about GD testing, this is a good article to read: http://www.ivillage.com/gestational-...ach/6-a-129188
. And she writes more about it in "Obstetric Myths and Research Realities", though I can't seem to find it online right now, this is an excerpt that was in the book: http://www.gentlebirth.org/archives/gdhgoer.html
I also find it interesting that other countries don't routinely test for GD the way the US does - I think things would be much, much better if the actual importance of nutrition during pregnancy was taught and tracked than making every pregnant woman drink some glucola (and hyperventilating when some of them turn it down...).
