I had GD during my first pregnancy. I had perfect GTT results about 8 months after birth. Now I am pregnant with number 2 and OB suggested that I start the diet now just in case. I am not really overweight.
So my question to you is, did you alter your diet during your second pregnancy prior to testing just in case? And do any of you know the chances of having GD the second time around if you had it the first time? If you started checking your glucose on your own, at what point to did you start to notice high numbers again?
In general, I make pretty good food choices anyway. My ms has been bad this time however so I am allowing myself to eat whatever makes me feel ok which includes a lot of fruit.
Re: Second time moms who had GD the first time?
With DD1 I was diagnosed at the typical 28 weeks. My GTT at 6 weeks PP was perfect, and I got pregnant again when DD was not quite 11 months old. I started diet and testing on my own at 11 weeks after failing the 1 hour. It was clear already that I was having issues with fasting numbers at that point. I was officially diagnosed at 13 weeks after failing the 3 hour.
I don't know the exact statistic of how many women who have had GD end up with it again, but there's a pretty decent chance you'll have it again. Some people get lucky and don't though, or at least don't develop it early as is common in second timers.

I had GD with my twin pregnancy. I'm now 21 weeks pg. I started loosely following the diet as soon as I found out I was pg. I didn't count carbs, but I would pair a bard with a protein and made sure to eat every 3 hours. I didn't check my blood sugar level.
I failed my 1 hr GTT but passed my 3 hour two weeks ago. I retake the 3 hour again at 28 weeks.
I did research and found that there is a 33% chance of developing GD if you had it with a previous pregnancy. If I can find the study again, I'll post it.
Here are two studies. One says there's a 35% chance of GD with a 2nd pg and the other found a 41.3% chance.
