Did you have 1 placenta or 2? 1
How many weeks when you delivered? 36
What were the weights of the babies? 4lbs, 6 lbs (keep in mind these were TTTS babies, which skews things quite a bit for the donor)
Were you taking insulin? nope
If you did not take insulin, did you keep to a strict diet? Yes, but not a diabetic diet--I was following Barbara Luke's plan as much as possible, with the addition of 3x daily protein shakes (on recommendation of one of the doctors that I consulted with about the TTTS). Though, since I was having to pack as much nutrition as I could in every bite because it was an overwhelming amount of protein/other nutrients needed, to be honest with you I was not sucking down Mickey Dees Milkshakes and gobbling bags of potato chips either.
I had GD with my firstborn (singleton) as well, never treated with insulin, and didn't check my diet.
A lot of women (myself included) bomb the challenge test, and have higher than normal "fasting" levels, but when monitoring during the day it's discovered our blood sugars are pretty on target and very stable.
almost 10 years out from my first case of GD, I have no sign of type 2 diabetes even though I'm obese, and my numbers during the day are stable (I still test for a couple of days a couple of times a year, just to monitor myself since I know I'm at higher risk for developing the disease at some point in my life).
I know the initial diagnosis and OMG I Failed!! can be overwhelming (esp. if it's accompanied by aggressive nurses doctors jumping into your face and down your gullet) but try to relax, try to not assume the worst case, wait until you've monitored for a couple of weeks. It's likely your blood sugar will be stable and you'll never have to do insulin (most people don't). But...if your numbers are at dangerous levels, you need to educate yourself on the risks to yourself and the kiddos. Yes, it can increase birth weight for babies--but that may not be balanced out by other risks. I would get information first--don't rule treatment options out OR in until you're actually there.
