I was borderline barely failed my 1 hour and 3 hours tests. I checked my blood sugar 4 times a day the rest of the pregnancy. I was really upset at first. Then I got used to it and realized having the GD did have some benefits:
1. I ended up eating really, really carefully during the 3rd trimester and actually lost weight instead of gaining (DS was still 8lbs 4oz so it did him no harm!)
2. Each week I got either an ultrasound or a non-stress test so it was extra reassurance at the end that LO was absolutely fine.
Just don't google Gestational Diabetes. It lists all sorts of horrible side effects. According to the ladies teaching at the diabetes center, most of those are really only a risk for people with serious diabetes prior to getting pregnant. There's no real differentiation in the literature between true diabetics and people with GD. Most of us just have a be a little careful about when/how much we eat and have perfectly healthy LOs.
DS's sugar was slightly off when he was first born but he had 2 oz of sugar water and was fine. He's still perfectly healthy 16 months later!
