Elizabeth - Last time I had Type A which means that I was able to control it with diet. They sent me to a nutritionist to help me understand how to plan meals and snacks so that I was getting the right balance of carbs and proteins. They prescribed me a blood glucose monitor and "sharps" (needles you use to prick your finger) and I had to prick my finger several times a day (first thing in the morning, then after breakfast, lunch, and dinner.) If I remember correctly, they didn't want my blood sugar to be lower than 90 first thing in the morning, or higher than 120 after meals. I had to keep a diary of everything I ate and all of my blood sugar readings, and send them in to my nutritionist once a week for several weeks until she was confident that I knew what to do and had things under control. Eventually they moved me to pricking my finger less (maybe 2 or 3x a day instead of 4?) because I was in a good routine. They said that if I was unable to control my blood sugar through diet, I would have to move to pills, and if that didn't work, insulin shots. Luckily, it didn't come to that because I responded very well to the diet controls and I was strict about doing what I needed to do.
I probably will waive the 3 hour test and just ask my doctor to work on the assumption that I have GD again if I fail the one hour test. I kind of feel like it's inevitable that I will have it again anyway, so I may as well skip that miserable test and just get started on the whole GD diet and blood testing thing now. I am going to ask for a repeat session with the nutritionist though, even though I know pretty much what I need to do. It's been about 5 years since I had to do it, so I could use a refresher.
Mary - that's funny that you had to watch people to make sure that they weren't leaving to go smoke and eat. I'm amazed that anyone still smokes when they are 6 months pregnant in this day and age, although I know some people do. There was a woman that worked in my office building that used to go smoke outside every day, all big and pregnant (much to everyone's shock and disapproval, of course. )
