I am hypoglycemic and have been since I was a teenager. Basically, the way it was explained to me is that our bodies use insulin and sugar faster then the average person. My pregnancy makes the side affects worse, as it does with everything else. So I get more headaches, lightheadness, and feeling faint. I need more sugar.
Basically, this is what I have to do. I am suppose to eat 6-8 times a day. Small meals and snacks. I have never worried about calories because I always eat too many anyway. The snacks should be things like fruit, cheese and crackers, not a lot of junk food. I also have to always have something to snack on with me, in case my sugar drops while I am running errands. I always have a juice or candy in my bag. I have had a few close calls, where I didn't and couldn't get something immediately, and almost passed out.
I have found, and of course each body is different, if I stay away from sugar, my sugar levels tend to level out. If I go through a phase when I eat a lot of candy, like around the holidays, when I don't eat it, I go through a week or two of crazy sugar highs and lows. The doctor told me that if I stay away from lots of sugar, diabeties should not be a problem later. It also makes us crave carbohydrates. Which is terrible while I am pregnant. Towards the end of my last pregnancy and at times during this one, I would eat a meal that did not have enough sugar, and I would have to eat something with sugar afterwards because the meal did not increase my sugar level enough. I would still feel yucky. Bacon and eggs with milk doesn't have enough sugar for me. If I add OJ or jelly toast, I am ok.
I had a terrible time during the first tri-mester. My sugars would hit lows even though I just ate. Now that I am towards the end of the second, they seem to have leveled out quite a bit. I think it had to do with the hormones that give us morning sickness. So you should start to feel better as you progress.
What type of diet did your doc put you on? I would love to know since, my docs never made a big deal out of it. They always told me to eat more.
Good luck with the pregnancy. For me this has been an easy side affect to mange. We get to eat more and have an excuse!!!

Don't worry about the diabetes stuff till later just enjoy the pregnancy now.
