I had it with my first pregnancy. I had to take insulin. Some people feel like if they have to start using insulin it is because they are doing something wrong- DON'T fall into that trap!
A high fasting blood sugar generally means you ate too many carbs the night before. Watch your carb portions carefully! Now that you are on insulin you will have to be extra careful that you have enough, but not too much!
As my pregnancy progressed, so did my insulin.... you see, the diet restrictions caused me to stop gaining weight, even though I was trying to eat enough... the doctor would tell me to eat more, the dietician would say that I needed more insulin... and so on. Even though I followed my plan to a T (I even was measuring and weighing my portion sizes)- the act of the matter was that my placenta was "eating" a ton of my insulin up... and as it grew, it ate more.
So here is the deal. When I had my baby she was 6lbs 5oz - about 2 weeks before my due date. She was perfectly healthy and her blood sugar was fine. My diabetes went away after pregnancy.
Now here is the kicker- So if you do well controlling your diabetes as well as you can... you have a healthy baby, are proclaimed diabetes-free, and you are free to go about your life right? NO- well only if you want to do this all next time you have a baby, and then ten years after if you become a type 2 diabetic! AFTER you have the baby it is wise to make sure you follow all their advice for helping prevent diabetes in the future. If you have pounds to lose, lose them (that diabetes diet works well for losing weight too... if you just change the portions) If you need to get fit - GET FIT! Do the work, and trust me, you'll be glad you did. See I was told that I would probably have diabetes right from conception if I ever got pregnant again, but 2 years later, 25 lbs thinner starting weight, and a LOT healthier, I was able to carry baby #2 with no gestational diabetes, or other complications for that matter. My doctors were very pleased and told me that they are 100% sure that my work after pregnancy prevented me getting gestational diabetes, and now that I have lost my baby weight again and continue to live as healthily as I can, I have drastically improved my odds of not being a diabetic in 10 years.
I know the word "diabetes" is terrifying... I cried on my way home from that appointment... But this can be a jumping off point for you! Take care of yourself and take care of your baby. If you are having a rough time make sure to TALK to your doctor and dietician. it is their job to help you find solutions, and give you ideas!
Good Luck!
