I can totally relate. 100%. I was diagnosed at 28 weeks, I am also thin, exercise, watch my diet... except I have no family history and I am 25. I was devastated, cried for days, etc. I still struggle with it sometimes, because there's all the info out there that says I am 50% more likely to develop type 2 now and my daughter is more likely to be obese as a child and develop type 2.
Well, I am here to tell you, these statistics aren't true for some women. My dietician really helped me see that. Yes, if after these pregnancies we never exercised and ate bad diets, we would get type 2. BUT PRETTY MUCH ANYONE WOULD!!!! If we feed our children crap and don't encourage them to be active, yup, they might develop type 2 or be overweight. I don't know about you, but I plan to maintain a healthy lifestyle after this for the sake of my child & myself.
It's important to remember that even with a family history or age factors coming into play- YOU DID NOT CAUSE THIS TO HAPPEN! It's your placenta. Your hormones are messing with your ability to process insulin.
The other important thing to remember while eating meals is PROTEINNNN!! Eat a ton of protein. I have found meat protein works the best. That would be my guess as to why your number was high after the dinner with quinoa and black beans. I bet if you would have added some meat protein (it can be anything you want! Chicken! Steak! Salmon!) it would have been lower. I would also recommend that you add meat to your rice and veggie dinner even tho your number was good. Protein is important for you and your baby.
Did you eat a bedtime snack? If you don't eat a bedtime snack, your fasting number will almost always be high. That is because when you don't give your body something to break down overnight- it goes into survival mode and dumps glucose in your system thinking you're starving. What has worked best for me- 5 triscuit crackers, 1 string cheese and a piece of dark chocolate. I go to bed, fast for around 8 hours and 15 minutes and my fasting is between 70-86. Sometimes when it's 86, I notice I took longer to fall asleep, or I fell asleep stressing about something. Sleep & stress play a huge part in your blood sugar numbers as well. The one time I got a higher fasting number (92), I was extremely stressed out and slept terribly the night before.
I am going thru the same things as you- I get hungry! The problem with your breakfast is that there are no carbs. Please do not avoid carbs all together. Add some greek yogurt or a 100% whole wheat piece of toast with peanut butter, almond butter, low fat cream cheese, butter... whatever you like. I eat 1 egg, (sometimes I add peppers or onions), a chicken apple sausage, and a piece of whole wheat toast with PB and cinnamon. My number after is always in the 90s or lower. If you don't eat any carbs... that would be dangerous for your baby. GD is about finding what carbs work for you, and pairing them with lots of protein. Calcium is an important factor, eat cheese, yogurt, almond milk, etc. Even ice cream is okay! Just find one that works for you.
My OB has to constantly remind me to relax. My numbers hardly go over 100- the point isn't to have constantly low numbers... they are just to be in the range of whatever your dietician tells you. For me, its under 140 at one hour after eating and under 95 for fasting. It's hard to let go, because I am like you VERY worried about my baby but I can assure you I have been controlling this thru diet and exercise and she's measured on time every step of the way. We have our growth ultrasound next week and I am hoping for good results- of course I am nervous as all hell but... I have done everything I can do keep her healthy. If GD is managed well, IT IS NOT HIGH RISK! My doctor reminds me of that every time I am in her office. It sounds like you will have no problem controlling this. I hope you have a meeting with a dietician soon, after I met with her I felt so much better.
I am so sorry you got dealt this card too- it's not fun, but I can tell you everything is going to be okay.
