I got diagnosed with GD yesterday & my doctor wants me to test my blood 2 hours after every meal & fasting. My doctor wants me at 120 or less for meals, & 65-95 for fasting. So far my numbers have been 87 fasting, 107, 100, and I just ate dinner. I'm just curious how many carbs you can have for snacks & meals. It is not listed on the paper my OB gave me so I have no idea. My meals have been at 20 carbs today. I am having snacks in between as well usually around 5-10 carbs w/ protein as well. I got super lightheaded before dinner so am I doing this wrong? 🤔
