I know a lot of people with gd. They are mainly asian though. And they were young when they got it. Under 30. So I'm not sure if age is a factor.
Omg 12 hours fasting. I think I'll struggle. And I hate sweet drinks. Even lemonade now makes me sick. But before pregnancy, I don't have lots of sweet stuff. My fav is ice cream. I could go weeks or months without chocolates, biscuits, etc. I never put sugar in tea or coffee. I used to years ago then one day I decided not to and now hate sweet drinks.
