How long do I have to fast for?

I have my glucose tolerance test in the morning and my doctor didn't tell me exactly how long I had to fast for and I just cannot remember from when I did it with my first child.

  • um I'm not sure how those work exactly because I was already diabetic. but i would think you'd have to fast at LEAST 2 hours if not more to get an accurate blood sugar reading.

  • When I was pregnant with my son, I had to do a 12 hour fast. So when I scheduled the appointment, I made it as early as possible, then I ate a good meal @ dinnertime. Good luck, Sweetie!!

  • If it's the one where you drink a bottle of orange or grape "pop", then there's no need to fast. I'd call your doc/ob/hospital and find out for sure so you don't proceed wrong.

  • my doctor told me to eat like I normally did b/c the test would be more accurate that way. But he did tell me not to eat a pop-tart or a dozen donuts, lol. you should call your doctor and ask just to make sure so you don't have to drink the horrible "Drink" again.
