I have GD too, I just stopped using sugar in anything.
Also only basmati rice and not too much of it, wholemeal bread not white or brown, no pasta and watch very carefully of my general carb in take I’ve cut potatoes out too substitute sweet potatoes instead.
You’re first appt you will most likely get a blood monitor and a diary to record your blood results. I have to take mine three times a day, before each meal one day and an hour after each meal the next.
I’ve also cut down my portions and try and go for walks or exercise after I’ve eaten to burn off excess sugar.
I also have additional growth scans but baby seems fine and is growing according to the normal curve (thankfully).
I’ve joined the Facebook group linked to the website pp linked to which has been great.
A friend sent me diabetic chocolates and biscuits which help when I get sugar cravings.
It’s an annoying condition but I’m so very greatful it’s only temporary (hopefully).
You’ll be fine, make a list of questions you might have for your consultant and also do take a look at the linked website.
