Gestational Diabetes - immediately put on metformin and insulin without opportunity to try diet control?

[acaciabluebell]

I had my GTT last week and results were quite high: 6.5 fasting and after drink was 12.7 which I know is very high. I met with consultant yesterday who said I immediately have to start on Metformin 2x day, insulin 4x day including the fast acting and long acting one before bed. I haven't even been given the option to try diet control at all! So yesterday I started testing my glucose and readings have been:

1 hour after lunch: 5.2
Just before dinner: 4.1
1 hour after dinner: 5.4

Fasting this morning: 5.1

I feel like these numbers are fine and this is without any medication, just diet control. I don't mind the Metformin I am just wary to start insulin 4x a day if its not needed as it can cause hypos/low blood sugar. What would you do in my situation? I have bags and bags of insulin sitting in my fridge and I feel apprehensive to start it.

Or is it likely my machine is broken (it was brand new??)

Just wanted to update this thread and say that I managed to control my GDM with diet and exercise and did not need the truckload of medication I was prescribed. Still have a fridge full of insulin which was never touched 🤣
