I can see why your under type1 care.
Best to be safe than sorry.
Ive never been tested for type1 but the insulin just to be enough for my now 17+stones is huge in comparison.
I was getting to 22-23st.
I was tested when first pregnant for weight loss whilst not on insulin and my bgs were in 20s and odd 30. That child is overweight. Second pregnancy was metformin and insulin and in 7s with odd 9s. Son not IR. However levothyroxine wasn't working well hense this child has special needs.
