Social mixing most sport, Soaps!
I went into hospital for eye surgery three days ago, and am a Type 2 diabetic with good control.
Just prior to going into Theatre my BG levels were checked by the nurse and it was 4.8.
I had fasted from 6pm the previous day and this was taken at 2pm by the nurse.
However when I arrived back home at 7pm that evening my level had gone to 14.3
Now I did have two ginger biscuits and a cup of tea upon coming round in hospital so expected a small rise but I've never ever had a reading above 11
Does anyone know if this is what anaesthetic does, or could it be stress to my body with the operation?
 
The biscuits would gave had a fair bit to do with it. Have you tested biscuits before, especially on a empty stomach?
 
When I had a surgery 2 years ago, the doctor told me before that if needed she will inject glucose during the surgery, because I was afraid that I will go low as I was not allowed to eat either.
Maybe this has happened in your case as well since you had 4.8 prior to your surgery.
But it may be other factors as well, as stress, tiredness, eating on an empty stomach or other medication that was given to you.
 
I spiked massively whilst under a general anaethestic in March, to the extent that they have to put me on a sliding scale of insulin during the surgery. they said it can happen and part of it is the bodies stress response. Took a few days for my BG to get back to normal levels.

I don't eat biscuits at all, but was encouraged to have two small ginger ones with a cup of tea after coming round. I do feel it's more to do with the anaesthetic since my diet is almost carb free these days but who knows?

Thank you for sharing this @Nicki70 and although I'm Type 2 I do still wonder why they were taking my blood sugar readings right up to the operation.

The stress (the bodies response to stress) may have played a part too.
