I have cold hands. I have noticed that as my BG levels decrease so does the temperature of my hands (starts at the tips of my fingers and travels up my fingers/hands.arms)
Yeh it's defo to do with being diabetic as I'm type one for about 1 half yeas and my hands and feet are always cold and they used to be fine before being a diabetic
I too have cold hands and feet. Funny thing is I wasnt aware of it before changing my diet. I now wear merino mix socks and have two reusable magic gel hand warmers.
