| That's wierd - as far as I'm aware, there's a theory that says the reason T1 exists more in certain populations is because it used to act as a survival mechanism in the Ice Age. People with higher blood sugar levels were less likely to freeze than those with normal levels, and whilst obviously their condition would eventually kill them, it gave them time to reproduce more than their less sugary companions.
I'm not entirely sure that having cold extremities is really anything to do with diabetes. It happens to a lot of people, diabetic or not. I always used to have really cold hands when I was younger, and this was prior to me developing diabetes. My mother has, to put it midly, the cold, frigid hands of Satan, and she's not diabetic either.
To be honest with you, I'd say it's nothing to worry about, but if you're really that concerned then have a word with your doctor. Body temperature problems are sometimes a sign of thyroid disorders, which appear to be more common in individuals with diabetes.  |
