@Stephen Why do you say there’s a 50% chance of your kids getting it? I’ve always know the risks are higher if your father has diabetes than your mother, but have never heard of it being that high. I’ve read the figures below from numerous sources over the years – this particular quote is taken from the American Diabetes Association because it was the first I came across:
“In general, if you are a man with type 1 diabetes, the odds of your child getting diabetes are 1 in 17. If you are a woman with type 1 diabetes and your child was born before you were 25, your child’s risk is 1 in 25; if your child was born after you turned 25, your child’s risk is 1 in 100.
Your child’s risk is doubled if you developed diabetes before age 11. If both you and your partner have type 1 diabetes, the risk is between 1 in 10 and 1 in 4.”

I think ShootUp readers have previously resolved the T2 issue by voting to cull Type 2’s to cut costs (sorry @Teloz
