How do you get Diabetes, besides eating too much sugar?

It's usually hereditary. Undigested and unused sugar content in us is passed into our blood system which could cause excessive sugar that could bring on diabetes later. Besides cutting down on sugary foods, certain fruits should also be eaten moderately like bananas, (for us Asians would include durians because they have very high sugar contents), rice and noodles.
Pregnant mothers are always advised to cut down on sweet foods because they're most prone to diabetes. So, I guess that's where the family line of diabetes starts for it to be hereditary.

Diabetes is caused when the pancreas either produces too much (A), or too little (B) sugar. It can be caused by abusing sugar and items containing sugar, being overweight, genetics, and/or unhealthy habits.
My Doctor says that they still don't really know the cause for sure. There is some evidence to support the theory that it runs in families, although the fact that a family member has it does NOT guarantee that you will too. But they have also NOT concluded that eating too much sugar causes it.
lots of reading, discussions with physicians, dietitians, etc. Type I for almost three years now.
Where in the world did you get THAT bit of misinformation... you don't get Diabetes from eating sugar... you get Diabetes from BEING FAT.
you are born with it
Eating too much sugar does NOT give you diabetes!!!!

It is a condition that causes your body to be unable to use the sugar from food as energy like it's supposed to. Heredity plays a part, and being overweight tends to make it more likely. Beyond that--nobody really knows!

And other than hellyeah up above me, they are all wrong wrong wrong!!
