My mother had diabetes will i get diabetes?

What my doctor told me was that with my mother and grandmother both having diabetes that I had a 50% chance of getting it,when both parents have it then you have a nearly 100% chance of getting it.You can maybe keep from getting it if you eat a good diet,exercise and keep check on your blood sugar.The more over weight that you are the higher chance of getting diabetes.I am tp 2.Hope this has helped you.
