Yes. Diabetes type 2 is a hereditary condition. The risk is greatest when there are several family members who have the disease, as well as when the kids are overweight, sedentary, and/or have other type 2 diabetes risk factors. If you have type 2 diabetes, your child has a 10-15% chance of developing the disease. Furthermore, there is a 75% chance that the other identical twin will also get type 2 diabetes if the first twin in the pair has it.
