Prospective parents may be fearful of transmitting diabetes to their children. The risk of transmitting type 1 diabetes is quite low (6 percent if the father has type 1 diabetes and 3 percent if the mother has type 1 diabetes). The risk of transmitting the genetic risk is higher in type 2 diabetes: if the mother has type 2 diabetes, the risk is about 18 percent, increasing to 50 percent if both parents have type 2 diabetes. The environment, however, plays a bigger role in the development of type 2 diabetes, regardless of the genetic risk.
