This definition is critical as it helps healthcare providers differentiate gestational diabetes from other forms of diabetes, such as preexisting type 1 or type 2 diabetes, which are not induced by pregnancy. Gestational diabetes usually resolves after delivery, although it may increase the risk of developing type 2 diabetes later in life for both the mother and the child.

The other options do not accurately reflect the definition or nature of gestational diabetes. For instance, glucose intolerance post-delivery refers to a different situation where women may still have high blood sugar after giving birth, which does not fit the definition of gestational diabetes. The inability to produce insulin during pregnancy describes a condition more akin to type 1 diabetes, rather than the insulin resistance encountered in gestational diabetes.
