Which of the following is a risk factor for gestational diabetes?

A family history of diabetes is considered a significant risk factor for gestational diabetes. This is because genetics can play a crucial role in the development of insulin resistance and glucose metabolism issues. If a family member, such as a parent or sibling, has a history of type 2 diabetes, it increases the likelihood that an individual may develop similar metabolic challenges during pregnancy, leading to gestational diabetes.

In the context of other factors, while high blood pressure can accompany gestational diabetes, it is not a direct risk factor for its development. Furthermore, excessive exercise is generally viewed as beneficial during pregnancy and does not increase the risk of gestational diabetes; in fact, it may help in managing weight and blood glucose levels. Lastly, a low carbohydrate diet, while it may influence overall health and weight management, is not recognized as a risk factor for gestational diabetes. In contrast, it can be part of a balanced nutritional approach for some individuals during pregnancy.
