What is a risk factor for developing gestational diabetes during pregnancy?

Obesity is a well-established risk factor for developing gestational diabetes during pregnancy. Excess body weight can lead to insulin resistance, which impairs the body's ability to use insulin effectively. This resistance increases the risk of elevated blood glucose levels during pregnancy, potentially resulting in gestational diabetes. The presence of excess fat, particularly in the abdomen, is particularly linked to metabolic changes that can contribute to the development of this condition.

In contrast, taking prenatal vitamins does not influence the risk of gestational diabetes, as they are intended to ensure that a pregnant person receives essential nutrients for the health of both the mother and the fetus. Being under the age of 25 generally does not correlate with an increased risk of gestational diabetes; in fact, younger mothers tend to have lower risk profiles. Lastly, regular physical activity is associated with a reduced risk of gestational diabetes, as it helps to maintain a healthy weight and improve insulin sensitivity.
