Women who are obese when diagnosed with gestational diabetes mellitus (diabetes associated with pregnancy) and who subsequently gain more weight are at higher risk for developing Type 2 diabetes, according to a new study published by the journal Diabetologia.
Researchers followed women with a body mass index (BMI) of 30 or more for 18 years after their gestational diabetes diagnosis. They found that the risk for developing Type 2 diabetes went up with every 2.2 pounds of additional weight gain. For each 11-pound weight increase, the risk increased by 27%.
The results of this study are not surprising. A high BMI causes an increase in insulin resistance. Insulin resistance is an underlying abnormality of both gestational and Type 2 diabetes.
Reducing the Risk
It is crucial for women with a history of gestational diabetes to maintain healthy weight and activity levels. Research has proven that those with a high BMI who lose 5 to 7% of their body weight and exercise 150 minutes a week significantly reduce the risk of developing Type 2 diabetes.
Starting a family can motivate some women who have struggled with extra weight and sedentary lifestyles. Establishing healthy habits can have a positive impact on children and family lifestyles.
Breastfeeding plays an important role, too. Nursing is associated with weight loss for the mother, plus a reduced risk of developing Type 2 diabetes for both mom and her baby. Breastfed babies have a reduced risk of childhood obesity as well. Nursing decreases children’s insulin resistance, among many other long-term benefits. Women who are most successful at breastfeeding received education while they are pregnant.
