Question: How can I lower my chance of developing gestational diabetes?
Answer: If you are thinking about becoming pregnant and are overweight, you can lower your chance of developing gestational diabetes by losing extra weight and increasing physical activity before you become pregnant. Taking these steps can improve how your body uses insulin and help your blood glucose levels stay normal.

Once you are pregnant, don’t try to lose weight. You need to gain some weight for your baby to be healthy. However, gaining too much weight too quickly may increase your chance of developing gestational diabetes. Ask your doctor how much weight gain and physical activity during pregnancy are right for you.
