Gestational Diabetes During Pregnancy Symptoms can complicate pregnancy. According to the American Diabetes Association, almost 10 percent of pregnant women who did not have diabetes before pregnancy will be diagnosed with gestational diabetes. Gestational diabetes occurs when a woman’s body can’t make enough insulin during pregnancy to compensate for her natural hormonal changes. Gestational diabetes is manageable, especially if diagnosed in time and properly treated. The more you know, the better prepared you can be. Keep in mind that you're not alone.
