Gestational Diabetes

Gestational diabetes, Type 3, also involves a combination of inadequate insulin secretion and responsiveness, resembling type 2 diabetes in several respects. It develops during pregnancy and may improve or disappear after delivery. Even though it may be transient, gestational diabetes may damage the health of the fetus or mother, and about 20%–50% of women with gestational diabetes develop type 2 diabetes later in life.

Gestational diabetes occurs in about 2%–5% of all pregnancies. It is temporary, and fully treatable, but, if untreated, may cause problems with the pregnancy, including macrosomia (high birth weight) of the child. It requires careful medical supervision during the pregnancy.

Because gestational diabetes can hurt you and your baby, you need to start treatment quickly. Treatment for gestational diabetes aims to keep blood glucose levels equal to those of pregnant women who don't have gestational diabetes. Treatment for gestational diabetes always includes special meal plans and scheduled physical activity. It may also include daily blood glucose testing and insulin injections. You will need help from your doctor, nurse educator, and other members of your health care team so that your treatment for gestational diabetes can be changed as needed.

For you as the mother-to-be, treatment for gestational diabetes helps lower the risk of a cesarean section birth that very large babies may require. Sticking with your treatment for gestational diabetes will give you a healthy pregnancy and birth, and may help your baby avoid future poor health.
