Disorders of Pregnancy
In the course of its research on healthy pregnancy, the NICHD has made great progress in understanding features of disorders that may occur during pregnancy. Work is ongoing to find ways to treat and prevent these disorders to help women have healthy pregnancies and healthy babies.
Gestational Diabetes Mellitus
Researchers estimate that GDM occurs in nearly 7 percent of all pregnancies. Unlike some other disorders that occur during pregnancy, GDM is often treatable. GDM treatment plans should be designed by a health care provider to address a woman's specific health needs. In general, many GDM treatment plans include: following a healthy meal plan as outlined by a health care provider; getting regular, moderate physical activity; maintaining a healthy weight gain; and measuring and recording blood sugar levels. Some women also need to take insulin or other medications to maintain a healthy pregnancy.
Even though it usually goes away after the baby is born, GDM can affect the health of both mother and baby later in life. For instance, women who have GDM during pregnancy have a 40 percent greater chance of developing type 2 diabetes later in life. And, babies born to mothers with GDM are at greater risk than babies born to other mothers of developing type 2 diabetes or being obese (extremely overweight) later in life.
Because babies born to mothers with GDM tend to be larger than average, GDM can also affect the way a baby is delivered. In some cases, the safest way to deliver a baby from a mother with GDM is by surgery, called cesarean section; but, cesarean section delivery carries its own risks.
The NICHD supports a great deal of research on GDM, its risk factors, and its treatments. One study, supported by the NICHD through the Maternal-Fetal Medicine Unit (MFMU) Network, is examining the benefits of counseling and dietary management in treating mild GDM. Other clinical trials on GDM are also underway.
The NICHD offers Are you at risk for gestational diabetes? a brochure that outlines the risk factors for GDM and summarizes recommendations from American College of Obstetricians and Gynecologists about testing for GDM. In addition, Managing Gestational Diabetes: Your Guide to a Healthy Pregnancy provides general information and guidelines for keeping yourself healthy if you have GDM.
Preeclampsia and Eclampsia
Eclampsia (ee-KLAMP-see-uh) is a more severe form of preeclampsia that can lead to seizures and coma. Estimates place the number of women affected by eclampsia at one in 200 women who have preeclampsia. Eclampsia can be fatal if it's not treated quickly.
High blood pressure is one possible sign of preeclampsia. Having abnormal levels of protein in the urine is also part of preeclampsia. If you are pregnant and your blood pressure normally runs high, or is suddenly high, your health care provider may ask for frequent urine samples throughout your pregnancy, to test your urine for protein as a sign of preeclampsia.
