Diabetes complicates about 8 percent of pregnancies each year. About 75 percent of these diabetic pregnancies are gestational diabetes—that is, the woman is diagnosed as having diabetes during the pregnancy. Of the remaining, 23 percent involve preexisting type 2 diabetes and about 1 to 2 percent involves preexisting type 1 diabetes.
The issues surrounding preexisting diabetes are slightly different from those faced by women who first develop diabetes during pregnancy. Women who have diabetes before they become pregnant have to deal with glucose control at conception and early in pregnancy. If there are any diabetes-related complications, these may also have an impact on the pregnancy. Women who have gestational diabetes are faced with learning all about diabetes, including watching their diet and taking insulin, while pregnant. This chapter gives you details on both situations.
