This brochure addresses the problem of gestational diabetes and answers the most frequently asked questions about the disease. It begins by defining gestational diabetes and discussing its cause, then addresses such topics as: (1) how gestational diabetes differs from other types of diabetes; (2) who is at risk for developing gestational diabetes and how it is detected; (3) how gestational diabetes affects pregnancy and whether it will hurt the baby; (4) what can be done to reduce problems associated with gestational diabetes; and (5) how to monitor blood glucose levels. Other topics concerning the disease involve health of the baby, labor and delivery, weight gain during pregnancy, breast-feeding, insulin, diet, and exercise. Figures in the brochure show how the pancreas produces insulin, how high maternal glucose affects the fetus, the distribution of weight gain during pregnancy, and the six food groups. Seven tables show values for a three-hour glucose tolerance test for gestational diabetes, a prenatal weight gain grid, prepregnancy weight limits, protein equivalents, a daily food guide, caffeine comparisons, and calorie comparisons. Also included are a sample menu for 2,000 calories, a glossary of terms, and forms for self-monitoring of blood glucose and food and exercise. (SH)
