Gestational diabetes mellitus (GDM) is a condition of significant risk to both mother and baby. GDM is associated with outcomes such as large babies, preeclampsia (a serious condition in pregnancy with high blood pressure and protein in the urine), stillbirth, low blood sugars in the baby after birth, and even future risk of the offspring developing obesity and cardiovascular disease. The prevalence of GDM is increasing over time. However, there is controversy on the best method of detecting this condition during pregnancy. This study is designed to compare two groups of patients: patients who have HgbA1c<5.7% and those between 5.7-6.4% (HgbA1c is a type of hemoglobin, the oxygen carrying molecule in the blood. A greater percentage of this type of Hemoglobin is associated with diabetes). Maternal and Neonatal outcomes will be compared in these groups as well as historical GDM and birth outcomes at LBMMC.
