Title: A Randomized Clinical Trial of Treatment for Mild Gestational Diabetes Mellitus
Brief Summary: Gestational diabetes mellitus (GDM) is a type of diabetes (high blood sugar) that occurs in pregnant women. This study will determine whether treating pregnant women who have mild GDM improves the health of their babies. The follow-up study will examine whether factors during the previous pregnancy (such as blood sugar during pregnancy) are associated with the woman and her child's health 4-9 years later.
