Abstract

Background: Gestational diabetes mellitus (GDM) is a condition characterized by hyperglycemia that is first diagnosed during pregnancy. It increases both fetal and maternal risk and is related to future metabolic abnormalities in women and their offspring. Therefore, appropriate diagnosis and management of GDM are crucial.
Current Concepts: There are two strategies to diagnose GDM?a one-step strategy comprising a 75 g oral glucose tolerance test (OGTT), and a two-step strategy involving a 50 g OGTT followed by a 100 g OGTT.
The former can detect more glucose abnormality during pregnancy; however, either method is acceptable, considering the evidence regarding pregnancy outcomes. The mainstay of glucose management in GDM is medical nutrition therapy with appropriate physical activity and self-monitoring of glucose. Insulin therapy is required if hyperglycemia cannot be controlled by lifestyle interventions. Generally, insulin therapy is immediately discontinued after childbirth, and 75 g OGTT is recommended at 4 to 12 weeks in the postpartum period and every 1 to 3 years thereafter. Lifestyle intervention is important in women with a history of GDM to prevent future diabetes.
Discussion and Conclusion: GDM prevalence is increasing because of higher maternal age and prevalent obesity. Healthcare providers and women of childbearing age need to be more careful with regard to the detection and management of GDM, and treatment strategies should be personalized.
