Gestational diabetes mellitus (GDM) is analyzed by raised blood glucose in pregnancy however the definition has changed over and again since its first portrayal in the 1960's . The most much of the time announced perinatal result of GDM is macrosomia (generally characterized as a neonate weighing over 4 kg) which can build the danger of cesarean segment and shoulder dystocia. For the mother, there are likewise potential longer-term results including an expanded danger of type 2 diabetes post-pregnancy or potentially in later life [3]. The examiners of an enormous worldwide Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study expected to distinguish a slice point in the continuum to choose the blood glucose level (BGL) limits that ought to be utilized to characterize GDM [4]. Be that as it may, a conclusive cut-point was not distinguished and utilizing the HAPO information the International Association of the Diabetes and Pregnancy Study Groups (IADSPG) accord board suggested a BGL edge related with the danger of unfriendly newborn child results, (for example, danger of macrosomia, abundance baby adiposity and neonatal hyperinsulinemia). This change was disputable, and there is at present an absence of a concurred standard for diagnosing high blood glucose in pregnancy.
