Abstract

Diabetes mellitus is a silent disease and in women mostly it is first diagnosed during pregnancy, during pre-conceptional care or as an investigation of infertility. The screening tests vary in each country, and the cut-off values vary for diagnosing GDM. A 75 gm GTT carried out during pregnancy usually at between 24-28 weeks is the widely accepted test with any one abnormal value as per IADPSG criteria. But by this gestational age many women with hyperglycaemia are missed as it is not advocated by many during the first trimester, the period of organogenesis and fetal damage is enevitable. Fasting hyperglycaemia as screening tool has been thought of during precenceptional or periconceptional periods.
