The aim is to find the incidence of GDM using 75-g oral glucose tolerance test (OGTT) as a single-step screening and diagnosing GDM. Antenatal women attending Obstetrics department OP at Government Rajaji hospital, Madurai. Irrespective of age, parity and risk factors were subjected to a standardized 75 g oral glucose tolerance test (OGTT). Blood samples were obtained after 2 hours and venous plasma glucose was measured using an autoanalyser. 140mg/dl and above was taken as a cut off for GDM diagnosis. This study was conducted between July to december 2016. A total of 1,352 pregnant women were included in the study. Among the 1352 Ante natal women, GDM was diagnosed in 127 women. The incidence was found to be 9.39%. In this analysis, risk factors that are significantly associated with GDM were increasing age and increasing parity. Most of the cases were found positive between 24 to 28 weeks. As the percentage of pregnancies with GDM is increasing, a timely intervention is needed to prevent further complication associated with GDM. The cut off valve for diagnosing GDM can be decreased to 130mg % to increase the sensitivity of the test.
