Gestational Diabetes Mellitus

Detection All pregnant women should be screened for glucose intolerance because selective screening based on clinical attributes or past obstetric history has been shown to be inadequate. Pregnant women who have not been identified as having glucose intolerance before the 24th wk should have a screening glucose load between the 24th and 28th wk consisting of 50 g of oral glucose given without regard to time of the last meal or time of day. Venous plasma glucose is measured 1 h later. A value of >7.8 mM (>140 mg/dl) is recommended as a threshold to indicate the need for a full diagnostic glucose tolerance test.
