The relationship between abnormal glucose tolerance and hypertensive disorders of pregnancy in healthy nulliparous women

Insulin resistance may be a factor in hypertensive disorders of pregnancy. Gestational diabetes mellitus is associated with increased risk for preeclampsia or other hypertensive disorders during pregnancy, although not at a statistically significant level. Likelihood of preeclampsia also is positively correlated with the plasma glucose level one hour after a 50-g oral glucose challenge. Preeclampsia was not prevented by calcium supplementation.
