The effects of subsequent states of excess hormone exposure, for example, subsequent pregnancy, hormonal contraception, and hormonal replacement therapy, on the development of diabetes in women with prior gestational diabetes were assessed. Current literature examining the effect of parity, hormonal contraception, and hormonal replacement therapy in healthy women and women with previous gestational diabetes and current diabetes was reviewed. Subsequent pregnancy in women with prior GDM appears to triple the risk of subsequent diabetes. Low-dose progestin and estrogen combination oral contraceptives do not appear to clinically increase the risk of diabetes. Hormonal replacement therapy appears to provide the greatest reduction in coronary artery disease to women at greatest risk, i.e., those who have developed diabetes. Careful follow-up and metabolic surveillance should be provided when prescribing hormonal contraception or replacement therapy. In women with prior gestational diabetes, exposure to repeat pregnancy poses a greater risk for subsequent diabetes than does either an exposure to low-dose progestin and estrogen combination oral contraceptives or to postmenopausal hormonal therapy, both of which do not appear to increase the risk of diabetes.
