Glucose and lipid metabolism with triphasic oral contraceptives in women with history of gestational diabetes.Contraception. 1987 Mar; 35(3):257-69.C
The glucose and lipid metabolism in a group of women with previous history of gestational diabetes were evaluated before and after 6 months treatment with a low-dose triphasic oral contraceptives pill (TP). This group was compared with a control group of women, also with history of gestational diabetes, using intrauterine devices (IUD). In the TP group, 26.7% of the women developed impaired glucose tolerance which reverted to normal in all but one after cessation of the TP. The IUD group showed no change in glucose tolerance. The integrated insulin response to a 75g OGTT in the TP group increased by 48.3% at 6 months compared with an increase of 23.4% for the same period in the IUD group. In the TP group there was a significant decrease in serum total cholesterol without changes in HDL-cholesterol and triglycerides level. We conclude that even low-dose triphasic oral contraceptive pills can cause glucose intolerance in women with previous gestational diabetes mellitus.
