Women who had gestational diabetes must have their glycemia closely checked after delivery to insure complete normalization. Few studies are published but breast feeding does not seem to modify the metabolic profile of the mother or the children. Contraception must take account associated risk factors. Very few studies are published and none notified a significant modification of the carbohydrate metabolism with hormonal contraception, either estroprogestative or progestative only. But associated obesity, hypertension or dyslipidemia need the prescription of a contraception with no vascular secondary effect. In these cases an intrauterine device represents a very good choice.
