[Gestational diabetes mellitus : prelude of risks not to be misunderstood].

Gestational diabetes mellitus is a common complication in pregnant women. It is diagnosed between the 24th and 28th last menstrual period thanks to an oral glucose tolerance test with 75 g of glucose. Although blood glucose levels usually return to normal after childbirth, it can lead to some medium- and long-term complications, including cardiovascular, metabolic and renal complications. Early detection of various risk factors related to these complications would avoid some negative consequences for women with background of gestational diabetes.
