The definition of gestational diabetes was until recently
one of the few things that did not generate more discussion, understanding
as any degree of glucose intolerance with onset
or first recognition during pregnancy, regardless of the type
requiring treatment, and the persistence of the condition or not
after pregnancy (122). With the new proposal from the International
Association of Diabetes and Pregnancy Study Groups (IADPSG) (127) is set
new terminology differentiates gestational diabetes
itself of overt diabetes (preexisting diabetes
but hitherto unrecognized) concepts we will need
later.
For over 45 years, O'Sullivan and Mahan (123) established
the criteria for the interpretation of oral tolerance test to
glucose in pregnancy for the diagnosis of gestational diabetes, criteria
that with the changes made 28 years ago by Carpenter
and Coustan (124), remained in use until the end of 2010, being
the hitherto accepted by the American Diabetes Association
(ADA) (125). We should note that the establishment of such criteria
based on the risk of developing diabetes after pregnancy, and not
in identifying women at increased risk of outcomes
adverse perinatal.
