[Postprandial glycemic variations of pregnancy in diabetes].

Postprandial blood glucose peaks are essential to consider in the high-risk situation featured by pregnancy in diabetic women, through several aspects. First, from a diagnostic point of view, post-stimulative situation offers the optimal sensitivity and specificity for a proper gestational diabetes screening. Next, when considering foetomaternal complications, third term postprandial hyperglycemia is highly predictive of child birth weight. Last, regarding metabolic monitoring, taking postprandial blood glucose into account leads to increasing insulin dosage, improving final term HbA1c and, finally, a lower average birth weight. However, it is mandatory for a proper management to avoid borderline glycemia, as blood glucose peaks are useful for fetal growth.
