What is gestational diabetes?
According to The WHO (World Health Organization) definition, gestational diabetes, also “Pregnancy diabetes “, is a carbohydrate tolerance disorder leading to a variable severity hyperglycemia, beginner or diagnosed for the first times during pregnancy.

Thus, as with other diabetes, gestational diabetes is a disorder of blood glucose control (sugar levels) resulting in an excess of glycemic in the blood (chronic hyperglycemia).

Gestational diabetes occurs in pregnant women near the end of the second trimester. It can be quite asymptomatic and thus go unnoticed or present symptoms similar to those of other types of diabetes: intense thirst, frequent and abundant urine, heavy fatigue, small discomfort, etc.

Gestational diabetes can last only the time of pregnancy and then disappear or be indicative of previously unknown diabetes. In all cases, gestational diabetes must be closely monitored and treated as it poses a risk to both the mother and the child.

At-risk situations
Pregnancy is a risk in itself of diabetes because the hormonal changes that the pregnant woman undergoes induce a physiological state of insulin resistance that can worsen as the pregnancy progresses.

Screening is done on a simple blood test, in the laboratory of medical tests, usually between 24th and 28th week of Amenorrhea in all pregnant women at risk. A first blood glucose test is performed on an empty stomach, followed by a OGTT (oral hyperglycemia) test that corresponds to the swallowing of 75 g of glucose in one intake. A single value above normal thresholds (0, 92g/L on an empty stomach; or 1, 80g/L 1h after oral glucose; or 1, 53g/L 2h after) is sufficient to detect gestational diabetes.

Since 2010, in France, Diabetologists and Gynecologists have agreed on the criteria for people at risk of gestational diabetes:

  • Late pregnancy: Among women over 35 years of age, prevalence reaches 14.2%
  • Body mass index (BMI > 25kg/m²): In overweight or obese women, prevalence is 11.1% and 19.1%, respectively.
  • A personal history of gestational diabetes: for women who have already developed gestational diabetes in a previous pregnancy, prevalence rises to 50%
  • A family history of type 2 diabetes (parents, brother, sister)
  • A history of fetal macrosomia: birth weight of a baby greater than 4 kg
