Study Notes
Definition of Diabetes Mellitus in Pregestational and Gestational Contexts
-
Pregestational Diabetes Mellitus (DM): Chronic metabolic disorder existing prior to pregnancy, primarily affecting carbohydrate metabolism.
-
Characterized by hyperglycemia, which results from:
- Limited insulin release in response to carbohydrate intake.
- Impaired cellular response to insulin.
-
May also disrupt fat and protein metabolic processes.
-
Gestational Diabetes Mellitus (GDM): Diabetes first identified during pregnancy.
Etiological Risk Factors for Gestational Diabetes Mellitus
-
Personal Characteristics:
- Age: Increased risk for individuals aged 35 years or older, particularly with a family history (FH) of diabetes.
- Family History: Significant risk if one has an identical twin with diabetes.
- Obesity: Body weight exceeding 110% of ideal body weight or BMI greater than 30 kg/m² increases risk, especially with parental diabetes history.
-
Obstetric Conditions:
- Grand Multiparity: Having five or more deliveries.
- Previous Gestational Diabetes: History of impaired glucose tolerance or GDM in earlier pregnancies is a strong risk factor.
- Macrosomic Delivery: Having delivered a baby weighing 4 kg or more previously.
- Repeated Abortions: History of multiple pregnancy losses.
- Excessive Gestational Weight Gain: Risk increases with significant weight gain during pregnancy.
- Glycosuria: Presence of glucose in urine noted during the first antenatal visit.
-
Others:
- Unexplained Intrauterine Fetal Death (IUFD) and perinatal loss.
- Birth of a baby with Congenital Malformations of Unknown Cause (CFMF).
- Unexplained polyhydramnios (excess amniotic fluid).
