[Predisposition and phenotypes of gestational diabetes]

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Public Health

Context:

• Gestational diabetes (GDM) is a frequent pregnancy complication in industrialized nations, affecting approximately 4.3% of births in Germany.
• GDM is characterized by glucose intolerance diagnosed via oral glucose tolerance testing, with criteria recently adopted by the WHO.
• It signifies a precursor to type 2 diabetes, involving insulin resistance and impaired beta-cell function.

Purpose:

• To define Gestational Diabetes Mellitus (GDM) and outline its prevalence and diagnostic criteria.
• To explore the metabolic profile, genetic predispositions, and risk factors associated with GDM.
• To highlight the long-term health consequences for both mother and offspring, and to propose preventive measures.

Summary:

• GDM is a significant pregnancy complication with a high conversion rate to overt type 2 diabetes within 10 years.
• Risk factors include family history, previous GDM, metabolic syndrome, unhealthy lifestyle, advanced maternal age, and preconceptional obesity.
• GDM can lead to offspring obesity through fetal programming, emphasizing the importance of preventive strategies.

Impact:

• Understanding GDM's link to type 2 diabetes aids in early risk identification and management.
• Identifying GDM risk factors allows for targeted interventions to reduce maternal and offspring morbidity.
• Promoting GDM prevention through lifestyle modifications can mitigate long-term public health burdens associated with diabetes and obesity.
