Gestational Diabetes and Obesity: Immediate and Late Sequelae for Offspring.

Background/

Objectives

Gestational diabetes mellitus (GDM) and maternal obesity are major global health gestation-related conditions associated with several adverse maternal and neonatal outcomes. GDM is a common gestational metabolic disorder, presented usually during the second or third trimester of pregnancy with maternal hyperglycemia due to insulin intolerance. Maternal obesity, defined as a BMI of a woman during gestation ≥ 30 kg/m2, has been associated with maternal complications such as GDM, fetal macrosomia and others.

Methods

The presented article is a narrative review. The aim of this study was to review scientific evidence and conduct a comprehensive analysis of GDM and maternal obesity ("diabesity") and its immediate and late complications for both maternal and fetal/offspring wellbeing.

Results

This review highlighted that gestational hyperglycemia results in oxidative and nitrogen stress development and that maternal obesity may have an impact similar to maternal diabetes, as it may cause fetal macrosomia and cardiometabolic complications later in life.

Conclusions

Optimal diabetic control is responsible for the prevention of oxidative stress in diabetic pregnancies. Similarly, pregnant women should exercise regularly, receive folic acid supplementation and avoid excess weight gain during pregnancy. Breastfeeding during the first months of life has a positive impact on weight monitoring in infants born to mothers with diabesity and may be crucial in the prevention of obesity and metabolic syndrome later in life.
