Maternal obesity significantly increases risks during pregnancy, including miscarriage, pre-eclampsia, and adverse fetal outcomes. Pre-conception weight loss is recommended for overweight and obese women.

Area of Science:

  • Reproductive health
  • Maternal-fetal medicine
  • Metabolic disorders

Background:

  • Overweight and obesity are prevalent in UK women of reproductive age, affecting 32% and 21% respectively.
  • Obesity profoundly alters maternal intermediary metabolism, with insulin resistance playing a central role.
  • These metabolic changes may contribute to increased fetal energy accumulation.

Purpose of the Study:

  • To review the impact of maternal obesity on pregnancy outcomes.
  • To highlight associated maternal and fetal risks.
  • To provide recommendations for managing maternal obesity in the context of pregnancy.

Main Methods:

  • Literature review and data synthesis on maternal obesity and pregnancy.
  • Analysis of risks including miscarriage, operative delivery, pre-eclampsia, thromboembolism, perinatal mortality, and macrosomia.

  • Examination of long-term risks of childhood obesity.

    • Main Results:

    • Maternal obesity is linked to a three-fold increased risk of miscarriage.
    • Obese women face higher rates of operative delivery, pre-eclampsia, and thromboembolism.
    • Fetal risks include increased perinatal mortality and macrosomia (large-for-gestational-age infants).

    Conclusions:

    • Maternal obesity poses significant risks to both mother and fetus.
    • Weight loss prior to pregnancy is advisable, but weight management during pregnancy requires careful consideration.
    • Evidence for managing maternal obesity is limited, necessitating practical, evidence-informed suggestions.
