BOSTON, November 15, 2023 — Women with metabolic syndrome during pregnancy may be delivering more than just a baby—they’re also potentially impacting the very structure of the placenta, according to a new study. Researchers found significant differences in placental gross morphology between pregnant women with and without the condition, raising questions about long-term implications for both mother and child.
Placental Changes Linked to Maternal Metabolic Health

A comparative study reveals structural differences in placentas of women with metabolic syndrome.
- Maternal metabolic syndrome—a cluster of conditions including high blood pressure, high blood sugar, unhealthy cholesterol levels, and abdominal fat—is increasingly common during pregnancy.
- The study, conducted between January 2021 and December 2022, compared placental structures from 70 women with metabolic syndrome to 70 without.
- Researchers observed statistically significant differences in placental weight, length, width, and thickness between the two groups.
- These structural changes could potentially affect placental function, impacting fetal growth and development.
What exactly does this mean for expecting mothers? The study highlights a potential link between a mother’s metabolic health and the physical development of the placenta, a vital organ for fetal nourishment and waste removal. Researchers suggest these changes could have implications for pregnancy outcomes.
The Study Details
The research team, working with participants at a single hospital, meticulously examined placentas after term pregnancies (between 37 and 40 weeks gestation). They measured placental dimensions—length, width, and thickness—and recorded the overall weight. Women were diagnosed with metabolic syndrome based on established criteria, including elevated fasting glucose levels, blood pressure readings, and waist circumference.
Statistical analysis revealed significant differences in all measured parameters. Placentas from women with metabolic syndrome were, on average, smaller in all dimensions compared to those from women without the condition. These findings suggest a systemic impact of metabolic syndrome on placental development.
Why Does This Matter?
The placenta isn’t just a passive intermediary; it actively regulates nutrient and oxygen transfer to the fetus. Alterations in its structure could compromise these vital functions. “These structural changes may affect placental efficiency, potentially leading to fetal growth restriction or other adverse pregnancy outcomes,” explained researchers. Further investigation is needed to fully understand the functional consequences of these observed differences.
Looking Ahead
While this study establishes a correlation, it doesn’t prove causation. Future research should focus on the functional implications of these structural changes and explore potential interventions to mitigate the effects of maternal metabolic syndrome on placental development. Understanding these mechanisms could lead to improved strategies for managing pregnancies complicated by metabolic disorders.
Q: What is metabolic syndrome?
A: Metabolic syndrome is a cluster of conditions—high blood pressure, high blood sugar, unhealthy cholesterol levels, and excess abdominal fat—that increase your risk of heart disease, stroke, and type 2 diabetes. It’s becoming increasingly prevalent in pregnant women.
