Growing evidence suggests that daily, perpetual exposure to chemicals may be secretly increasing the risk of gestational diabetes, according to a major new scientific review.
Researchers have found that pregnant women with high exposure to per- and polyfluoroalkyl substances, known as PFAS, are more likely to develop gestational diabetes and see changes in the way their bodies regulate insulin.
This finding comes from the most comprehensive systematic review and meta-analysis to date examining lifetime PFAS exposure and diabetes-related outcomes.
The study brings new clarity to a field that has produced mixed results and highlights that pregnancy is a particularly vulnerable time.
Sandra India Aldana, co-lead author of the study from the Icahn School of Medicine at Mount Sinai, explained: “This is the most comprehensive evidence synthesis to date examining how PFAS exposure is associated not only with diabetes risk but also with underlying clinical markers that precede the disease.”
“Our findings suggest that pregnancy is a particularly sensitive period during which exposure to PFAS may increase the risk of gestational diabetes.”
PFAS dangers
PFAS are a large group of synthetic chemicals that have been used in consumer and industrial products for decades.
These are commonly found in food packaging, nonstick cookware, water- and stain-resistant fabrics, and firefighting foam. Its chemical structure makes it extremely difficult to break down, earning it the nickname “eternal chemical.”
PFAS persist in the environment and accumulate in the human body over time, so nearly everyone experiences some level of exposure.
Scientists are increasingly linking these substances to health problems ranging from immune dysfunction to hormonal disorders, calling for more detailed research into their role in metabolic diseases.
Stronger evidence on the risk of gestational diabetes
A new review analyzed data from numerous population studies to assess whether PFAS exposure is associated with diabetes and related metabolic markers.
The most consistent and convincing evidence has emerged regarding gestational diabetes, which is characterized by high blood sugar levels during pregnancy.
Studies have shown that the higher the exposure to PFAS, the more likely you are to develop gestational diabetes.
In addition, those with higher exposure showed changes in insulin resistance and insulin secretion, two important biological processes involved in blood sugar control. These findings suggest that PFAS may interfere with the normal metabolic adaptations that occur during pregnancy.
Although gestational diabetes was strongly associated with PFAS exposure, the evidence regarding type 1 and type 2 diabetes in the general population remained inconclusive. The researchers say this does not prove that the association does not exist, but rather reflects a gap in existing research.
Why gestational diabetes is worth your attention
Gestational diabetes affects millions of pregnancies worldwide and can lead to serious complications if not managed properly.
Short-term risks include high birth weight, preeclampsia, and the need for a Caesarean section. In the long term, both mother and child face an increased risk of developing type 2 diabetes later in life.
This new finding is particularly concerning because exposure to PFAS is so widespread and often unavoidable. Given how common both PFAS exposure and pregnancy are, even a small increase in the risk of gestational diabetes could have significant public health implications.
Implications for healthcare and prevention
This review suggests that environmental exposures may deserve more attention in reproductive and prenatal care.
Understanding the potential for patient contact with PFAS through drinking water, food, or consumer products can be part of a more comprehensive approach to gestational diabetes risk assessment.
For those planning a pregnancy or already pregnant, reducing exposure to PFAS as much as possible may be a prudent precaution.
This includes paying attention to food packaging, avoiding overly processed fabrics, and staying informed about local water quality. Although exposure cannot be completely eliminated through individual actions, awareness is an important first step.
Next steps in PFAS research
The researchers emphasize that larger, long-term studies are needed to understand how PFAS affect diabetes risk over time.
Future research will aim to investigate how environmental exposures interact with genetics and how PFAS contribute to related diseases such as obesity and chronic liver disease.
For now, this evidence strengthens the concern that environmental chemicals play a role in gestational diabetes and emphasizes the need to consider chemical exposure as part of maternal health.
As scientists continue to unravel the link between PFAS and metabolic disease, the discovery adds urgency to discussions about environmental regulation, public health protection, and safer alternatives to persistent chemicals.
