Mounting research continues to reveal the pervasive presence of microplastics within the human body, and a new study highlights a concerning impact: damage to the pancreas. Scientists in Spain and Poland have discovered that even low doses of polyethylene terephthalate (PET) – a common plastic found in everyday items like water bottles – can disrupt pancreatic function, possibly contributing to rising rates of metabolic diseases. This research, conducted on pigs as a human analog, underscores the urgent need to understand the long-term health consequences of microplastic exposure and is prompting calls for greater preventative measures.

Microplastics, incredibly small plastic particles, are damaging the pancreas, new scientific research reveals. This damage could contribute to the rising rates of diabetes and obesity seen in recent decades. The study indicates that low doses of polyethylene terephthalate (PET)—commonly found in plastic bottles—have a toxic effect on the organ.
Researchers from Spain and Poland observed these harmful effects during experiments on pigs, an animal model physiologically similar to humans. For four weeks, pig pancreases were exposed to both low and high doses of PET, according to reporting from The Independent. The findings raise concerns about the potential impact of microplastic exposure on human health.
The research team found alarming evidence that PET microplastics can cause significant cell death in the pancreas and lead to severe disruptions in organ function. The particles directly impacted proteins involved in key pancreatic processes. “PET-microplastics affected the amount of proteins in a dose-dependent manner,” the study stated, “the low dose changed the amount of seven proteins, while the high dose changed seventeen.” Notably, researchers observed an abnormal increase in fat droplet accumulation within the pancreas after exposure to PET microplastics. Fat droplet buildup is linked to reduced insulin secretion and impaired glucose metabolism.
The PET particles also triggered inflammation in the pancreas. Researchers believe these results suggest similar effects could occur in humans and are urging policymakers to take the health risks of microplastics seriously. The study’s findings underscore the growing need for research into the long-term effects of microplastic exposure on human health and the environment.
