Suspected Microplastic-like Particles in Human Gastric Autopsy Samples: An Exploratory Histopathological and Biochemical Study
AI summary Read the abstract
Scientists examined stomach tissue samples from 55 autopsies and found tiny plastic-like particles in about 1 out of 4 cases. Every person with these particles also had stomach inflammation, compared to only about a third of those without particles, suggesting a possible link between microplastics and digestive tissue damage. That said, this is a small, exploratory study, so more research is needed before we know if microplastics actually cause this inflammation or are just present alongside it.
Background: Human exposure to microplastics (MPs) is an emerging public health concern, yet their presence and pathological significance in gastric tissues remain poorly understood. This study investigated suspected MP-like particles in human gastric autopsy specimens, examining their association with histopathological changes and routine biochemical parameters. Methods: A retrospective post-mortem study was conducted on gastric tissue samples from 55 adults who underwent autopsies between 2022 and 2025. Tissue samples were digested using a hydrogen peroxide method, vacuum-filtered, stained with Nile Red, and quantified via ImageJ. Histopathological evaluation using hematoxylin–eosin staining and polarized light microscopy identified tissue-embedded suspected MP-like particles and assessed inflammation, necrosis, and fibrosis. Data were analyzed based on suspected MP-like particle detection status. Results: Suspected gastric MP-like particles were detected in 15 of 55 cases (27.3%). Most positive cases exhibited a low particle burden (median 1/g). Polarized light microscopy additionally served as a technical assessment tool, revealing birefringent structures measuring 26–84 μm within the gastric mucosa or lumen. All suspected MP-like particle-positive cases showed gastric inflammation compared to 35.0% of suspected MP-like particle-negative cases. Fibrosis and necrosis occurred exclusively in the suspected MP-like particle-positive group but lacked statistical significance. No significant associations were found between suspected MP-like particle detection and demographics, comorbidities, or systemic biochemical markers. Conclusions: Suspected gastric MP-like particles were identified in over a quarter of autopsy tissues and were strongly associated with localized gastric inflammation.

Higher abundance of micro- and nanoplastics in inflammatory tissues from patients with intestinal erosion
AI summary Read the abstract
Scientists studying gut tissue from patients with intestinal damage found nearly three times more microplastic particles in inflamed, injured tissue compared to healthy tissue nearby. While this small study (just six people) can't prove that microplastics cause gut inflammation, it's an early clue that these tiny plastic particles—found in our food, water, and packaging—might be linked to digestive health problems, making it a topic worth watching as research continues.

Researchers found nearly three times more microplastic particles in inflamed, damaged intestinal tissue compared to healthy tissue from the same patients, suggesting a possible link between plastic buildup in our gut and inflammation. This was a small study of just six people, so it can't prove plastics cause the inflammation—but it raises early questions about whether the microplastics we ingest from food, water, and packaging could be contributing to digestive health problems.
Microplastic in Gastric Fasting Liquid and Associated Gastric Pathology
AI summary Read the abstract
This study found microplastic particles in gastric fluid samples collected from patients undergoing routine stomach examinations, and noted associations between microplastic presence and gastric pathologies including H. pylori infection, intestinal metaplasia, and inflammation. The findings provide direct clinical evidence that microplastics accumulate in the human stomach and may be linked to gastric disease, though causality is not yet established. This is an important step toward understanding whether microplastic ingestion contributes to gastrointestinal health problems in humans.

Researchers examined tissue samples from patients who had colon surgery and detected microplastics in the specimens. The findings suggest that microplastics are commonly present in the human colon, adding to a growing body of evidence that these particles accumulate in the human digestive system.
Screening for Suspected Microplastic-like Particles in Post-Mortem Human Liver: Correlating Histopathological Alterations with Clinical Profiles
AI summary Read the abstract
Scientists examined liver tissue from 55 deceased adults and found tiny suspected microplastic particles in about 1 in 6 samples. Livers with these particles were more likely to show signs of scarring (fibrosis) and inflammation, though blood tests didn't clearly flag these changes, suggesting standard checkups might miss plastic-related liver damage. This is early evidence from real human tissue (not just animal studies), but larger studies are needed before we know how worried to be.
