Analysis of Microplastics in Human Feces Reveals a Correlation between Fecal Microplastics and Inflammatory Bowel Disease Status
AI summary Read the abstract
Researchers analyzed microplastics in the stool of patients with inflammatory bowel disease (IBD) and healthy volunteers, finding that IBD patients had significantly higher concentrations of microplastics in their feces. PET plastic and polyamide were the most common types found, likely originating from food packaging and dust. The positive correlation between microplastic levels and IBD severity suggests that microplastic exposure may be linked to gut inflammation, though it is not yet clear whether the plastics contribute to the disease or the disease causes more plastic retention.
Human ingestion of microplastics (MPs) is inevitable due to the ubiquity of MPs in various foods and drinking water. Whether the ingestion of MPs poses a substantial risk to human health is far from understood. Here, by analyzing the characteristics of MPs in the feces of patients with inflammatory bowel disease (IBD) and healthy people, for the first time, we found that the fecal MP concentration in IBD patients (41.8 items/g dm) was significantly higher than that in healthy people (28.0 items/g dm). In total, 15 types of MPs were detected in feces, with poly(ethylene terephthalate) (22.3-34.0%) and polyamide (8.9-12.4%) being dominant, and their primary shapes were sheets and fibers, respectively. We present evidence indicating that a positive correlation exists between the concentration of fecal MPs and the severity of IBD. Combining a questionnaire survey and the characteristics of fecal MPs, we conclude that the plastic packaging of drinking water and food and dust exposure are important sources of human exposure to MPs. Furthermore, the positive correlation between fecal MPs and IBD status suggests that MP exposure may be related to the disease process or that IBD exacerbates the retention of MPs. The relative mechanisms deserve further studies. Our results also highlight that fecal MPs are useful for assessing human MP exposure and potential health risks.

Researchers found higher concentrations and greater diversity of microplastics in fecal samples from inflammatory bowel disease patients compared to healthy controls, suggesting a potential association between microplastic ingestion and gut inflammation, though causality remains to be established.
Microplastics and Inflammatory Bowel Disease: From Environmental Exposure to Clinical Uncertainty
AI summary Read the abstract
This review paper summarizes existing lab and human research on tiny plastic particles and inflammatory bowel disease (IBD). Lab studies suggest these particles may disrupt the gut's protective lining and worsen inflammation, while human studies found associations between plastic levels and IBD symptoms, but do not prove plastics cause the disease.
Exposure to polyethylene microplastics exacerbate inflammatory bowel disease tightly associated with intestinal gut microflora
AI summary Read the abstract
This study found that polyethylene microplastics, one of the most common types found in everyday products, worsened inflammatory bowel disease symptoms by disrupting the gut microbiome. The microplastics changed the balance of gut bacteria in ways that increased intestinal inflammation. These findings suggest that swallowing microplastics through food and drinks could make existing bowel conditions worse or contribute to gut inflammation in otherwise healthy people.
Micro- and Nanoplastics: A Paradigm Shift in the Pathogenesis of Inflammatory Bowel Disease
AI summary Read the abstract
This review paper summarizes research showing that tiny plastic particles from food and water may contribute to inflammatory bowel disease (IBD), a painful condition affecting the digestive system. Early studies suggest these microscopic plastics can damage the gut lining and trigger inflammation, though more research is needed to prove they directly cause IBD. Since plastic exposure can potentially be reduced, understanding this connection could lead to new ways to prevent or treat digestive diseases.
Effects of microplastics in aquatic environments on inflammatory bowel disease
AI summary Read the abstract
Researchers reviewed current evidence on how microplastics found in aquatic environments may contribute to the occurrence and progression of inflammatory bowel disease (IBD). The study's analysis of in vitro and in vivo research suggests that prolonged exposure to microplastics through contaminated aquatic foods and drinking water may pose risks to intestinal health, though the relationship between microplastic exposure and IBD requires further investigation.
