Cure8 research brief
Environmental pollutants that are increasing in many East Asian settings — air pollution, heavy metals, pesticides, and microplastics — may contribute to rising IBD rates by affecting the gut microbiome and intestinal barrier. Recognizing these exposures could point toward prevention or mitigation opportunities.
Researchers studying IBD causes (especially environmental and microbiome research), clinicians interested in population-level IBD risk factors, public health professionals, and patients or advocates concerned about environmental contributors to IBD in East Asia.
This review summarizes evidence linking environmental pollutants (air pollution from vehicle and industrial emissions, heavy metals and pesticides in water and food, and pervasive microplastics) to rising IBD rates in East Asia.
The authors describe proposed mechanisms including changes to the gut microbiome and disruption of the intestinal barrier that could promote intestinal inflammation.
The paper focuses on exposures common in rapidly industrializing East Asian settings and highlights motor vehicle and industrial emissions, contaminated drinking water, seafood and produce, and microplastics as important sources.
The review emphasizes that understanding these environmental contributors may help identify modifiable risk factors and inform prevention or mitigation strategies. Because this is a narrative review with limited region-specific primary data, it summarizes existing studies and mechanistic hypotheses rather than reporting new trial results or causal proof.
It is useful for clinicians, researchers, and patients interested in environmental and lifestyle drivers of IBD trends. Keep the review’s regional and evidence limitations in mind: data specific to East Asia are described as limited, and mechanistic links are largely based on associative studies and laboratory work rather than definitive human causal trials.
This article is a narrative review (abstract-level source content provided). The authors note limited region-specific primary data; mechanistic pathways are plausible but not proved as causal in humans. Interpret findings as a synthesis of existing studies and hypotheses rather than new clinical trial evidence.

If environmental microplastics contribute to gut dysbiosis and mucosal inflammation, this could help explain environmental triggers of ulcerative colitis and point toward prevention or microbiome-targeted interventions.
Malassezia extracellular vesicles can modulate immune and microbial interactions; if similar mechanisms affect the gut, they could be relevant to inflammatory bowel disease and Crohn’s disease, though current evidence is...
FUT2 connects genetics, mucosal sugars, and the gut microbiome — pathways that could help explain why some people with IBD have different microbiomes or disease risk. If validated in trials, FUT2-targeted or...
