The Role of Chronic Microplastic Exposure in the Pathogenesis of Non-Communicable Diseases: A Narrative review
AI summary Read the abstract
This review summarizes existing research on how long-term exposure to tiny plastic particles, called microplastics, may relate to diseases like heart disease, diabetes, cancer, and lung conditions. Studies in cells and animals suggest possible links through inflammation and other biological changes, but the review states direct cause-and-effect in humans is not yet proven.
Abstract Background: Presence of microplastic in the environment causes chronic microplastic exposure to human through ingestion, inhalation and dermal contact. This chronic microplastic exposure lead to various non-communicable disease. Despite widespread environment prevalence of microplastic, the health risks associated with microplastic exposure are still uncertain. Microplastics, defined as plastic particles smaller than 5 mm in diameter, have become ubiquitous environmental contaminants due to the exponential growth in plastic production and inadequate waste management. Human exposure to microplastics occurs through ingestion, inhalation, and dermal contact, resulting in their accumulation in various tissues and organs. Emerging evidence suggests that chronic microplastic exposure may contribute to the development of noncommunicable diseases (NCDs) through multiple biological mechanisms. Objective: To review current evidence regarding the role of chronic microplastic exposure in the pathogenesis of major non-communicable diseases, including cardiovascular disease, diabetes mellitus, cancer, and chronic respiratory diseases. Methodology: A narrative review of published literatures was conducted to examine the relationship between chronic microplastic exposure and non-communicable disease development. Evidence from epidemiological, experimental, in vitro, and animal studies was reviewed to evaluate the biological pathways linking microplastic exposure to disease pathogenesis. Key mechanisms including oxidative stress, chronic inflammation, immune dysregulation, gut microbiota alteration, and cellular dysfunction were analyzed. Result: Available evidence indicates that chronic microplastic exposure may contribute to the development and progression of NCDs through multiple interconnected mechanisms. Microplastics have been associated with vascular inflammation and atherosclerotic plaque formation, increased oxidative stress, disruption of glucose homeostasis, alterations in gut microbiota, and activation of oncogenic signaling pathways. Experimental studies have demonstrated that microplastic uptake by immune cells can induce pro-inflammatory responses and cellular damage, potentially increasing susceptibility to cardiovascular disease, diabetes, cancer, and chronic lung disease. Conclusion: Although direct causal relationships in humans remain incompletely established, current evidence suggests that chronic microplastic exposure represents a potential emerging environmental risk factor for non-communicable diseases. Further longitudinal and mechanistic studies are required to clarify long-term health consequences and inform public health policies aimed at reducing human exposure to microplastics.

The potential of micro- and nanoplastics to exacerbate the health impacts and global burden of non-communicable diseases
AI summary Read the abstract
This review presents evidence that micro- and nanoplastics may worsen non-communicable diseases like heart disease, diabetes, and respiratory illness by fueling chronic inflammation in the body. The authors also propose that people already suffering from these diseases may absorb even more microplastics due to their weakened tissue barriers, creating a harmful feedback loop.
Environmental Exposure to Micro- and Nanoplastics: Linking Cardiovascular Disease and Cancer Through Shared Biological Pathways—A Critical Review
AI summary Read the abstract
Tiny plastic particles from our air, food, and water are showing up inside the human body, and this review pulls together existing research suggesting they may trigger inflammation, cell damage, and other harmful processes linked to both heart disease and cancer. The catch: most of this evidence comes from lab and animal studies so far, not large human studies, so scientists can't yet say for certain that microplastics cause these diseases in people. Still, given how common plastic exposure is in daily life, this is a strong signal that more research—and possibly more caution—is warranted.
Micro- and Nanoplastics as Emerging Cardiovascular Stressors: Mechanisms of Vascular Injury, Atherothrombosis, and Myocardial Dysfunction
AI summary Read the abstract
This review summarizes research on tiny plastic particles found in human blood, arteries, plaques and heart tissue. Studies suggest these particles may damage blood vessel linings and trigger inflammation linked to heart disease, but the paper notes current human evidence cannot prove plastics actually cause these conditions.
Environmental Exposure to Micro- and Nanoplastics: Linking Cardiovascular Disease and Cancer Through Shared Biological Pathways

Tiny plastic particles from our environment—found in air, food, and water—may get into our bodies and trigger inflammation and cell damage linked to both heart disease and cancer, according to this review of existing research. While the studies so far are mostly from labs and animals rather than large human trials, the findings suggest these plastics could be a hidden contributor to two of the world's biggest killers. More research on real-world exposure and long-term effects in people is still needed before we know for sure how much risk they pose.
Microplastic and Nanoplastic Exposure and Cardiovascular Disease: A Narrative Review of Mechanistic Evidence, Candidate Epigenetic Pathways and Current Evidence Gaps
AI summary Read the abstract
This review paper summarizes existing research on whether microplastics and nanoplastics affect heart and blood vessel health. Studies in cells, mice and fish found signs of oxidative stress, inflammation and altered DNA activity after plastic particle exposure, and one human study linked plastics found in neck artery plaque to higher rates of heart attack, stroke or death. The authors conclude a clear biological pathway remains unproven.
