Microplastic and nanoplastic exposure and risk of diabetes mellitus

The issue of plastic pollutants has become a growing concern. Both microplastics (MPs) (particle size < 5 mm) and nanoplastics (NPs) (particle size < 1 µm) can cause DNA damage, cytotoxicity, and oxidative stress in various organisms. The primary known impacts of microplastic/nanoplastic are observed in the liver and respiratory system, leading to hepatotoxicity and chronic obstructive pulmonary disease. Although research on the effects of MPs and NPs on diabetes is still in its early stages, there are potential concerns. This editorial highlights the risk to diabetics from co-exposure to contaminants and MPs/NPs, supported by evidence from animal studies and the various chemical compositions of MPs/NPs.
