Gut Microbiota and Extraintestinal Disorders: Are They Interrelated?
Summary
This review examines how disturbances to the gut microbiome — the community of bacteria living in the digestive tract — are linked not just to intestinal diseases but also to allergies, asthma, and cardiovascular conditions. This context is relevant to microplastics research because ingested plastic particles have been shown to alter gut microbial communities.
ABSTRACT Normally in health, the commensal gut microbiota lives in a perfectly symbiotic relationship with the host. Initial bacterial colonization occurs through the maternal vaginal/fecal flora and oral feeding. When this symbiotic relationship is lost due to several factors, the condition is known as “dysbiosis.” Dysbiosis is associated with the pathogenesis of intestinal disorders, such as inflammatory bowel disease, irritable bowel syndrome (IBS), and coeliac disease, but recent studies have shown that it has also been implicated in extraintestinal disorders, such as allergy, asthma, cardiovascular disease, obesity, autoimmune diseases, inflammatory diseases, and some mental disorders and cancers. The proposed mechanism for the development of such disorders is disruption of the pivotal mutual relationship between the gut microbiome, the metabolic products produced by them, and the host immune response. In this review article, we would like to highlight the role of gut microbiota in the development of extraintestinal diseases. How to cite this article: Chandra A, Ray AK, Chakraborty U, et al .

Microplastics and human health: unveiling the gut microbiome disruption and chronic disease risks
This review summarizes evidence that microplastics disrupt the gut microbiome, the community of bacteria in our digestive system that plays a key role in immunity, metabolism, and overall health. By altering gut bacteria balance and triggering inflammation, microplastic exposure may contribute to chronic conditions including inflammatory bowel disease, metabolic disorders, and potentially even neurological problems through the gut-brain connection.
Microplastics and their interactions with microbiota
This review examines how microplastics interact with microbiota (the communities of microorganisms in the environment and in living bodies). Microplastics can carry harmful bacteria and disrupt the natural balance of microbial communities in soil, water, and the human gut. The disruption of gut microbiota by microplastics is particularly concerning because a healthy gut microbiome is essential for immune function, digestion, and overall health.
Toxicological Evaluation of Effects of Some Environmental Pollutants on Intestinal Microbiota: Traditional Review
This review examines how various environmental pollutants affect the gut microbiome — the community of microorganisms in the intestinal tract. Microplastics are among the pollutants discussed, and their ability to alter gut microbiota composition is increasingly recognized as a mechanism by which plastic particles may harm human and animal health.
Microplastics and the gut microbiome: Emerging health concerns and strategies
This review covers how microplastic ingestion affects the gut microbiome, describing mechanisms by which microplastics cause intestinal disorders, disrupt endocrine function, and promote pathogenic bacterial growth, while also noting inhalation and dermal absorption as secondary exposure routes.
Gut microbiota, a key to understanding the knowledge gaps on micro-nanoplastics-related biological effects and biodegradation
This review explores how micro- and nanoplastics affect the community of microorganisms living in the gut, and how those same gut microbes might be able to break down plastic particles. Swallowed microplastics can disrupt the balance of gut bacteria, potentially leading to various diseases. On the other hand, some gut bacteria can actually degrade plastics into smaller, less harmful molecules, opening a possible avenue for biological cleanup.
