Role of gut microbiota in the pathogenesis of metabolic syndrome: an updated comprehensive review from mechanisms to clinical implications.

Modern studies have linked gut microbiota to metabolic syndrome - a condition linked to obesity, characterized by insulin resistance, dyslipidemia, hyperglycemia, and hyperlipidemia. The gut microbiota, influenced by diet, plays a pivotal role in metabolic syndrome, affecting energy absorption, metabolism, and immune responses. Dysbiosis disrupts energy metabolism and immune responses contributing to metabolic endotoxemia, leading to insulin resistance and systemic inflammation. Key metabolites like short-chain fatty acids and bile acids, modulate insulin sensitivity and metabolic pathways. Therapeutic strategies involving probiotics and prebiotics show potential in managing diabetes and cardiovascular diseases by targeting lipid metabolism, inflammation, and atherosclerosis. However, challenges in therapy standardization and regulatory approval remain. Continued research on gut microbiota's role in metabolic syndrome could lead to innovative, personalized treatment and prevention strategies based on individual metabolic profiles. The review aims to elucidate the underlying mechanisms that influence metabolic health and cardiovascular function. It seeks to synthesize current research findings, highlighting the role of microbial composition, diversity, and metabolic byproducts in the modulation of host metabolism and cardiovascular outcomes.
