To systematically analyze the current status and research trends and identify the key research hotspots in the field of gut microbiota and metabolic syndrome (MetS) from 2005 to 2024, thus providing references for future research and intervention strategies. Relevant literature on gut microbiota and MetS was retrieved and screened from the Web of Science Core Collection. Bibliometric tools such as VOSviewer, CiteSpace, and the R package bibliometrix were used to analyze the publication trends, countries and institutions, research themes, and emerging hotspots. A total of 4 210 relevant publications were included. The annual number of publications showed an increasing trend, which was particular rapid after 2010. China and the United States led in publication output, and major research findings were published in journals such as Nutrients, Gut, and Nature. Research hotspots primarily covered the fields of nutrition and diet, biochemistry and molecular biology, and microbiology. Keyword evolution analysis revealed a shift from early descriptive studies on gut microbiota composition to mechanism investigations focusing on dysbiosis-related pathways such as energy metabolism, inflammatory responses, and gut-organ axes. Co-occurrence analysis further indicated that key microbial metabolites (e.g., short-chain fatty acids and bile acids) and microbiota-targeted interventions (e.g., probiotics and fecal microbiota transplantation) had become focal points in recent studies. This bibliometric study comprehensively summarizes the research landscape of gut microbiota and MetS and highlights emerging trends and directions. Given the limitations of conventional therapies in terms of targeting specificity, patient adherence, and long-term safety, microbiota-based interventions offer a promising breakthrough for the prevention and treatment of MetS, providing valuable theoretical support for future precision medicine.
