OBJECTIVE To investigate the current research status and trends of gut microbiota in diabetes both domestically and internationally, thereby providing a reference for advancing related studies. METHODS By systematically retrieving literature on diabetes and gut microbiota published in the Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) databases from 2000 to 2024, visual analyses were performed using specialized tools to examine the number of publications, authors, institutions, journals, citation frequencies, and keywords. RESULTS A total of 1 514 Chinese and 2 780 English articles were retrieved. Since 2010, the number of published articles has shown an upward trend. Domestically and internationally, high-impact journals include the Chinese Journal of Microecology and Nutrients, respectively. High-frequency keywords revealed key areas such as metabolomics, insulin resistance, and bifidobacteria (Chinese), research hotspots including diabetic nephropathy, intestinal nitrogen homeostasis disorder, and probiotic supplementation (English). Future research will focus on specific strains, metabolites, and traditional Chinese medicine therapies. CONCLUSION Significant progress has been made in the study of gut microbiota and diabetes; however, disparities between domestic and international research remain. In the future, efforts should be directed toward deepening mechanistic research, enhancing interdisciplinary collaboration, and promoting clinical translation.
