Global Research Hotspots and Trends in Obesity-Related Venous Thromboembolism (2000-2025): a Bibliometric Analysis.

INTRODUCTION

Obesity is closely associated with venous thromboembolism (VTE), yet no studies have thoroughly investigated this specific area or identified potential future research trends. This study aims to address this issue.

METHODS

We searched the Web of Science Core Collection(WoSCC) and Scopus databases for articles on obesity and VTE published between 2000 and 2025. We then used VOSviewer, citeSpace, and the bibliometrix R package to analyze and visualise publication origins, collaboration networks, citations, co-citations, and keywords, research trends.

RESULTS

Since 2000, the number of papers and citations in this field has increased yearly. The United States ranks first in academic influence. The most influential institutions are the Mayo Clinic, Harvard Medical School, and Cleveland Clinic. The journals with the greatest impact are "Obesity Surgery," "Surgery for Obesity and Related Diseases," and "Thrombosis and Haemostasis." Keyword analysis emphasises the importance of themes such as "bariatric surgery" and "complications", as well as "risk factors" and "Covid-19".

CONCLUSION

This study systematically summarizes obesity-related VTE research and identifies global hotspots and trends. These findings highlight the collaborative models, research focuses, and emerging research areas commonly found in the existing literature, and can serve as a useful reference to inform future research directions and hypothesis development in this field.
