Objective: This study employs a bibliometric approach using network analysis to understand the progress and trends in FD research. The findings aim to provide a basis and guidance for further in-depth studies on FD. Methods: Publications related to FD from 2014 to 2023 were retrieved from the Web of Science Core Collection, as of July 1, 2024. The bibliographic data were imported into VOSviewer, CiteSpace, and the bibliometrix package to extract relevant information. A bibliometric analysis was conducted on various factors, including the number of annual publications, number of authors, organizations, countries, journals in which the articles were published, citation frequency, and keywords. Results: A total of 2,134 publications were retrieved. Tack J ranked first with 109 publications, followed closely by Talley NJ with 105 publications. The top three institutions in terms of publication volume were Katholieke Universiteit Leuven in Belgium (n=131), the University of Newcastle in Australia (n=112), and the Mayo Clinic (n=61). The country with the most publications was China, with 1,638 papers. The top three journals by publication volume were Neurogastroenterology and Motility (n=211), Journal of Neurogastroenterology and Motility (n=84), and Digestive Diseases and Sciences (n=55). The three most cited publications were the Kyoto Global Consensus Report on Helicobacter pylori Gastritis, ACG Clinical Guideline: Treatment of Helicobacter pylori Infection, and Gastroduodenal Disorders. The top three most-used papers over the past 180 days were Dietary fiber (oligosaccharide and non-starch polysaccharide) in preventing and treating functional gastrointestinal disorders - Challenges and controversies: A review, Kyoto Global Consensus Report on Helicobacter pylori Gastritis, and Understanding neuroimmune interactions in disorders of gut-brain interaction: from functional to immune-mediated disorders. Co-occurrence analysis of keywords showed a close relationship between FD and irritable bowel syndrome, functional gastrointestinal disorders, gastroparesis, Helicobacter pylori, gastric emptying, abdominal pain, gastroesophageal reflux disease, anxiety, quality of life, and depression.
