Introduction: Diabetes Mellitus, Type 2 is a common disease in modern societies and one which has attracted the attention of researchers.  An examination of the literature that has contributed to the formation and growth of this field helps us to explore its thematic structure, and identify the main focus of research papers.

Methods: This is an applied research study which uses Scientometrics approaches. Research materials include documents related to the treatment of Diabetes Mellitus, Type 2 in PubMed for the period 2005 to 2014. Data analysis has been carried out using descriptive-analytical statistics and social network analysis techniques. To prepare a matrix of mesh descriptors, a software package called Ravar Matrix has been used, while for the purpose of social network analysis the Ucinet software package and its supplementary package, Netdraw, has been implemented.  

Results: The results demonstrate the growth of scientific production in this field in the years 2005 and 2013. 57 countries were involved in writing the papers, with the United States, England, Germany, Ireland and the Netherlands at the top of the list respectively. According to the Closeness and Betweeness Centrality Indicators of terms on the maps, the most active research areas in the field are as follows: Drug Therapy, Vascular Diseases, Blood, and Chemistry changes, Metabolism, Physiology, Pathophysiology and Diagnosis.

Conclusion: Results of co-word analysis revealed outstanding topics of the field under study, which is useful for policy makers to learn about the research status and make appropriate decisions for the promotion of scholarly products.
