In the context of type 2 diabetes mellitus (T2DM), the concept of organ-specific insulin resistance (IR) as a localized manifestation has garnered increasing attention. A scoping review was conducted to investigate the clinical relevance of IR confined to individual organs without systemic metabolic implications. Utilizing a methodological framework adapted from Arksey and O'Malley, a comprehensive search of PubMed was performed, focusing on the period between January 1990 and October 2024. The search strategy combined Medical Subject Headings terms and keywords related to IR and specific organs. Notably, while insulin resistance yielded a substantial number of results, the subset of organ-specific insulin resistance returned a more limited dataset, highlighting a gap in current literature. The systematic selection process encompassed identification, screening, eligibility, and inclusion stages to ensure robust inclusion criteria. This scoping review underscores the importance of exploring organ-specific IR in the diabetic milieu and sets the stage for further research to elucidate its role in the pathogenesis of T2DM. Conclusion: The findings suggest that investigating organ-specific IR in the context of T2DM is a promising avenue for future research to deepen our understanding of disease pathophysiology. Thus, this scoping review answers the following question In Situ Resistance Insulin - Localized Type 2 Diabetes Mellitus or Type 6 Diabetes Mellitus?, emphasizing the need for targeted investigations into localized manifestations of IR and their implications for DM management strategies. Keywords: Insulinresistance, Organ-specific insulin resistance, Diabetes mellitus, Scoping review.
