The Forum reviewed key factors contributing to the development and progression of type 1 diabetes and outlined specific, high-priority research questions. Knowledge gaps were identified, and, notably, opportunities to harness disease heterogeneity to develop personalized therapies were outlined. Herein, we summarize our discussions and review the heterogeneity of genetic risk and immunologic and metabolic phenotypes that influence and characterize type 1 diabetes progression (presented as a palette of risk factors). We discuss how these age-related factors determine disease aggressiveness (along gradients) and describe how variable immunogenetic pathways aggregate (into networks) to affect β-cell and other pancreatic pathologies to cause clinical disease at different ages and with variable severity (described as disease-related thresholds). Heterogeneity of pathogenesis and clinical severity opens avenues to prevention and intervention, including the potential of disease-modifying immunotherapy and islet cell replacement. We conclude with a call for 1) continued research to identify more factors contributing to the disease, both overall and in specific subgroups; 2) investigations focusing on both individuals who surpass metabolic and immune thresholds and develop diabetes and those who remain disease free with the same level of immunogenetic risk; and 3) efforts to identify where the current type 1 diabetes staging system may fall short and determine how it can be improved to capture and leverage heterogeneity in prevention and intervention strategies.</p><p><p></p>","PeriodicalId":93979,"journal":{"name":"Diabetes care","volume":" ","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144746617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective obesity treatment may lead to T2D remission and can greatly improve dysglycemia and insulin sensitivity. The main objective of this article is to describe the growing evidence in support of targeting obesity to treat T2D in youth. There is growing evidence and guidance that for adults with T2D medical and surgical treatments for obesity should be prioritized. Yet, for youth with T2D, there has been limited movement to prioritize treating obesity, despite its role in diabetes pathophysiology. In adults, addition of obesity medications and bariatric surgery to the diabetes treatment regimen results in substantial weight reduction, improvement in dysglycemia, and decreased use of diabetes agents. In youth, there is limited, yet mounting evidence of these same benefits. U.S. Food and Drug Administration-approved obesity medications are effective and well tolerated in youth with obesity and an important therapeutic tool for youth with T2D and obesity. For several medications clinically significant weight reduction has been demonstrated, with improvement in insulin resistance and dysglycemia. In youth with T2D significant weight reduction has been demonstrated with bariatric surgery, with significant 3- and 10-year diabetes remission rates.
