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.

Autoimmunity that leads to type 1 diabetes or celiac disease or thyroid autoimmunity affects 1 in 20 children and adolescents in the U.S. While treatments are available, prevention of these common autoimmune diseases has been elusive due to poor understanding of the environmental causes and their interactions with common predisposing or protective genetic variants. In 2002, the NIDDK established The Environmental Determinants of Diabetes in the Young (TEDDY) consortium to advance understanding of the causes and the natural history of type 1 diabetes and other autoimmune diseases.
