People with risk factors for type 2 diabetes have a varying risk of developing type 2 diabetes as well as complications. Researchers from the Institute of Diabetes Research and Metabolic Diseases of Helmholtz Munich at the Eberhard Karls University of Tübingen, the University Hospital of Tübingen, the German Center for Diabetes Research (DZD), as well as the Universities of Lille and Rome investigated the extent to which the different subtypes benefit from bariatric surgery. The results show that the novel classification of diabetes risk subtypes can help to identify people who benefit particularly greatly from bariatric surgery. This can be an important step towards precision medicine.
