A large genome-wide analysis reports that common obesity traits share, and in some cases drive, risk for diabetic kidney disease, diabetic retinopathy, and diabetic neuropathy. The study maps shared DNA signals, tests causal links, and points to pathways that could support earlier screening and treatment across organs. The findings are published in the journal Biomolecules and Biomedicine.
