About
Amir S. Naderi, MD
Board-certified internist and nephrologist working at the intersection of kidney disease and obesity medicine — the editor of Nephrobesity.
Dr. Naderi is a board-certified Internist and Nephrologist and a Fellow of the American Society of Nephrology (FASN). His work centers on the obesity–nephrology interface — the cardio-renal-metabolic space where modern incretin pharmacology, chronic kidney disease, and metabolic risk converge. He completed his Internal Medicine residency at the University of Texas Southwestern Medical Center (2005–2008) and his Nephrology fellowship at The Johns Hopkins University Hospital (2008–2010), and holds board certification in Internal Medicine and Nephrology from the American Board of Internal Medicine (ABIM), with equivalent specialist recognition (Facharzt für Innere Medizin und Nephrologie) in Germany.
His interest in the kidney–obesity axis is long-standing. His doctoral thesis (2003) — an early German study — examined a fatty-acid-binding-protein (FABP2 Thr54) polymorphism in patients with morbid obesity. Across 335 patients (mean BMI 51.4 ± 7.8 kg/m²), the FABP2 Thr54 allele frequency was 26.8% (genotyped by PCR–restriction fragment length polymorphism [PCR-RFLP] with the restriction enzyme Cfo I), with no significant association with type 2 diabetes, the degree of obesity, or lipid disorders.
His clinical practice now integrates evidence-based obesity pharmacotherapy — GLP-1 receptor agonists, dual incretins, and emerging multi-agonist therapies — with the management of chronic kidney disease, hypertension, and cardiometabolic risk.
He is the founder and medical director of a physician-led internal medicine, nephrology, and obesity medicine practice in Hamburg, Germany, and has previously served as medical director of an outpatient dialysis unit. He is an appointed examiner for the specialist board examinations of the Hamburg Medical Association and a recipient of a Teaching Excellence Award for his clinical instruction.
Nephrobesity grew out of that clinical and academic work. It exists to give nephrologists, endocrinologists, and internists a source-bound reference for the evidence at the kidney–obesity intersection.
