About

Walter J. Pories is a pioneering figure in metabolic and bariatric surgery, best known for his transformative contributions to the understanding and treatment of obesity and type 2 diabetes. His research has fundamentally reshaped how the medical community views bariatric procedures, particularly gastric bypass, as a means not only for weight loss but also for the remission of metabolic diseases. Among his most impactful work is the landmark study demonstrating that gastric bypass surgery leads to rapid, durable resolution of type 2 diabetes, a finding that has been cited over 2,000 times and has driven a paradigm shift in diabetes management. Pories’s investigations into the perioperative safety of laparoscopic versus robotic gastric bypass, including a propensity-matched analysis of early experience (68 citations), have helped refine surgical techniques and improve patient outcomes. His career, spanning decades, has earned him numerous accolades, including the American Society for Metabolic and Bariatric Surgery’s highest honor. With over 300 peer-reviewed publications and a citation count exceeding 20,000, Pories remains a foundational voice in the field, inspiring a generation of surgeons and researchers to explore surgery’s role in treating chronic disease.
