Rubino Francesco is a researcher at King's College London. Professor Rubino’s research showed that the anti-diabetes effect of certain bariatric procedures, particularly gastric bypass surgery, results from mechanisms beyond weight loss. This evidence provided a scientific rationale for surgical treatment of type 2 diabetes, including that of less obese patients. Professor Rubino’s research-finding and theories also point to a role of the gastrointestinal tract in the pathophysiology of diabetes and obesity. His clinical expertise includes laparoscopic, bariatric, metabolic and upper digestive surgery, including gastric bypass, sleeve gastrectomy, gastric banding and novel procedures. He is internationally recognized as one of the world’s leaders in the research, teaching and practice of metabolic and weight-loss surgery.
