Bad Breaks and Metabolic Effects of Bariatric Surgery

Although bariatric surgery techniques were originally developed to treat morbid obesity, the indications for their use have expanded as a consequence of the emerging evidence of their wider metabolic benefits.  Now described as metabolic surgeries, these treatment methods derive as much benefit from their metabolic and cardiovascular effects as from the resulting weight reduction. Though promising evidence is emerging, there is a need for further mechanistic studies to assess the true potential of metabolic surgery to treat the myriad other disorders of metabolism and to better understand their consequences in terms of cardiovascular disease and cancer risk reduction.  Additionally, there may be unintended consequences of bariatric surgery that are related to long term adverse skeletal effects and nutritional deficiencies.
