Bariatric surgery has become increasingly more common for the treatment of morbid obesity. It is effective for reduction in overall body weight and also has beneficial effects on glucose levels and improvements in insulin resistance. The mechanisms for these improvements are not completely understood, but hypothesized to be due to a combination of post-operative reduction of caloric intake and changes in the entero-insular axis or incretin system. Other, less desirable, metabolic effects of bariatric surgery include a high incidence of nutritional deficiencies which include calcium, vitamin D, B vitamin, iron, and zinc deficiency. Hypoglycemia has also been reported in a minority of cases. All of these metabolic effects will be discussed in detail in this chapter.
