The prevalence of obesity is rising worldwide dramatically, affecting up to 50 percent of the population. The epidemic of obesity leads to a marked increase in the metabolic syndrome, a cluster of cardiovascular risk factors characterized by visceral obesity, insulin resistance, low HDL-Cholesterol, hypertriglyceridemia, and a subclinical proinflammatory state. In the last years, the NCEP and the WHO highlighted and defined the key features of the metabolic syndrome to facilitate the clinical diagnosis and preventive interventions. The conservative therapy of obesity and the metabolic syndrome by life style intervention and pharmacological interventions leads only to moderate weight loss with inconstant long-term success. Intervention by bariatric surgery can serve as a model for the metabolic effects of permanent weight loss. In several studies the pronounced weight loss induced a reduction of almost all components of the metabolic syndrome, including glucose and lipid status and is followed by an improvement in the quality of life. Recent research suggested a decrease in mortality rate in addition to cost effectiveness of bariatric surgery.
