With the notable increases at a global scale of the prevalence of obesity, a huge number of alternatives for its treatment have been developed. The surgical interventions have demonstrated to be effective in obtaining a significant and sustained weight loss. Complications have been described after the surgical procedures, which include those derived directly from surgery, nutritional abnormalities like malnutrition and deficiencies in micro and macro nutrients, metabolic abnormalities such as modifications in the calcium metabolism, formation of gallbladder stones and also some rare entities like nesidioblastosis; these adverse effects frequently affect the quality of life including vomit and Dumping syndrome, and the adaptive upheaval related to the need of modifying eating habits. Mortality is directly related to the surgeons expertise, and it has shown to be very low at places with important experience and an interdisciplinary group.
