Among obese subjects, bariatric surgery is very effective to achieve weight loss, to improve metabolic disturbances such as diabetes mellitus and to improve quality of live. However, long term follow up studies show that an important proportion of patients gain weight again. This phenomenon commonly occurs between the third and sixth postoperative year. The main risk factors for weight gain are behavioral and psychological issues, that can be detected in the preoperative assessment. This reinforces the concept that bariatric surgery must be managed by experienced multidisciplinary teams.
