Bariatric surgery has proven its efficacy to obtain a marked and sustained weight loss and dramatically improves metabolic control in obese patients. The frequently observed remission of type 2 diabetes occurs very early, before any marked weight reduction. Increasing evidence suggests that this favourable effect results from profound changes in gut hormones involved in the regulation of energy intake behaviour and glucose homeostasis rather than simply from mechanical food restriction or malabsorption imposed by the surgical procedure. The better knowledge of these pathophysiological mechanisms, especially well studied with Roux-en Y gastric bypass, resulted in recent innovation in the technical procedures leading to a shift from bariatric surgery to metabolic surgery. Such type of surgery is currently evaluated in patients with type 2 diabetes, but with only a moderate obesity (BMI < 35 kg/m2), or even without obesity (BMI < 30 kg/m2). The Belgian Metabolic Intervention (BMI) Study Group would like to contribute very soon to this evaluation in a multidisciplinary approach.

Obesity is one of the most serious worldwide epidemics of the twenty-first century according to the World Health Organization. Frequently associated with a number of comorbidities, obesity threatens and compromises individual health and quality of life. Bariatric surgery (BS) has been demonstrated to be an effective treatment to achieve not only sustained weight loss but also significant metabolic improvement that goes beyond mere weight loss. The beneficial effects of BS on metabolic traits are so widely recognized that some authors have proposed BS as metabolic surgery that could be prescribed even for moderate obesity. However, most of the BS procedures imply malabsorption and/or gastric acid reduction which lead to nutrient deficiency and, consequently, further complications could be developed in the long term. In fact, BS not only affects metabolic homeostasis but also has pronounced effects on endocrine systems other than those exclusively involved in metabolic function. The somatotropic, corticotropic, and gonadal axes as well as bone health have also been shown to be affected by the various BS procedures. Accordingly, further consequences and complications of BS in the long term in systems other than metabolic system need to be addressed in large cohorts, taking into account each bariatric procedure before making generalized recommendations for BS. In this review, current data regarding these issues are summarized, paying special attention to the somatotropic, corticotropic, gonadal axes, and bone post-operative health.
