The recognition of bariatric surgery as a legitimate component of the treatment of obesity and its comorbidities has led to a clear increase in the number of these procedures. It is essential to know the main principles of postoperative follow-up of these patients so as to ensure success and minimize the risks. Indeed, bariatric surgery imposes a modification of eating behavior and exposes the patient to certain complications and nutritional deficiencies. Their nature depends on the type of surgery, which can be either purely restrictive (sleeve gastrectomy) or mixed, i.e. restrictive and malabsorptive (gastric bypass). While surgical complications most often occur early, nutritional deficiencies commonly appear later. In case of associated comorbidities, the follow-up has to be intensified in order to adapt the drug treatment. Pregnancy can only be considered after stabilization of weight and correction of nutritional deficiencies.
