Several studies indicate that bariatric surgery frequently leads to resolution or improvement of type 2 diabetes in overweight patients. However, the medical postoperative management requires lifelong counselling, monitoring and nutrient supplements in patients in remission as well as in patients who continue to be diabetic. The aim of such management is to avoid nutritional deficiencies, and to delay diabetes relapse by optimizing the control of risk factors. To this end, diet and pharmacological prescriptions, including vitamin and mineral supplements, are indispensable, despite the fact that specific recommendations, until now, have been lacking for these particular patients.
