**8. Conclusions**

BS is the most effective strategy for the treatment of severe obesity and for the resolution of comorbid medical conditions. Post-surgery, patients are at increased risk for nutritional deficiencies which may result in serious complications if they are not recognized and treated promptly. Adherence to multivitamins supplementations is important to prevent such deficiencies. Multidisciplinary approach with close monitoring is the key for the long-term success after bariatric surgery.
