**3. Bariatric surgery**

Bariatric surgery holds an important and well established role in the management of obese and morbid obese patients. Furthermore, it is proved to be the most efficient mode of treatment that provides sustained weight loss in morbidly obese patients.

International medical and surgical societies (International Federation for the Surgery of Obesity (IFSO), European Association for Study of Obesity (EASO), European Childhood Obesity Group (ECOG)) created guidelines in order to assure safe and effective clinical practice in the field of bariatric surgery.
