Obesity has become the most common fatal and the second most common preventable epidemic disease after smoking in the world. Although it causes many morbidities, the psychosocial challenges it creates in the patients and the huge financial burden for its treatment are the main problems. Medical treatment for weight loss is usually inadequate, and surgery has become a major part of morbid obesity treatment. Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), adjustable gastric band (AGB), and biliopancreatic diversion (BPD) are the most common current surgical procedures, and all can be performed laparoscopically. Eating less and early satiety due to the reduction of gastric volume with surgery and the disruption of absorption as a result of the bypass lead to significant weight loss.
