With a height of 5’7″ but a weight of 140 kg, it was not only the eyes of others that bothered him, diet and exercise did not help him, and his health became extremely impaired: mobility problems, high blood lipids, high blood sugar, fatty liver, severe liver function impairment, moderate depression, severe sleep apnea that often woke him up in the middle of the night, severe oxygen deprivation and breath-holding that forced him to resort to a respirator Yang Guang, who was almost at his wit’s end, approached the Department of General Surgery of Shanghai Ninth People’s Hospital. After thorough planning and discussion, the surgical team decided to perform laparoscopic adjustable gastric banding for weight loss (LAGB) on him. After perfect preoperative preparation, the surgery went smoothly and in just half an hour, Yang Guang’s life would start anew through a few mini holes in the abdominal wall. Six hours after the surgery, Yang Guang was out of bed, able to drink water, and had no obvious pain or discomfort, and started eating fluids the next day.
