Gastric resection surgery for weight loss is primarily a metabolic weight loss procedure. Metabolic weight loss surgery requires a thorough preoperative examination upon admission, which takes approximately 3-5 days, followed by surgery. The surgery requires general anesthesia, which is used to complete the surgery because it requires the use of a laparoscopic robot. Because of the minimally invasive approach, any operations in the abdominal cavity, including suturing and anastomosis, are performed using advanced instruments, which are more expensive. No food can be eaten for 2-3 days after surgery, and only after gradual recovery can we drink and eat, etc. The amount of infusion and nutritional support will be gradually reduced. The process from admission to surgery to discharge costs about 60,000-70,000 RMB.
