Obesity is a significant global health issue, and laparoscopic sleeve gastrectomy (LSG) is a common surgical treatment. However, the procedure is invasive and can cause physical and psychological stress, impacting postoperative recovery. Prehabilitation, a process of enhancing a patient's functional capacity before surgery, has shown promise in various surgical fields. This study investigates a "triad prehabilitation management mode," incorporating psychological intervention, nutritional support, and exercise training for patients undergoing LSG. This prospective, randomized controlled trial enrolled 120 patients assigned to either a prehabilitation group or a control group. The prehabilitation group received a structured program of exercise, nutritional guidance, and psychological support for 5-7 days before surgery, in addition to routine care. The control group received routine care only. The study hypothesizes that the prehabilitation strategy will lead to faster gastrointestinal function recovery, better weight loss outcomes, improved quality of life, and a lower rate of postoperative complications compared to routine care.
