Clinical Significance of Early Postoperative Weight Loss in Bariatric Surgery: A Narrative Review
1Department of Surgery, CHA Bundang Medical Center, CHA University, Seongnam, Korea.
Abstract:
Early postoperative weight loss (EWL) after bariatric surgery is a critical as a powerful predictor of long-term weight loss and metabolic outcomes. This narrative review shows evidence from recent studies examining the biological, behavioral, and clinical implications of EWL in patients undergoing various bariatric procedures. We discuss the hormonal and metabolic adaptations that occur in the first months after surgery, the psychosocial and behavioral factors influencing postoperative outcomes, and how early weight loss can guide individualized management. We further conduct the clinical pathways that integrate EWL monitoring into routine postoperative care. The goal is to encourage standardization in EWL measurement and its integration into multidisciplinary bariatric management to improve patient postoperative outcomes.
