Expert consensus on management strategies for bariatric surgery‑related anemia (2024 edition)

Anemia is a common complication in obese patients and individuals undergoing bariatric surgery. The Chinese Society for Metabolic and Bariatric Surgery, in collaboration with experts in metabolic and bariatric surgery and hematology, organized discussions on the prevention and management of postoperative anemia following bariatric surgery based on existing clinical research evidence. Consensus was reached on the diagnosis, causal analysis, preventive measures, and treat-ment methods for postoperative anemia following bariatric surgery. The formulation of the "Expert Consensus on Management Strategies for Bariatric Surgery‑Related Anemia (2024 Edition)" aims to enhance the awareness of metabolic and bariatric surgeons regarding the prevention and manage-ment of postoperative anemia after bariatric surgery. It seeks to standardize the management of postoperative anemia, thereby reducing the incidence of anemia and driving related research efforts.
