Anemia after bariatric surgery: Can we predict it before and early after surgery?
Learning Objectives:
- Recognize anemia as a common long-term complication following metabolic and bariatric surgery (MBS), even in the presence of relatively stable hemoglobin levels early after surgery.
- Identify key preoperative predictors of long-term anemia, including advanced age, elevated fasting blood sugar, and higher triglyceride levels.
- Understand the role of early postoperative weight loss—particularly at 12 months—as a predictor of future anemia risk, with greater total and excess weight loss associated with increased likelihood of deficiency.
- Interpret receiver operating characteristic (ROC) metrics, including AUC, sensitivity, specificity, and clinically relevant cut-offs, to stratify patients at risk.
- Apply a risk-based approach to postoperative monitoring, enabling earlier identification of patients at higher risk for anemia.
- Integrate findings into clinical practice by implementing targeted nutritional surveillance and individualized supplementation strategies to mitigate long-term hematologic complications after MBS.
