Objective:

To report a case of severe copper deficiency leading to profound hematological abnormalities following revisional SADI-S, emphasizing its significance in the context of bariatric surgery outcomes.

Key Findings:

• Severe copper deficiency was diagnosed post-SADI-S, leading to severe pancytopenia.
• The patient had normal vitamin B12 levels but low ceruloplasmin and other nutrient deficiencies, highlighting the need for comprehensive nutritional assessment.
• Copper supplementation resulted in significant clinical improvement and resolution of hematological abnormalities, underscoring the importance of trace element monitoring.

Interpretation:

Copper deficiency can occur post-bariatric surgery, leading to serious hematological issues, highlighting the need for careful monitoring and supplementation to prevent complications.

Limitations:

• This is a single case report, limiting generalizability and necessitating further studies.
• Long-term outcomes and broader implications of copper deficiency post-SADI-S remain unclear, and potential biases in patient selection should be considered.

Conclusion:

This case underscores the importance of monitoring trace element levels in patients post-bariatric surgery to prevent severe deficiencies and associated complications, advocating for standardized nutritional protocols.
