[Copper deficiency anemia and neutropenia secondary to total gastrectomy]

We report a case of copper deficiency with anemia and neutropenia due to dumping syndrome after total gastrectomy. Parenteral nutrition containing cupric sulfate promptly improved the dumping syndrome, anemia and neutropenia. This case suggests that total gastrectomy with dumping syndrome can cause copper deficiency, and that copper deficiency should be considered when encountering similar patients with severe anemia and neutropenia.
