Metabolic effects occurring during anabolic steroid therapy in immobilized patients or those with metastatic breast disease include osteolytic-induced hypercalcemia.
Anabolic steroids effect electrolyte balance, nitrogen retention, and urinary calcium excretion. Edema, with and without congestive heart failure, has occurred during anabolic steroid therapy.
