Iron deficiency anemia induced by magnesium overuse: a

Although in vitro studies show that iron absorption can be inhibited by magnesium laxatives such as magnesium oxide taking oral iron supplements with magnesium laxatives is not considered a clinical problem A 28-year-old woman diagnosed with anorexia nervosa who overused magnesium laxatives was admitted to our hospital to evaluate her refractory iron deficiency anemia (IDA) despite having
