Iron-deficiency anemia and long-term use of copper-bearing IUDs.
The increase in menstrual blood loss (MBL) caused by IUDs may result in iron deficiency anemia.  60 women completing 2 years of Cu-IUD use were investigated for this risk, using hemoglobin concentration serum iron indices.  No significant differences were found compared to a control group of women requesting interval Cu-IUD insertion.  A decrease in the MBL increment with time following insertion, self-selection of the study population, and increased dietary iron absorption are suggested explanations for these results.  15.4% of patients suffered from iron deficiency anemia.  Measurement of serum ferritin is advocated to identify these women for treatment, in order to enhance maternal health.
