Lastly the third patient a 37-year-old Hispanic woman presented with dysfunctional uterine bleeding and habitually chewed rubber bands. All three patients presented with hematological parameters diagnostic for iron deficiency anemia. Conclusion Pica has been practiced for centuries without a clear etiology.
