•The increase in blood volume occurs gradually near the end of the first trimester. It peaks at about the 28th to the 32nd week and continues at this high level through the third trimester. As the plasma volume first increases, the concentration of hemoglobin and erythrocytes may decline, giving the woman a pseudoanemia.

Iron absorption may be impaired during pregnancy as a result of decreased gastric acidity, additional iron is often prescribed during pregnancy to prevent true anemia.
