Summary
Pregnancy involves significant changes in blood values, including increased plasma volume leading to hydremia. Iron deficiency anemia is common and treatable with iron supplementation, impacting fetal growth and pregnancy outcomes.
Area of Science:
- Obstetrics and Gynecology
- Hematology
Context:
- Physiological changes during pregnancy significantly alter hematological parameters.
- Understanding these changes is crucial for maternal and fetal health assessment.
Purpose:
- To outline the characteristic changes in hemoglobin and hematocrit during pregnancy.
- To define anemia in pregnancy and discuss its primary cause and management.
Summary:
- Pregnancy is associated with increased erythrocytes and plasma volume, potentially causing hydremia.
- Normal hemoglobin range during pregnancy is 11.5-13.0 (13.5) g/dl; anemia (<11 g/dl) is common, predominantly due to iron deficiency (95%).
Impact:
- Iron therapy or supplementation can effectively reduce the incidence of iron deficiency anemia in pregnancy.
- Deviations from normal hematological values are linked to adverse pregnancy outcomes, including fetal growth retardation.
