Consequences
ОглавлениеIn developed countries, maternal anemia has been associated with increased risk of preterm birth and low‐birthweight infants, as well as neonatal and perinatal death. In addition, maternal complications associated with anemia include preeclampsia, cesarean delivery, postpartum depression, and an increased likelihood for transfusion either intrapartum or postpartum despite equivalent blood loss. Women with anemia are asymptomatic or describe vague symptoms such as fatigue and palpitations; therefore, screening for anemia during pregnancy is recommended regardless of symptoms.
