Iron deficiency anemia can be pregnant. Iron deficiency anemia is not serious and generally does not affect pregnancy, but the anemia is serious and may adversely affect fetal development. Women with iron deficiency anemia can take ferrous succinate for iron supplementation during preparation for pregnancy. However, after pregnancy, if the mother has iron deficiency anemia, it may affect the supply of nutrients to the fetus, which may lead to poor fetal development, and may also lead to fetal hypoxia, so women with iron deficiency anemia should be actively treated during the preparation for pregnancy. You can choose ferrous succinate for iron supplementation treatment, but ferrous succinate may lead to nausea, vomiting and other gastrointestinal adverse reactions, women need to use it under the guidance of a doctor.
