Pregnant women suffering from iron deficiency anemia may affect the growth and development of the fetus, and at the same time, it will also have adverse effects in the production process. Therefore, the most important thing for pregnant women suffering from iron deficiency anemia is iron supplementation. Two-dimensional ferrous, three-dimensional ferrous oral liquid and iron dextran tablets are commonly used in clinic. If pregnant women can't absorb iron orally or the absorption effect is not good, they can also be treated by intravenous iron supplementation, usually sucrose iron.
