When anemia is detected in fifteen weeks of pregnancy, you need to actively take oral iron supplements such as ferrous succinate for iron supplementation treatment, in addition to eating more iron-rich foods, such as lean meat, animal liver and so on. The occurrence of anemia in pregnant women is detrimental to both the pregnant woman herself and the fetus. As the fetus needs sufficient nutrients for growth and development, when a pregnant woman is anemic, the supply of nutrients to the fetus will be affected, resulting in poor development of the fetus. For pregnant women, both fetal growth and anemia increase the burden on the heart and increase the likelihood of heart disease. When anemia occurs in pregnant women, iron supplementation therapy with oral iron supplements, such as ferrous succinate, should be actively administered. However, ferrous succinate may cause nausea, vomiting and other gastrointestinal adverse reactions, and needs to be taken under medical supervision. In addition to oral iron, pregnant women should also pay attention to their daily diet, eat more iron-rich foods, such as lean meat, animal liver and so on. Although the iron in lean meat, animal liver and other foods may have the effect of iron supplementation, but the effective dose of daily consumption intake is limited, generally can not achieve the effect of anemia treatment. If you want to achieve the effect of treatment of anemia, it is recommended to carry out regular treatment under the guidance of a doctor.
