In women with iron deficiency anemia, we need iron supplementation therapy, and therapeutic iron is available in two categories: inorganic iron and organic iron. Inorganic iron is represented by ferrous sulfate, and organic iron includes iron dextrose, ferrous gluconate, iron sorbate, and ferrous fumarate, ferrous succinate, iron polysaccharide and other complexes. The adverse effects of inorganic iron are more obvious than organic iron, and oral iron is preferred, including ferrous sulfate and ferrous succinate, which are often taken after meals making the gastrointestinal tract less irritated. In addition, attention should be paid to eating as much iron-rich food as possible, especially red meat and animal liver, which helps replenish iron in the diet. Also note that eating cereals, dairy and tea may inhibit the absorption of iron, while fish, meat and vitamin C can enhance the absorption of iron. Iron therapy should be administered for at least 4-6 months after the hemoglobin has returned to normal, and only after the ferritin has been determined to be normal can the drug supplementation be stopped under the guidance of a physician.
