Iron deficiency anemia should be treated with iron rich foods such as meat, pig liver, pig blood, duck blood, spinach, etc., as well as oral and intravenous iron supplementation. Iron deficiency anemia is a disease caused by a lack of iron in the body leading to a decrease in the production of red blood cells in the bone marrow, the peripheral blood shows a decrease in red blood cell count and hemoglobin, and a decrease in the volume of red blood cells and other manifestations. Iron supplementation is the treatment for iron deficiency anemia, and can be given with food and medicine at the same time. 1. Meat, pig liver, pig blood, duck blood and other foods are rich in animal iron, which is divalent iron and easily absorbed by the body; spinach and black fungus and other foods are rich in plant iron, which is trivalent iron and needs to be reduced to divalent iron in the body before it can be absorbed. Therefore, you need to eat more meat, pig liver, pig blood, duck blood, spinach, black fungus and other foods in your diet. 2. The effect of food iron supplementation is slow, and it is necessary to take oral iron supplements such as ferrous succinate tablets and protein iron succinate oral solution at the same time, as well as intravenous iron sucrose injection for iron supplementation therapy, which can accelerate the speed of iron supplementation, thus curing iron-deficiency anemia as soon as possible. At the same time, the cause of the disease needs to be clarified, and the treatment should be directed at the cause of the disease. It is recommended that the patient should consult a doctor in time, and under the guidance of hematologist, carry out iron supplementation treatment, and formulate reasonable dietary recipes, as well as regularly review the blood routine to assess the efficacy of treatment.
