When iron deficiency anemia occurs in children, if the little one is still at the stage of drinking formula, it is important to choose formula feeding with high iron content, and after 4 months of life, iron-rich supplementary food can be added as appropriate, which is beneficial for iron supplementation. Older children can also be supplemented with iron-rich foods, and iron supplements can be used if necessary to enable rapid recovery from iron deficiency anemia. In terms of food supplementation, the first group of iron-rich foods are animal foods, such as egg yolk, lean meat from pork, beef and lamb, and animal liver, such as pig liver, duck liver and chicken liver, which are rich in iron and have a high absorption rate. The second category is plant foods, such as dark-colored foods like black fungus and red dates, as well as dark green vegetables, such as spinach, kale and rape, and fruits like cherries and strawberries, which are also rich in iron and are good for fast iron supplementation. In terms of iron supplementation, clinically more commonly used iron supplements include ferrous sulfate, iron dextran, ferrous succinate, etc., which can achieve the effect of rapid iron supplementation. If your child takes iron supplements, it is recommended to use oral solution as much as possible. Currently, oral solution of iron dextran or oral solution of ferrous succinate is more commonly used, which is more acceptable to children in terms of taste. In addition, while taking iron supplements, you can give your child vitamin C at the same time, because vitamin C can promote the absorption of iron in the intestine, to achieve better iron supplementation effect.
