Mild anemia in children, called mild anemia, is usually when the hemoglobin is between 120-90 g/L. The clinical symptoms lack specificity and are more difficult to diagnose and detect. Common manifestations 1. Decreased activity: children are not as active as before, their activities are less than before, and they may have symptoms such as panic, shortness of breath and difficulty in breathing after running and jumping exercises; 2. Pale skin and mucous membranes: the face is pale, and the color of the lips and nail bed is not as red as before; 3. Decreased appetite: there is also a certain impact on the digestive system, such as picky eating and anorexia causing insufficient iron intake, which may easily cause iron deficiency anemia; 4. The presence of infection: immunity is reduced, prone to respiratory infections or infectious diseases of the digestive tract. Treatment 1, remove the cause: remove the cause is the key to treatment. Although iron supplementation can alleviate the disease, but the cause of the disease will eventually relapse; 2, dietary treatment: add supplementary foods rich in iron and high absorption rate, such as liver, lean meat, fish, etc.. Pay attention to reasonable dietary mix. Correct bad eating habits; 3, iron therapy: oral iron can be used bivalent iron salts such as ferrous sulfate, ferrous fumarate, ferrous glucose and ferrous succinate. It is best to take between meals, while oral vitamins can promote the absorption of iron. After the hemoglobin reaches normal levels, iron supplements should be continued for about 2 months to replenish the iron stores. In case of anemia and other manifestations, it is important to go to the hospital promptly for routine blood tests to assess whether the child has a mild anemia.
