Anemia is indicated when the hemoglobin concentration of pregnant women is below 110g/L. If the hemoglobin level is above 90g/L and below the normal 110g/L standard it indicates mild anemia, if the hemoglobin level is 60-90g/L it indicates moderate anemia, below 60g/L it indicates severe anemia, and below 30g/L it indicates critical anemia. Most of the anemia in pregnant women are iron-deficiency anemia, mainly because the amount of iron needed increases after pregnancy, but the amount of supplementation may be insufficient, so medication is needed for blood supplementation. It is necessary to follow the doctor’s advice to take different iron supplements according to the patient’s specific situation and the severity of the anemia. For anemia during pregnancy, diet should be supplemented with iron-supplemented foods, mainly animal offal, especially liver, which has a high iron content, and others such as lean meat, seafood, eggs, fungus and dates, which have a relatively high iron content, depending on the specific diet to decide how much to eat. It is recommended that liver should be eaten as little as possible because of the high fat content. If more animal offal is eaten, high blood lipids may occur, and patients should judge the amount they should eat based on their blood sugar index or other nutritional indicators. Because the diet of early, middle and late pregnancy are different, problems should be timely to seek medical advice, the doctor will judge as well as guide the pregnant woman according to the specific situation what should be adjusted in a comprehensive way, but also the best choice for the patient’s situation.
