Precautions (1) Diet adjustment: Diet nutrition should be reasonable, food should be diversified, and recipes should be wide, so you can't be partial to food, otherwise it will lead to anemia due to lack of certain nutrients. Be nutritious and easy to digest. Diet should be regular and temperate, and overeating is strictly prohibited. Eat more foods rich in iron, such as pig liver, pig blood, lean meat, dairy products, beans, rice, apples, green leafy vegetables and so on. Drinking more tea can supplement folic acid and vitamin B 12, which is beneficial to the treatment of giant cell anemia. But iron deficiency anemia is not suitable for drinking tea, because drinking tea is not conducive to the body's absorption of iron. Appropriate supplementation of acidic foods is beneficial to iron absorption. Avoid spicy, cold and indigestible food. Usually you can supplement your body with a nourishing diet. (2) Combine work and rest and carry out appropriate sports activities. Generally, you can eat more blood-enriching items: black beans, Nostoc flagelliforme, carrots, gluten, longan, day lily, spinach, dried radish and so on.
