In this case, it is suggested that patients can eat more animal liver after injury, and make soup with red dates and Redmi, which can speed up the blood supply. In addition, it is suggested that patients eat duck blood properly, which can also play a role in enriching blood.

It is suggested that patients must have regular blood routine examination. If the symptoms of anemia are getting lighter and lighter, it is suggested that the drug can be stopped appropriately.

If anemia is more serious, reaching below 60 grams, it is recommended that patients receive symptomatic treatment such as blood transfusion in time.
