Dizziness during anemia is caused by the anemia itself, as the body is in a state of ischemia and hypoxia during anemia, leading to dizziness due to ischemia and hypoxia in the nervous system. In addition to dizziness, there is also a feeling of heavy-headedness and headaches. To quickly improve these symptoms, it is necessary to transfuse red blood cells and correct the anemia. However, after correcting the anemia, due to the limited lifespan of red blood cells, if the cause of the disease is not clearly identified and treated accordingly, the patient will still experience anemia and symptoms like dizziness again.
