Anemia can be divided into three categories according to the cause and pathogenesis: one is anemia caused by reduced red blood cell production, such as anemia caused by abnormal hematopoietic stem cells (aplastic anemia), anemia caused by abnormal hematopoietic regulation (myelofibrosis), and anemia caused by insufficient or impaired hematopoietic raw materials (iron deficiency anemia, megaloblastic anemia); the second is anemia caused by excessive destruction of red blood cells; the third is anemia caused by hemorrhagic loss.
