Anemia is not always caused by a deficiency in elements.

In cases of iron deficiency anemia, it is due to a lack of iron. Megaloblastic anemia occurs because of a deficiency in folate or vitamin B12. However, clinically, there are many other types of anemia, such as aplastic anemia, hemolytic anemia, myelodysplastic syndromes, leukemia, etc. The anemia caused by these diseases is not due to a deficiency in elements, but is due to the diseases themselves affecting bone marrow hematopoiesis, leading to anemia. Therefore, it is necessary to clearly diagnose the cause of anemia in order to treat it effectively.

Iron deficiency anemia is what type of anemia?

Iron deficiency anemia refers to the anemia that occurs when the body's stored iron is depleted and cannot meet the needs for normal red blood cell production. Before the production of red blood cells is limited, the body's stored iron has already been exhausted. However, at this stage, the routine blood tests may not yet show obvious signs of anemia; this condition is then referred to as iron deficiency. The characteristics of iron deficiency anemia include a lack of stainable iron in the bone marrow and other tissues, as well as reduced serum ferritin and transferrin saturation, presenting as typical microcytic hypochromic anemia. Therefore, iron deficiency anemia is a type of microcytic hypochromic anemia and is classified according to the level of marrow proliferation as a hyperproliferative anemia.
