There are several common anemia?

Anemia refers to the unit volume of blood in hemoglobin (HB) concentrations, erythrocyte count (RBC), and erythrocyte than plot (HCT) lower than the pathological state. Anemia is only a symptom,
Instead of specific diseases.

The classification of a number of anemia.

According to RBC morphological characteristics: RBC primarily on the basis of the average volume (MCV) and the average red blood cell hemoglobin concentration (MCHC) divided into three categories:

1, large cell anemia: MCV> 100fl: such as anemia most normal pigment-belong to this mainly anemia folic acid and vitamin B12 deficiency caused by megaloblastic anemia.

2, the normal cell anemia: MCV> 85-100fl MCHC <31-35%, mainly belonging to anemia such as aplastic anemia, hemolytic anemia and benign type of hemorrhagic anemia, hypersplenism and chronic organ failure caused anemia also is a normal anemia.

3, low pigment-small cell: MCV <85fl, MCHC <30%, there are such anemic iron deficiency anemia, aplastic anemia globulin generation and iron, such as anemia.

According anemia etiology and pathogenesis of anemia will be divided into:

⑴ erythropoietin excessive destruction of red blood cells to reduce ⑵ ⑶ hemorrhagic
