What are the types of anemia, please thank you

According to the development rate of anemia, it is divided into: acute anemia and chronic anemia. In front of Kai Sakura.

1. Macrocytic anemia: MCV > 100FL.

2. Normocytic anemia: MCV in 80FL to 100FL.

3. Microcytic anemia: MCV <80FL.

According to the red line hyperplasia of the bone marrow, it is divided into: proliferative anemia and dysplastic anemia.

According to the pathogenesis, it is divided into: anemia with reduced erythropoiesis, anemia with excessive destruction of red blood cells, and hemorrhagic anemia.

2. Normocytic anemia: MCV in 80FL to 100FL.

3. Microcytic anemia: MCV <80FL.

According to the bone marrow erythroid hyperplasia, proliferative anemia, dysplastic anemia, pathogenesis: hypoerythropoiesis anemia, excessive red blood cell destruction anemia, hemorrhagic anemia.

(1) According to the pathogenesis, it can be divided into:

Hematopoietic anemia: e.g., aplasia;

Anemia due to excessive destruction of red blood cells: such as hereditary spherocytosis;

Anemia caused by excessive blood loss: such as gastrointestinal bleeding caused by ulcers or tumors.

2) According to the cell size and morphology, it can be divided into:

macrocytic anemia, such as megaloblastic anemia;

Normal cell anemia, such as poverty lysis, aplasia, etc.;

Simple microcytic anemia such as chronic anemia.

Small cell hypochromic anemia, such as iron deficiency anemia, etc.

There are iron deficiency anemia, hemorrhagic anemia, Lamu hemolytic anemia, megaloblastic anemia, aplastic anemia, etc.

If it is mild anemia, there is no problem, and it is very effective to treat Wang Bo without medication.

Iron supplementation is usually used.

Normal red blood cells have a certain lifespan, about 120 days, in order to maintain the number of red blood cells in the blood circulation, the bone marrow must produce 1 120 cells in the whole body every day to enter the blood circulation as a supplement. Anemia occurs when the function of bone marrow erythropoietic cells decreases and the loss and destruction of red blood cells increases due to insufficient hematopoietic raw materials or some reason. To know common anemia, it is necessary to understand the classification of anemia.

The most common classification method is to divide the red blood cells into three categories: macrocytic type, normal cell type and small cell hypochromic type according to the size of red blood cells and the amount of hemoglobin in red blood cells. The macrocytic type is more common as megaloblastic anemia. Normal cell types include dysmorphic hemorrhagic anemia, aplastic anemia, and hemolytic anemia.

Microcytic hypochromic anemia includes iron deficiency anemia, thalassemia, and sideroblastic anemia. For example, according to the ** and pathogenesis of anemia, anemia can be divided into four categories: decreased red blood cell production, lack of hematopoietic substances, blood loss and excessive destruction. Anemia occurs when the bone marrow affects hematopoietic function for some reason, commonly known as aplastic anemia, renal anemia caused by chronic nephritis uremia, Schiehan syndrome anemia with hypopituitary gland function, anemia caused by hypothyroidism, anemia associated with chronic infection, and various myelopathic anemias, such as leukemia, bone marrow metastases and myelofibrosis.

Deficiency of hematopoietic substances is predominantly iron deficiency anemia, followed by megaloblastic anemia caused by vitamin B12 or folate deficiency. Anemia due to blood loss can be divided into acute and chronic. There is also a large group of hemolytic anemia caused by excessive destruction of red blood cells.

It is further divided into anemias with red blood cell defects, such as paroxysmal hemoglobinuria; Anemia with red blood cell enzyme deficiency, such as hereditary spherocytosis, hereditary elliptical polycythemia, glucose-6-phosphate deoxygenase deficiency, etc.; Abnormal erythroglobin synthesis, such as thalassemia and abnormal hemoglobinopathies. In addition, there are autoimmune hemolytic anemia caused by extrinsic immune factors and various hemolytic anemias induced by drugs, chemical toxins, biotoxins and infections.

How many types of anemia are common? Anemia refers to a pathological state in which the concentration of hemoglobin (HB) per unit volume in the peripheral blood, the number of red blood cells (RBC) and the volume of red blood cells (HCT) are lower than normal. Anemia is only a symptom, not a specific disease.

There are several classifications of anemia. According to the morphological characteristics of red blood cells: the patients are mainly divided into three categories according to the average volume of red blood cells (MCV) and the average hemoglobin concentration of red blood cells (MCHC).

1. Macrocytic anemia: MCV 100FL: Most of this kind of anemia is normal pigment type, and the main cause of this type of anemia is megaloblastic anemia caused by folic acid and vitamin B12 deficiency.

2. Normal cell anemia: MCV 85-100FL MCHC 31-35%, which belongs to this type of anemia mainly for aplastic anemia, hemolytic anemia and benign hemorrhagic anemia, anemia caused by hypersplenism and chronic organ failure. 3. Microcytic hypochromic type:

MCV 85FL, MCCH 30%, iron deficiency anemia, globulin dyspogenesis anemia and sideroblastic anemia belong to this type of anemia. According to the nature and pathogenesis of anemia, anemia is divided into: decreased erythropoiesis, excessive destruction of red blood cells, and blood loss.

There are three types of anemia, hemorrhagic anemia, hemolytic anemia, and hematopoietic anemia. Hemorrhagic anemia: two types of hemolytic anemia: two types of hematopoietic anemia: three types There are seven types in total.

In China's sea level area, adult male HB less than 120g L, adult female (non-pregnant) HB less than 110g L, pregnant women HB less than 100g L have anemia. The severity of anemia is classified according to the following criteria: Hb less than 30 g L, extremely severe; HB30 59B L, severe; HB60 90G L, moderate; Hb greater than 90 g L, mild.

One is thalassemia and the other is iron deficiency anemia.

There are two main categories. One is disease-induced anemia. The second is deficiency anemia.

Iron deficiency anemia, congenital anemia.

Upstairs is more detailed, but there are also hereditary anemias such as "thalassemia" and congenital deficiency of glucose-6-phosphate dehydrogenase (commonly known as fava bean disease).
