The most common types of anemia in China are, what are the types of anemia?

1. Anemia with reduced erythropoiesis 1) Lack of hematopoietic substances - lack of essential raw materials for the production of red blood cells, such as iron, vitamin B12, folic acid or protein, etc., can also be caused by malabsorption caused by chronic infectious diseases, or increased demand for rapid growth in some children; Such anemias are: iron deficiency anemia, nutritional megaloblastic anemia, etc. 2) Poor hematopoietic function - common aplastic anemia, if the normal hematopoietic tissue is occupied by lymphocytes, leukemia cells and other abnormal substances, it can also make the hematopoietic function low, causing anemia.

2. Hemolytic anemia Hemolysis can be caused by two aspects: internal and external causes of red blood cells. The former is such as fava bean disease caused by red blood cell membrane defects, thalassemia caused by hemoglobin abnormalities; The latter, such as neonatal ABO hemolytic disease, as well as infection, burns, and poisoning, can also destroy red blood cells and cause hemolysis. 3. Hemorrhagic anemia is divided into acute blood loss and chronic blood loss.

The former such as bleeding disorders, hemophilia, idiopathic thrombocytopenic purpura, etc., or traumatic bleeding such as splenic rupture. Chronic blood loss is common in peptic ulcers, tumors, anal fissures, hookworm disease, menorrhagia in women, etc.

Anemia is a common clinical symptom in which the volume of peripheral red blood cells decreases below the lower limit of the normal range. There are two types of anemia: macrocytic anemia and microcytic anemia.

Red blood cells, also known as red blood cells, are often abbreviated as RBC in English in routine laboratory tests, which are the most abundant blood cells in the blood, and are also the most important vectors for transporting oxygen through the blood in vertebrates. Mammalian mature red blood cells are nucleated, which means they have lost their DNA. Red blood cells also do not have mitochondria, they release energy by breaking down glucose.

Oxygen is transported, and a portion of carbon dioxide is transported. Carbon dioxide is dark purple when transporting and bright red when transporting oxygen.

There are many classifications of anemia, which are generally divided into acute anemia and chronic anemia based on the rate of red blood cell progression. According to the morphology of red blood cells, they are divided into macrocytic anemia, normal cell anemia and microcytic hypochromic anemia. According to the difference in hemoglobin content, it is divided into mild anemia, moderate anemia, severe anemia and very severe anemia.

According to the situation of erythroid hyperplasia in the bone marrow, it is divided into proliferative anemia and hypoplastic anemia.
