How many types of anemia are there? How many types of anemia are there?

Blood type. 1.Nutritional anemia.

It is mainly caused by the lack of hematopoietic raw materials in the body. The most common is iron deficiency anemia, which is caused by chronic blood loss, certain gastrointestinal disorders, long-term picky eating, etc. Secondly, due to the lack of vitamin B12, folic acid and other straightening raw materials, it causes nutritional megaloblastic anemia and pernicious anemia.

2.Infectious anemia.

Some of the more severe acute or chronic infectious diseases can be complicated by anemia, such as meningitis, viral hepatitis, various purulent diseases, chronic fungal infections, etc. This type of anemia is completely infected**, and the anemia will follow**.

3.Drug-induced anemia.

Certain drugs can cause hemolytic anemia and aplastic anemia. The drugs that are easy to cause hemolytic anemia mainly include primary hydroquinoline, aminopyrine, sulfonamides, methyldopa, rifampicin, isoniazid, sodium p-aminosalicylate, hibernatine, quinine, etc. Drugs that are prone to aplastic anemia mainly include chloramphenicol, cyclophosphamide, maryland, sulfonamides, methotrexate, methazole, aspirin, chloroquine, etc.

4.Neoplastic anemia.

In the process of development, malignant tumors are often complicated by blood and secondary infection, which hinders the digestion and absorption of nutrients; It can also inhibit the hematopoietic function of hematopoietic organs, shorten the lifespan of red blood cells, and eventually cause or aggravate anemia.

5.Renal anemia.

Mainly associated with decreased erythropoietin. Common diseases are chronic glomerulonephritis, chronic pyelonephritis, polycystic kidney, renal tumor, hydronephrosis, etc. Anemia can occur when these diseases progress to kidney failure.

6.Immune anemia.

Autoimmune hemolytic anemia is the most common. Certain immune diseases can cause anemia during the occurrence and development of diseases, such as systemic lupus erythematosus, rheumatoid arthritis, blood transfusion reactions, etc.

7.Endocrine anemia.

It is mainly caused by chronic adrenal insufficiency and hypothyroidism. In addition, hypopituitarism and myxedema often cause mild anemia, and hypogonadism can lead to mild to moderate anemia.

Anemia is divided into many kinds, it is recommended to use Depu Guxue and tea, starting from the blood and qi, which can improve a variety of problems, which is conducive to the long-term continuation of blood replenishment, and can also regulate and replenish blood and replenish qi and blood, fill essence and replenish blood, remove stasis and regenerate new, and improve anemia. It is recommended to use Depu Guxue and tea.

Anemia can be divided into the following according to the pathogenesis

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.

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.

Microcytic hypochromic anemia, such as iron deficiency anemia.

Anemia is a relatively common disease, and there are many classification criteria for anemia, including iron deficiency anemia, thalassemia, megaloblastic anemia, hemolytic anemia, aplastic anemia, etc.

There are different classifications of anemia based on different clinical features:

1.According to the rate of progression of anemia, acute anemia and chronic anemia are divided;

2.According to cell morphology, there are macrocytic anemia, normal cell anemia and microcytic hypochromic anemia;

3.According to the hemoglobin concentration, it is divided into mild, moderate, severe and very severe anemia;

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

1.Iron deficiency anemia: Some reasons increase the body's need for iron, insufficient intake or excessive loss, which can cause iron deficiency in the body, which affects hemoglobin synthesis in red blood cells, causing iron deficiency anemia, which is a type of anemia.

2.Nutritional megaloblastic anemia (megaloblastic anemia): This type of anemia is caused by a lack of folic acid and vitamin B12 that impairs the synthesis of DNA from the DNA in cells.

3.Aplastic anemia: Certain causes cause bone marrow hematopoietic dysfunction or failure, resulting in varying degrees of pancytopenia, anemia, bleeding or infection, called aplastic anemia, which is also a type of anemia.

4.Secondary anemia: This type of anemia comes from other types of hematopoietic tissue and is caused by infection or chronic systemic disease.

5.Hemolytic anemia: This type of anemia occurs when the destruction of red blood cells is accelerated and the hematopoietic function of the bone marrow is undercompensated.

1. The average hemoglobin volume and mean corpuscular hemoglobin are within the normal range, and the average corpuscular hemoglobin concentration is mostly within the normal range, and a few can be slightly lower than normal. A high reticulocyte count can cause haemoglobin volumes to fall outside the normal range. Acute and chronic hemorrhagic anemia, hemolytic anemia, aplastic anemia, etc.

The volume of hemoglobin, mean corpuscular hemoglobin increases, and the mean corpuscular hemoglobin concentration is normal or decreased. This type of anemia is mainly caused by megaloblastic anemia due to folic acid or vitamin B12 deficiency due to various causes, and megaloblastic anemia caused by other causes or metabolic disorders.

The volume of hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were reduced. Iron deficiency anemia, sideroblastic anemia, various types of marine anemia and certain hemoglobinopathies belong to this type of anemia.

His hemoglobin volume and mean corpuscular hemoglobin are low, but the mean corpuscular hemoglobin concentration is normal. This type of anemia includes chronic infection, anemia caused by chronic kidney disease and secondary anemia caused by inflammation, liver disease, endocrine disorders, malignant tumors, etc.

21. Decreased red blood cell production: such as aplastic anemia, pure red blood cell aplastic anemia, myelopathic anemia, megaloblastic anemia, iron deficiency anemia, marine anemia, iron blast anemia and anemia caused by renal failure.

2. Excessive destruction of red blood cells: such as hereditary spherocytosis, immune hemolytic anemia, paroxysmal nocturnal hemoglobinuria, and hypersplenism.

Enter, etc. 3. Blood loss: including anemia after acute blood loss and chronic hemorrhagic anemia.

3. Various primary or secondary aplastic anemias, that is, bone marrow does not proliferate, and peripheral blood is in a state of anemia.

Myeloproliferative status is good, but anemia due to impaired or excessive consumption of red blood cells. For example, iron deficiency anemia, acute hemorrhagic anemia or hemolytic anemia, megaloblastic anemia (anemia caused by impaired DNA synthesis of the red blood cell system due to folate or vitamin B12 deficiency), and ineffective hematopoiesis (i.e., good or active bone marrow proliferation but peripheral blood anemia) are common manifestations of proliferative anemia.

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.

Anemia can be divided into the following according to the pathogenesis

Hematopoietic anemia: e.g., aplasia;

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

Anemia caused by excessive blood in the attention zone: such as gastrointestinal bleeding caused by ulcers or tumors.

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 dyeing sedan anemia.

Microcytic hypochromic anemia, such as iron deficiency wild anemia.

It is recommended to use Depu Guxue and tea, starting from nourishing blood and qi, which can improve a variety of problems, which is conducive to the long-term sustainability of blood replenishment, and can also regulate blood replenishment, replenish qi and generate blood, fill essence and replenish blood, remove stasis and regenerate new, and improve anemia. It is recommended to use Depu Guxue and tea.
