What causes anemia in the body?

The anemia we refer to is basically iron deficiency anemia, what is this anemia and what causes it? Iron deficiency anemia is a type of microcytic hypochromic anemia caused by insufficient iron stores in the body, which affects hemoglobin synthesis. Iron deficiency anemia can be caused by many causes, such as malnutrition, iron deficiency, iron malabsorption, and chronic or acute blood loss.

Pairing two cups of Depu Guxue and tea every day is a good way to regulate and improve the symptoms of qi and blood deficiency.

What's going on with anemia:

Anemia can cause low hemoglobin, resulting in a decrease in the ability of hemoglobin to carry oxygen, due to insufficient oxygen supply, more blood flow in the body to important organs, and those organs that have little temporary impact, such as **, mucous membranes, etc., blood vessels begin to contract. As a result, there is often whitening of the mucous membrane in the eyelids. This phenomenon is especially noticeable on parts of the lips, nails, and earlobes.

Unable to supply enough oxygen to the cells, the body suffers from shortness of breath, rapid heartbeat, fatigue, fatigue, loss of appetite, and drowsiness. In addition, it is easy to cause hypoxia in the brain, affect normal thinking, make thinking ability worse, forgetfulness, and often appear dizzy, dizzy, tinnitus, etc.

Cause of anemia 1:

Iron is an important trace element in hematopoiesis, and dietary iron deficiency is the main cause of anemia. Malnutrition anemia mainly refers to severe iron deficiency in the body, followed by anemia caused by lack of vitamin B12, especially the lack of iron, protein, vitamin B12 and other hematopoietic raw materials in the body caused by picky eating.

Cause 2 of anemia:

Iron deficiency anemia can also be caused by iron malabsorption or loss of iron, such as hookworm infection, gastrointestinal malabsorption, bleeding from gastric and duodenal ulcer disease, hemorrhoidal bleeding, menorrhagia in women, and functional uterine bleeding during puberty.

Cause 3 of anemia:

Blood loss is the most common cause of anemia and can be divided into acute and chronic. Chronic blood loss often causes iron deficiency anemia; Anemia caused by massive blood loss in a short period of time due to rupture of blood vessels or defects in hemostasis mechanisms due to trauma or disease processes is called acute hemorrhagic anemia.

Nowadays, there are many patients with anemia, and the vast majority of them are women. There are different types of anemia, and the most common causes of anemia are usually the following.

1. Iron is an important trace element in the human body, and it is also an indispensable factor in the hematopoietic process. When the human body is deficient in vitamin B12, it can also lead to anemia. Especially in people who are picky eaters and picky eaters, their bodies are deficient in iron, protein, vitamin B12 and other elements needed for hematopoiesis.

2. Some patients do not lack iron in their diet, but the body's poor absorption and serious loss of iron can easily lead to anemia. For example, poor gastrointestinal absorption, ulcer disease, hemorrhoids, as well as heavy menstrual bleeding in women, functional uterine bleeding, etc., can lead to the appearance of anemia.

3. A large amount of blood loss in the human body will also cause anemia, and it is also likely to cause anemia due to factors such as surgery and trauma.

The above is the most common cause of anemia. You can take some preventive measures accordingly to effectively prevent anemia.

Anemia is when the number of red blood cells and the amount of hemoglobin in a certain volume of blood are lower than the normal range. Anemia is a syndrome that can occur in many disorders. There are three main causes of anemia:

Poor hematopoietic function (often due to stem cell defects, insufficient hematopoietic raw materials, invasion of bone marrow by foreign cells or substances, etc.), excessive destruction of red blood cells, and blood loss. Hemoglobin is the carrier of oxygen infusion, so systemic tissue hypoxia symptoms can occur after anemia, such as dizziness, fatigue, loss of appetite, palpitations, and shortness of breath after activity.

Patients with anemia must find out the cause before prescribing the right medicine.

Prescription] 1 There are many causes of anemia, and you should carefully check ** to prescribe the right medicine, and don't take "blood tonic medicine" casually.

2 Patients with anemia should not be picky eaters, but should regularly consume foods rich in iron and folic acid, such as green vegetables, eggs, meat, fish, fruits, etc.

3 During the growth and development of children and women during pregnancy and lactation, there is a large need for hematopoietic substances, and nutrition should be strengthened, and if the food supplement is insufficient, oral iron and folic acid can be taken under the guidance of a doctor.

4 Women with excessive menstrual bleeding should also supplement iron in time, and should find out whether there is a ** disease, cure the ** disease first, plug the bleeding hole, and the anemia can be recovered. Patients with hemorrhoidal bleeding or hookworm disease should be prompted**, otherwise long-term chronic bleeding will also lead to iron deficiency anemia.

5. After gastric and small intestine surgery, chronic gastritis and gastric acid reduction will cause hematopoietic factor deficiency, and attention should be paid to examination, if anemia is found, it should be active**.

6. The elderly must go to the hospital to find out if they have anemia, so as to prevent missing tumor diseases.

1.The main cause is malnutrition.

Malnutrition and anemia mainly refer to the severe iron deficiency of the body, resulting in anemia symptoms, mainly caused by excessive diet control or **. People who do not eat meat, eggs, milk, and only eat vegetables and radishes for a long time can easily lead to anemia.

2.Iron deficiency anemia.

The most important trace element in hematopoiesis is iron, and the lack of iron in the human body will affect hemoglobin synthesis and cause hypochromic anemia, so anemia must be supplemented with iron first.

3. The most common anemia is blood loss.

The most common anemia is blood loss, but hemorrhagic anemia is acute and chronic, and slower blood loss is like a female friend having a period once a month; Acute blood loss refers to anemia caused by the rupture of blood vessels during trauma or disease, resulting in a large amount of blood loss in a short period of time.

4.Aplastic anemia.

People with diseases such as tuberculosis, liver and kidney diseases, and leukemia are prone to aplastic anemia, because of anemia caused by decreased bone marrow hematopoiesis, and this damage is huge for patients.

5.Hemolytic anemia.

Hemolytic anemia is relatively rare because the destruction of red blood cells is accelerated and the bone marrow is inadequate; This situation is caused by mechanical, physical, biological, chemical and other factors.

What causes anemia: 1. Lack of hematopoietic raw materials, 2. Repeated blood loss in women during menstruation, 3. Abnormal bone marrow hematopoiesis, 4. Rheumatism, immunology, kidney disease and some chronic diseases can lead to secondary anemia in patients.

Hello, there are many kinds of anemia, there are iron deficiency anemia, thalassemia, dystrophic anemia. It is recommended that you go to the hospital for a check-up, find out the cause and symptoms**, and eat more vegetables and fruits. Pay attention to the reasonable combination of diet.

Hematopoietic stem cell function declines, or is caused by congenital deficiency.

Anemia, in some people, is genetically determined because hereditary anemia.

There are various causes of anemia, generally including the following: 1. Lack of hematopoietic raw materials, some patients are worried about high blood lipids and do not consume red meat, which may lead to the loss of B12 in the body, resulting in macrocytic anemia; 2. Repeated blood loss in women during menstrual period can also lead to anemia; 3. Abnormal bone marrow hematopoiesis; 4. Rheumatological diseases, kidney diseases and some chronic diseases can lead to secondary anemia in patients.

There are many causes of anemia, and it is recommended to drink Guxuehe tea to replenish yin blood, which is to supplement the deficiency of human life substances and increase the nourishing effect of nutrition.

It can be considered in several ways:

First, the intake is insufficient, and people with a single diet or anorexia are prone to appear.

The second is that the body does not absorb and utilize enough, such as suffering from more serious gastrointestinal diseases.

The third is excessive blood loss, acute bleeding or chronic blood loss such as excessive menstrual bleeding in women, ulcers, hemorrhoids and other bleeding.

Fourth, diseases of other systems of the body, such as blood diseases.

Why is anemia? What are the causes of anemia.

Anemia is not an independent disease entity, but a clinical syndrome secondary to a variety of diseases, and its pathogenesis can be summarized into three categories: insufficient or decreased erythropoiesis, excessive destruction of red blood cells, and blood loss.

First, the main **.

1. Insufficient or decreased production of red blood cells: The production of red blood cells mainly depends on three factors, namely hematopoietic cells, hematopoietic microenvironment and regulatory factors and hematopoietic raw materials. Abnormalities in either factor can cause underproduction of red blood cells.

1) Bone marrow failure: including decreased number or quality defects of hematopoietic stem progenitor cells, such as aplastic anemia, pure red blood cell aplastic anemia, Fanconi anemia, primary myelofibrosis, etc.

2) Ineffective hematopoiesis: including acquired and hereditary ineffective hematopoiesis, the former such as myelodysplastic syndrome, and the latter such as congenital erythroid hematopoietic dysanemia.

3) Bone marrow inhibition: such as radiation ** or chemical ** of the tumor causes damage to hematopoietic cells.

4) Bone marrow infiltration: such as hematological malignant tumors and tumor bone marrow metastasis, which can directly cause the reduction of effective hematopoietic tissue of the bone marrow.

5) Abnormal hematopoietic regulatory factors: such as the decrease in EPO synthesis caused by chronic renal failure, and the increase of negative hematopoietic regulators such as tumor necrosis factor and interferon and iron metabolism regulators in chronic anemia.

6) Abnormal hematopoietic microenvironment: The hematopoietic microenvironment is composed of a variety of stromal cell components, macromolecular bioactive substances, microcirculation, neuroendocrine factors and the complex network between them, which provides the necessary conditions and places for the differentiation, development, proliferation and maturation of hematopoietic stem cells. The exact significance of hematopoietic microenvironment in the pathogenesis of anemia is poorly understood, but it may play a role in the pathogenesis of some anemias such as aplastic anemia.

7) Deficiency of hematopoietic substances: Deficiency of folic acid and/or vitamin B12 leads to impaired cellular DNA synthesis and causes megaloblastic anemia. Iron is an important substance for the synthesis of hemoglobin, and iron deficiency can cause iron deficiency anemia.

2. Excessive destruction of red blood cells: The common feature of this type of anemia is the shortened lifespan of red blood cells, which is called hemolytic anemia. Red blood cell destruction mainly involves two main mechanisms: red blood cell intrinsic and extrinsic red blood cells.

1) Intrinsic defects of red blood cells: The basic structure of red blood cells includes cell membranes, metabolic enzymes and hemoglobin, and abnormalities or defects can shorten their lifespan.

The latter includes a variety of non-immune factors, such as physical (mechanical, temperature, etc.), chemical (chemical toxicants, drugs, metabolic and biotoxins, etc.), and biological (microbial infections).

3. Blood loss: including acute blood loss and chronic blood loss. Acute blood loss is mainly due to hemodynamic changes, and chronic blood loss is the most common cause of anemia.

2. Predisposing factors.

1. Environmental factors: long-term exposure to pesticides, hair dyes, rays and other chemicals.

2. Disease **: patients with malignant tumors or other chronic diseases will cause damage to hematopoietic cells when receiving chemical **.

3. Dietary factors: Lack of folic acid and vitamin B12 caused by unbalanced diet will induce cell DNA synthesis disorders and cause megaloblastic anemia; Picky eating, etc., cause insufficient iron intake, leading to iron deficiency anemia.

Irregular diet, caused by malnutrition, usually more ideas about eating habits, balanced nutrition is enough.

There are many causes of anemia, which are mainly divided into five aspects: first, the lack of hematopoietic raw materials, such as iron, folic acid, vitamin B12 caused by iron deficiency anemia, megaloblastic anemia, etc. Second, the hematopoietic function of the bone marrow decreases, such as blood diseases, myeloma, aplastic anemia, etc.

Third, erythrocyte growth factor deficiency, such as renal anemia. Fourth, the lifespan of red blood cells is shortened, and red blood cells are destroyed the most, such as thalassemia, sickle red blood cell anemia, and hypersplenism causes increased red blood cell destruction. Fifth, hemorrhagic anemia.

Anemia can be classified as severe according to the value of hemoglobin in the blood routine, less than 30 g l is extremely severe anemia; 30-60 g l is severe anemia; 60-90 g l is moderate anemia; Mild anemia below the normal value above 90g L; You can drink two cups of Depu blood and tea every day to adjust the physiological functions of the body, promote the smooth flow of blood, qi and blood, reconcile camp and health, balance yin and yang, and effectively prevent it.

Anemia is classified according to the mechanism of occurrence and **

1. Anemia with reduced erythropoiesis.

1) Stem cell abnormality is anemia caused by bone marrow hematopoietic failure, such as aplastic anemia and myelodysplastic syndrome.

2) Anemia caused by abnormal hematopoietic regulation (nutrient deficiency), such as lack of food, malabsorption, increased need, etc.

2. Anemia and hemolytic anemia caused by excessive destruction of red blood cells.

3. Excessive loss of red blood cells, such as hemorrhagic anemia.

Clinical manifestations include eyelid paleness, body aches and weakness, dizziness, headache, dizziness, insomnia, and dreams.

There are other typical anemias such as iron deficiency anemia, megaloblastic anemia due to vitamin B12 deficiency, folic acid deficiency megaloblastic anemia, sickle cell anemia, and other specific symptoms.

Therefore, anemia is only a symptom, and the disease that causes anemia is the root of the disease.
