How is anemia caused? How is anemia caused?

Anemia refers to a decrease in red blood cells and hemoglobin, iron deficiency anemia refers to the lack of iron required to make hemoglobin, iron deficiency anemia is one of the most common diseases in infants and young children, especially in children under 2 years old, especially premature infants and twins. Inadequate iron intake. Babies are in the most vigorous period of growth and development, the need for iron is also relatively large, because the iron content in human milk is insufficient, can not meet the needs of infants, if the iron-containing complementary food is not added in time after 4 months, it is easy to lead to iron deficiency, the iron absorption rate in milk is lower than that of human milk, therefore, artificially fed infants are more likely to develop iron deficiency anemia than breastfed infants.

To prevent iron deficiency anemia in infants and young children, it is necessary to choose foods rich in iron, and at the same time, it is necessary to consider the absorption and utilization of iron, such as taking ferrous sulfate, ferrous gluconate, and adding vitamin C to promote the absorption of iron

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.

Anemia is a clinical syndrome in which the total amount of red blood cells in the peripheral blood is lower than normal. Hemoglobin synthesis disorder, iron deficiency anemia, sideroblastic anemia, vitamin B6 reactive anemia, ferritin-containing deficiency anemia.

1.Iron deficiency anemia can be caused by a deficiency of iron in the hematopoietic raw material. Deficiency of folic acid and vitamin B12 can cause megaloblastic anemia.

For nutritional anemia, the most effective way is to supplement with hematopoietic raw materials**. For example, iron**, folic acid supplementation, vitamin B12** will achieve good results;

2. Anemia caused by changes in the hematopoietic environment of bone marrow, such as acute leukemia, myelofibrosis, myelodysplastic syndrome, etc.;

3. Loss of red blood cells, such as hemorrhoidal bleeding, peptic ulcer bleeding, gastrointestinal malignant tumor bleeding, female menorrhagia bleeding, etc., will cause anemia due to red blood cell loss.

The most common type of anemia is iron deficiency anemia, which may be caused by iron deficiency or hyperplastic disorders, and is also related to the diet in life, such as picky eating and malnutrition, and some women may also have anemia symptoms due to excessive menstrual bleeding.

How is anemia caused? Anemia is caused by inability to keep up with nutrition, eat more blood-replenishing things, pig liver cubs, jujubes, etc., these things are beneficial.

1. Disease. Decreased red blood cell production is the main cause of anemia, which can lead to a decrease in the hematopoiesis of the bone marrow, which can lead to anemia.

2. Chronic blood loss.

If women have heavy menstrual bleeding during menstruation, it may lead to iron deficiency and anemia, generally speaking, women's menstrual cycle is about a month, the duration is 5 to 7 days, and the amount of menstrual blood is about 30 ml. From a medical point of view, if the amount of menstrual blood is higher than 80 ml and lasts for more than 7 days, it can be determined that menorrhagia is likely to cause chronic blood loss, which is the main cause of anemia.

3. Iron deficiency during pregnancy.

During pregnancy, the body needs a lot more iron than usual, mainly because the gastrointestinal peristalsis of pregnant women will slow down and lack of gastric acid, which will lead to poor iron absorption, and long-term insufficient iron intake will lead to anemia, and in serious cases, it will also lead to a threat to the health of the fetus.

4. Long-term strenuous exercise.

Sweat contains a lot of iron, and when you sweat a lot during long-term strenuous exercise, it will lead to excessive iron loss. In addition, after strenuous exercise, the red blood cells are damaged, and the muscles will also be damaged to a certain extent, which will cause the loss of iron, resulting in anemia.

5. Irregular life.

When the human body is under greater mental and work pressure, there will be excessive physical exertion, decreased sleep quality, etc., physical health will be threatened, the body's absorption rate of iron will be reduced, and anemia will also be triggered.

6. Diet. If you have the habit of picky eating and picky eating, or do not like to eat meat, it will affect iron absorption, and in the long run, iron deficiency will occur, which will lead to anemia.

To sum up, we have a certain understanding of the causes of anemia, in order to avoid anemia, friends can pay attention to the above six points in life, and prevent it from happening. Friends who have been determined to have anemia can eat as much blood-replenishing food as possible, and at the same time, in special circumstances such as menstruation and pregnancy, pay more attention to diet and rest, and if the situation is serious, it should be timely to avoid aggravating the condition.

The main cause of anemia is a lack of nutrients in the diet, such as iron, folic acid, and protein. In addition, if there is a lot of blood loss, the symptoms of anemia will occur.

Hello, what we call anemia is iron deficiency anemia, which is caused by insufficient iron stores in the body, resulting in a decrease in hemoglobin levels, mostly due to dietary and nutritional iron deficiency, female menstrual blood loss, gastrointestinal malabsorption and other reasons. Iron supplementation is the foundation of improving anemia, you can eat some iron supplements to produce blood, and supplementing anemia for one or two months can basically be corrected. I usually eat pig blood, red meat, shiitake mushrooms, and red dates, which are iron-supplementing foods.

There are many kinds, some are caused by malnutrition, and some are congenital.

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.

The following symptoms usually occur when anemia occurs:

Neurological symptoms: easy to feel dizzy, tinnitus, weakness, depression and even hallucinations when walking. Psychiatric symptoms:

Depression, wanting to sleep, and even mental disorders. Symptoms: When anemia, there are frequent changes, for example, the mucous membranes are pale.

In more severe cases, it may become rough or even ulcerated. Digestive symptoms: bloating, loss of appetite, nausea.

Anemia is only a symptom, which can be caused by the following reasons: 1. Decreased red blood cell production includes lack of hematopoietic substances and poor hematopoietic function. The former, such as iron deficiency anemia, nutritional megaloblastic anemia, etc., is often due to the lack of essential raw materials for the production of red blood cells in the diet, such as iron, vitamin B12, folic acid or protein, and can also be caused by malabsorption caused by chronic infectious diseases, or some children need to increase due to rapid growth, so the best way to avoid anemia is to eat a balanced diet and not be picky.

Aplastic anemia is common in poor hematopoietic function, and if the normal hematopoietic tissue is occupied by abnormal substances such as lymphocytes and leukemia cells, it can also make the hematopoietic function low and cause anemia. 2. Hemolytic anemiaHemolysis 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.

Hemolytic anemia has a common feature, that is, there are different degrees of ** yellow staining, and different degrees of splenomegaly can be found during physical examination. 3. Blood loss 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, anal fissures, hookworm disease, etc., although the amount of blood loss is not large each time, but it accumulates over time, and the total amount is quite large, which can also cause anemia. The aforementioned child not only has a decrease in red blood cells, but also a decrease in granulocytes and thrombocytosis, and after further examination, he was diagnosed with aplastic anemia.

There are many causes of anemia, such as abnormal gray enzyme activity in general diseases.

The most common type of anemia is iron deficiency anemia, which may be caused by iron deficiency or hyperplastic disorders, and is also related to the diet in life, such as picky eating and malnutrition, and some women may also have anemia symptoms due to excessive menstrual bleeding.
