Is anemia all iron deficiency? Anemia is a common phenomenon among women and children in China. When we are anemic, our bodies will become weak and sleepy, which will lead to various functions of our whole body being violated to varying degrees. So anemia is all iron deficiency?

Is anemia all iron deficiency? 1 Anemia is not necessarily iron deficiency, but iron deficiency anemia is just a kind of anemia. There are many factors that cause anemia, such as iron deficiency, blood loss, tumor and other chronic diseases. Anemia can be classified according to different characteristics in clinic, for example, according to the morphology of red blood cells, it can be divided into macrocell anemia, normal cell anemia and small cell hypopigmentation anemia.

1. Giant cell anemia: the average volume of red blood cells > > 100fl, and the average hemoglobin concentration of red blood cells is 32%-35%. Common diseases include megaloblastic anemia, hemolytic anemia with reticulocyte hyperplasia, myelodysplastic syndrome and liver diseases. For example, megaloblastic anemia refers to anemia caused by the deficiency of folic acid and vitamin B 12 or some drugs that affect nucleotide metabolism, which can be manifested as anemia, nausea, abdominal distension, diarrhea, memory loss, mild jaundice and so on.

2. Normal cellular anemia: the average volume of red blood cells is 80- 100fl, and the average hemoglobin concentration of red blood cells is 32%-35%. Common are aplastic anemia, pure red cell aplastic anemia, hemolytic anemia, bone marrow anemia and acute hemorrhagic anemia. For example, hemolytic anemia refers to a group of anemia that occurs when red blood cells are destroyed, life expectancy is shortened, and the compensatory ability of bone marrow hematopoiesis is exceeded. The main manifestations are anemia, jaundice, splenomegaly, reticulocytosis and compensatory proliferation of bone marrow erythropoiesis.

3. Small cell hypochromic anemia: the average volume of red blood cells is less than 80fl, and the average hemoglobin concentration of red blood cells is less than 32%. Common anemia includes iron deficiency anemia, sideroblastic anemia and globin production disorder anemia. For example, iron deficiency anemia refers to a kind of small cell hypochromic anemia caused by the imbalance of iron demand and supply, such as insufficient iron intake, iron absorption disorder and excessive iron loss, which leads to the depletion of iron stored in the body, followed by iron deficiency in red blood cells and reduced hemoglobin synthesis.

Iron deficiency in the body can be divided into iron exhaustion, iron-deficient erythropoiesis and iron-deficient anemia. Iron deficiency anemia is the final manifestation of iron deficiency in the body, and it is also the most common type of anemia, mainly manifested as anemia, fatigue, dizziness, palpitation, dry skin, dry hair and easy to fall off.

Is anemia all iron deficiency? 2 the cause of anemia.

1, folic acid deficiency

Folic acid cannot be synthesized in the human body and must be taken from food. Foods rich in folic acid mainly include green vegetables and fruits. Animal liver and kidney. People who often don't eat vegetables, fruits or animal offal are prone to insufficient folic acid intake. Folic acid is one of the raw materials for hematopoiesis, and folic acid deficiency can also cause anemia.

2. Iron supply is insufficient.

The human body needs more iron than normal people, such as growing children, lactating children, pregnant women and lactating women. There is a great demand for iron in special period, but insufficient iron supply can easily lead to iron deficiency anemia.

3. Vitamin B 12 is insufficient.

Human body's vitamin B 12 is mainly supplied by food, and animal food is rich in vitamin B 12, such as liver, meat and kidney. Eggs and milk are next, and the content of vegetables is very small. Therefore, eating only vegetables without eating animal food will also lead to vitamin B 12 deficiency, and the survival time of red blood cells will be moderately shortened. Although megaloblastic cells increase in different stages of bone marrow, it will lead to NDA synthesis defect and heme synthesis disorder, which will lead to megaloblastic anemia.

4. Too much iron loss

With the aging and continuous shedding of gastrointestinal epithelial cells, free iron will be lost. During subtotal gastrectomy, atrophic gastritis and steatorrhea, the rate of epithelial cell renewal increases, so the loss of free iron also increases. Iron deficiency not only reduces heme synthesis, but also leads to iron deficiency anemia.

5. Excessive iron consumption

Because more than half of the iron in the body exists in red blood cells, repeated massive blood loss will significantly consume the iron storage in the body. Gastrointestinal bleeding, excessive menstrual flow and excessive blood loss during pregnancy will all lead to excessive consumption of iron, which will lead to iron deficiency anemia.

Is anemia all iron deficiency? 3 what should I do if I am iron deficient but not anaemic?

First, eat more iron-rich foods, pay attention to eat more iron-rich foods such as lean meat, poultry, animal liver and blood (duck blood, pig blood) and eggs. Bean products also contain more iron, and the intestinal absorption rate is also high, so attention should be paid to intake. The staple food is pasta. Pasta contains more iron than rice, and its intestinal absorption is better than rice.

Second, eat more foods that help iron absorption. Fruits and vegetables can not only supplement iron, but also contain vitamin C, which can promote the absorption of iron in the intestine. Therefore, while eating iron-rich foods, it is best to eat more fruits and vegetables, which also has a good iron supplement effect.

Third, there are many brands of iron supplements, and some iron supplements can be taken properly under the guidance of doctors.

What are the hazards of iron deficiency in human body?

1, susceptible diseases: iron and other substances in the body constitute the human immune system. Once iron deficiency occurs, the immune system will be affected, the disease resistance will be reduced, and it is easy to be infected with various diseases and inflammation.

2. Anemia: Women are prone to anemia due to their special physiological characteristics, and iron plays an important role in enriching blood. Once iron deficiency, female friends are likely to suffer from iron deficiency anemia, leading to premature aging.

In addition, it can also cause dysmenorrhea, infertility and abortion. Even if pregnant, the development of the fetus in the mother's body may be affected, resulting in a high probability of low birth weight and deformed children.

3. Affect intellectual and physical development: Iron plays a vital role in children's growth and development. Ischemia caused by iron deficiency will affect the neural response of the brain, which will lead to mental and physical retardation.

4, emotional irritability: people with iron deficiency are prone to emotional irritability, easy to get angry, and easy to get upset.

5, affecting sexual function: male iron deficiency may also affect masculinity, because iron deficiency anemia will lead to abnormal male androgen secretion, such people in addition to work fatigue, there will be symptoms of oligospermia, infertility.

In most cases, iron deficiency will lead to anemia because iron is an important element in hemoglobin. If iron deficiency is not anemia, it is recommended to supplement iron from daily diet. You can eat more foods that help iron absorption, such as vegetables and fruits, and you can also supplement some foods rich in iron, such as animal liver. If the symptoms of iron deficiency are serious, you can take some iron supplements under the guidance of a doctor.
