According to its etymology, which leads us to the language Greek the anemia refers to the "Lack of blood" . It's about a health disorder which implies a reduced hemoglobin level and usually of Red blood cells in the bloodstream

This pathological state can be seen through an analysis of blood . By studying the fluid in a laboratory, it is possible to detect if the amount of hemoglobin is less than normal. It is important to keep in mind that anemia is not considered a disease: it is a clinical sign It can appear for various reasons.

When a person you have anemia, you may feel that lacks strength and energy and that he lacks the air. This is because hemoglobin has as its main function the transport of oxygen to the different organs of the body , in addition to giving the blood cells their characteristic color. Thus, in the face of anemia, the organs do not access the oxygen they need for proper functioning.

Although there are several parts of our body that collaborate with the production of red blood cells, this important task focuses mainly on the bone marrow, the tissue soft that is inside the bones and that serves to generate blood cells.

The life of healthy red blood cells lasts for a minimum of ninety and a maximum of one hundred and twenty days. When they reach old age, the body is responsible for eliminating them in different ways. It is then that a hormone generated in the kidneys called erythropoietin It emits a signal that reaches the bone marrow and tells you to create more red blood cells.

Since for the creation of an acceptable number of red blood cells our body needs certain minerals, nutrients and vitamins , among which folic acid and vitamin B12 stand out, it is correct to say that the lack or insufficiency of any of them is one of the causes of anemia. The reason for this anomaly, on the other hand, can be one of the following:

* any alteration in the lining of the intestines or stomach that may affect the way in which nutrients are absorbed. A very common example is the celiac disease , a disease that occurs when the lining of the small intestine is damaged by the consumption of gluten;

* food deficiency We often downplay the quality or variety of the food we eat, focusing primarily on satisfying us, but the lack of responsibility in this aspect of our lives is the origin of many disorders, including anemia;

* a surgical intervention to perform the removal of a part of the intestines or stomach.

In addition to the lack of sayings nutrients Anemia can arise as a result of the action of some medications, of problems in the immune system, of the prolongation of diseases such as cancer or rheumatoid arthritis, of disorders in pregnancy or of a sudden loss of large amounts of blood.

The iron deficiency It is another of the most common causes of anemia. In this case, we talk about iron deficiency anemia and it may be due to hemorrhages or insufficient consumption of iron foods. Iron deficiency anemia, for example, may appear in women who experience an alteration in their menstrual cycle.

Due to its characteristics, iron deficiency anemia is part of the calls nonhemolytic anemias . On the other hand, when anemia is due to a hemolysis disorder that causes the drop in the level of red blood cells, it is classified as hemolytic anemia .

The sickle cell anemia , the aplastic anemia and the megaloblastic anemia are others of the types best known of this disease.
