Characteristics of anemia
Anemia is a blood disorder in which red blood cells - red cells or red blood cells - are less in number or size than normal, have low hemoglobin, or show alterations that affect their operation. Any of these causes need to prevent the transport of oxygen to body cells and carbon dioxide from any cell to the lungs.
The lack of oxygen in body tissues can cause various physical problems, depending on the type of anemia in question and the degree to which it is present. Disorders vary from mild to endanger the life of affected.
The red corpuscles are the cells that give blood its red color. The main function of red blood cells is the transport of oxygen from the lungs to the cells. In order to transport oxygen they have a component called hemoglobin. The hemoglobin, a complex protein that contains iron, is the main component of red blood cells or erythrocytes. The function of hemoglobin that carries oxygen from the lungs to cells of different body tissues. This hemoglobin combines with oxygen to become oxyhemoglobin. Once you download the oxygen in the cells, contains carbon dioxide and carries it to the lungs, making carboxyhemoglobin.
Hemoglobin levels in red blood cells must be high so that they can combine with oxygen. Hemoglobin levels are related to the amount of iron in the body. When, for various reasons, there is little iron, there is a deficiency of hemoglobin that causes some kinds of anemia, such as sideropenic anemia. Other times the changes in hemoglobin structure also produce certain types of anemia, such as sickle cell anemia.
Red blood cells have an average life of about four months. After his death in the spleen and liver, iron is released and reused for the formation of new blood cells produced in the spinal cord. Alterations in marrow or red blood cell production lower than its own destruction is also responsible for certain types of anemia, such as hemolytic anemia.
Types of anemia
- Iron deficiency anemia (sideropenic anemia): This is the most common form of anemia. Due to lack of iron, the body does not produce enough red blood cells.
- Anemia due to lack of Vitamin B12: (Macrocytic anemia) Low levels of vitamin B 12 ( cobalamin) are responsible for the disease.
- Anemia due to bad absorption of Vitamin B12: ( Pernicious anemia) Bad absorption of this component can also cause anemia. It is actually a type of megaloblastic anemia in which there is enlargement of the red blood cells folic acid deficiency.
- Anemia due to lack of folic acid or megaloblastic anemia: Low levels of folic acid cause anemia. It is actually a type of megaloblastic anemia in which there is enlargement of the red blood cells folic acid deficiency.
- Anemia of chronic diseases: Certain diseases produce low levels of iron or advanced destruction of red blood cells, causing anemia.
- Anemia of advanced red blood cell loss. (Hemolytic anemia). The production of red blood cells in the bone marrow is unable to compensate for this loss and a deficit of red cells.
- Anemia by productive incapacity of the bone marrow: (Secondary aplastic anemia) The bone marrow is damaged and can not produce any type of blood cell.
- Anemia by enlargement of red blood cells (megaloblastic anemia) Red blood cells become larger than usual and not functioning well.
- Red blood crescent cell anemia (sickle cell anemia), genetic disorders of hemoglobin changes in the shape of red blood cells that prevents normal operation.
Symptoms of anemia
The symptoms of anemia depend on the type of anemia that question, but in general, we can mention a few symptoms that may appear on all of them:
Continuous fatigue, weakened immune system , bad hair, brittle nails, tingling in hands or feet, loss of appetite, pale skin, irregular heartbeat, insomnia, menstrual disorders, increased chance of infection wounds, etc.
