To understand what is anemia should begin with breathing. Oxygen is inhaled it does not stop at the lungs. This supply of fuel even though the body and brain as well. Oxygen travel to all parts of the body, although blood and precisely in BC That is, red blood cells. Now, the red blood cells formed in the bone marrow of the body and serves as a boat, the oxygen in the blood. BS there is something called hemoglobin, a protein that carries oxygen. To make adequate amounts of hemoglobin requires iron excess. Iron provides the food that we take together with other nutrients. When red blood cells less than anemia should occur in the body. Maybe there are 3 main reasons: the red blood cells lost due to any reason, production of red blood cells more slowly than necessary, and, finally, the body destroys red blood cells. Various types of anemia associated, at least one of these reasons.
Small amounts of bone marrow to replace blood lost for any reason without anemia people. However, in cases where a large amount of blood flowing in a small amount of time, resulting in severe injuries such as, for example, is not possible for the bone marrow to replace red blood cells as quickly as a result of anemia. In addition, small amounts of blood loss during long periods of time can cause anemia. Examples of such situations can be seen in girls who received heavy periods primarily due to lack of iron in food.
Iron deficiency anemia is the most common type of anemia in the United States. This was mainly caused by iron deficiency in the human diet. Adolescents with iron deficiency will reduce the production of hemoglobin and, consequently, low BS. When the red blood cell production base of anemia. Signs of anemia, pallor and fatigue. There may be other reasons which are not enough red blood cells produced in the body. Folic acid and vitamin B-12 is also essential for red blood cell production. How are they in sufficient numbers are also important. Maybe there is a problem with the bone marrow to work, also cause anemia.
Hemolytic anemia occurs when someone has a BS a shorter period. Bone marrow can not produce new blood cells when blood cells die too early. This can be caused by various reasons, including people who have disorders such as sickle cell anemia sphenocytosis. In some cases the immune system can destroy itself REF. In some cases, specific antibodies can form in the blood as a result of a reaction to certain medications or infections, and can attack the red blood cells.
Teenagers get anemia because their iron intake is not growing fast enough to offset growth probably because nutritional needs are more in the process. In the case of girls, they need more iron after puberty and are under threat due to blood loss during menstruation. In some cases pregnancy leads to anemia. In addition, adolescent excessive dieting to lose weight may also be at risk for iron deficiency. Meat eaters especially red meat eaters with a lower risk compared to vegetarians, such as iron-rich meat in it.
