Definition: anemia, what is it? Anemia is an abnormally low level of hemoglobin in the blood. Hemoglobin is a protein contained within red blood cells that allows them to carry oxygen in the body via the blood. This is why people with anemia fizzle and tire more quickly, in fact their heart must redouble efforts to transmit the same amount of oxygen. There is talk of anemia when the hemoglobin falls below 140 grams per liter of blood from the newborn, of 130 g / l in adult men and 120 g / l in adult women. However, there are two main types of anemia: central and peripheral anemia anemia. The former are characterized by insufficient production of red blood cells and hemoglobin in the bone marrow. For seconds, however, the production is normal but down occurs due to a significant loss of red blood cells, for example via bleeding, or because of a destruction of these cells, it is called hemolysis.

The causes of anemia This health problem may be due to various causes. But most often, it is linked to a nutritional deficiency of iron or vitamins. Elements that are essential to the production of hemoglobin and functioning of red blood cells. Anemia can also be linked to kidney disease that will disrupt the production of another essential element called erythropoietin. An inflammatory disease or disorder in the bone marrow can also trigger insufficient red blood cells.
