anemia -

Anemia (in Greek: ἀναιμία anaimia, meaning lack of blood, from ἀν- n, "none" + αἷμα haima, "blood") is a state where the number of red blood cells or the amount of hemoglobin (oxygen-carrying protein) in red blood cells is below normal. Red blood cells contain hemoglobin which allows them to transport oxygen from the heart obtained from the lungs, and then deliver it to all parts of the body.

Anemia is a common blood disorder. Some anemia has its basic disease. Anemia may be classified by the shape or morphology of red blood cells, underlying etiology, and clinical appearance. The most frequent causes of anemia are excessive bleeding, excessive red blood cell destruction of hemolysis or lack of red blood cell formation (ineffective hematopoiesis).

A patient is said to be anemic when the concentration of hemoglobin (Hb) is less than 13.5 g / dL or hematocrit (Hct) is less than 41% in men, and Hb concentrations less than 11.5 g / dL or Hct less than 36% in women.
