What is anemia?
Anemia is a common blood disorder that occurs when red blood cells is below normal or when the blood hemoglobin concentration is low.
* Hemoglobin – blood element whose function is to distribute oxygen from the lungs to body tissues.
* Hematocrit – the measurement of the percentage of red blood cells are in a specific volume of blood.
Often, anemia is a symptom of a disease rather than a disease itself, and usually develops due to the presence of one of these factors:
* Excessive blood loss or hemorrhage
* Insufficient production of red blood cells
* Excessive red blood cell destruction
* Decreased production and excessive destruction of red blood cells
