Anemia (sometimes called Low Blood) is a condition in which a person's red blood cells are less able to supply oxygen to the body. Key reasons for anemia are:
- loss of red blood cells;
- decreased hemoglobin
(a substance in the red blood cells that carries oxygen throughout the
body and gives the blood its red color) in the blood; and
- a decreased volume or amount of red blood cells.
There are many kinds of anemia. It is not a disease, but a sign that a person with anemia has some other illness or disorder. Iron Deficiency Anemia is the most common type of anemia.
