For other uses, see Anemia (disambiguation). Anemia, also spelled anaemia, is usually defined as a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood. It can also be defined as a lowered ability of the blood to carry oxygen.
Anemia is defined as a lower than normal number of red blood cells (RBCs) or hemoglobin, a protein they contain that transports oxygen to your tissues. Sometimes people refer to anemia as low blood.. The definition of anemia changes throughout life because the normal number of RBCs or hemoglobin changes as we age. Infants start out with high hemoglobin/RBCs, counts that slightly reduce over the first year of life.
