anemia (uh-NEE-mee-uh)

a condition in which the number of red blood cells is less than normal, resulting in less oxygen being carried to the body's cells.
  

The condition of having too few red blood cells. Healthy red blood cells carry oxygen throughout the body. If the blood is low on red blood cells, the body does not get enough oxygen. People with anemia may be tired and pale and may feel their heartbeat change. Anemia is common in people with chronic kidney disease or those on dialysis. (See also erythropoietin.)
