Anemia occurs when the body does not have enough healthy red blood cells, or when the amount of hemoglobin in the blood is low. The red blood cells in the blood carry oxygen throughout the body. A protein called hemoglobin allows the red blood cells to absorb and release oxygen. Without enough red blood cells or hemoglobin, the body doesn't get enough oxygen. Symptoms of anemia may then occur.
