Anemia (also spelled anemia) is a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood, or a lowered ability of the blood to carry oxygen.
Treatment depends on the underlying diagnosis. Iron supplements can be used for iron deficiency. Vitamin B supplements may be used for low vitamin levels. Blood transfusions can be used for blood loss. Medication to induce blood formation may be used if the body’s blood production is reduced.
