A condition in which the blood doesn't have enough healthy red blood cells. Anaemia results from a lack of red blood cells or dysfunctional red blood cells in the body.

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.
