Anaemia results from a lack of red blood cells or dysfunctional red blood cells in the body. This leads to reduced oxygen flow to the body's organs. Symptoms may include fatigue, skin pallor, shortness of breath, lightheadness, dizziness or a fast heartbeat. Treatment depends on the underlying diagnosis. Iron supplements may be used for iron deficiency. Vitamin B supplements maybe used for low vitamin levels. Blood transfusions may be used for blood loss. Medications to induce blood formation may be used if the body’s blood production is reduced.
