Anaemia is the shortage of red blood cells in the body, leading to an inability of the blood to carry oxygen around the body. Symptoms include weakness, lethargy, paleness and breathlessness. It may be caused by a lack of iron in the diet, blood loss, chronic illness, a genetic or acquired disease or defect, or it may be caused by a side effect of medication. Treatment includes homeopathy, massage, vitamin therapy, Ayurveda, Chinese medicine, acupuncture, an iron rich diet, blood transfusions or surgery to correct internal bleeding where it occurs.
