Anaemia
About This Condition
Anaemia is a general term for a category of blood conditions that affect the red blood cells or the oxygen-carrying haemoglobin they contain.
In anaemia, there is either a reduction in the number of red blood cells in circulation or a decrease in the amount or quality of haemoglobin. There are many causes of anaemia, including severe blood loss, genetic disorders, and serious diseases. (See iron-deficiency anaemia, pernicious anaemia [vitamin B12–related], and sickle cell anaemia.) Anyone with unexplained anaemia should have the cause determined by a qualified doctor.
Some athletes appear to have anaemia when their blood is tested, but this may be a normal adaptation to the stress of exercise,1 which does not need treatment. Further evaluation by a qualified doctor is necessary.
Symptoms
Some common symptoms of anaemia include fatigue, lethargy, weakness, poor concentration, and frequent colds. A peculiar symptom of iron-deficiency anaemia, called pica, is the desire to eat unusual things, such as ice, clay, cardboard, paint, or starch. Advanced anaemia may also result in lightheadedness, headaches, ringing in the ears (tinnitus), irritability, pale skin, unpleasant sensations in the legs with an uncontrollable urge to move them, and getting out of breath easily.
