Dear Richard, your haemoglobin count is too
high and it is important that you request your doctor to do further tests to
find the cause of the high haemoglobin count. The cause must be found – it is
not good enough to just go and donate blood.
You could possibly have Polycythaemia Vera. Polycythaemia
is an increased number of red blood cells in the blood. In Polycythaemia, the
levels of haemoglobin (Hb) is usually elevated (high).
If you have polycythaemia vera, your bone marrow makes too many red blood cells,
which causes your blood to get too thick. That can make you more likely to have
blood clots, a stroke, or a heart attack. Haemoglobin levels greater than 18.5
g/dL in men suggest Polycythaemia Vera. Production of red blood cells
(erythropoiesis) occurs in the bone marrow and is regulated in a series of
specific steps. Polycythaemia Vera can result from internal problems with the
production of red blood cells. This is termed primary Polycythaemia. If Polycythaemia is caused due to another underlying medical problem, it is
referred to as secondary Polycythaemia. Most cases of Polycythaemia are secondary
and are caused by another medical condition. Primary Polycythaemias are
In rare cases, Polycythaemia Vera may
eventually progress into a form of leukaemia (blood
cancer) known as acute myeloid leukaemia (AML), a type of
blood cancer that begins
in the marrow of the bones (the soft centre where new blood cells grow).
You must remember that you have the right to request to be seen by another
doctor if you are not happy with your current treatment (MCH).
