Whats the causes of prolonged high haemoglobin level?
Three causes come immediately to mind. Chronic dehydration, simply drink more fluids, is the simplest. There are two diseases to check for. Polycythemia vera is a increase of all the blood cells in the body. You didn’t mention high white blood cell count or platelet count, so that is unlikely. The third is a genetic disease called hemachromatosis. The body processes iron too well, and the bone marrow makes as much blood as it has iron for. There is no cure, as we can’t change genes. Treatment consists of medications that bind dietary iron so that it is no longer absorbed, reducation of iron in the diet by eliminating or reducing certain types of foods, and (believe it or not) removing blood. I work in a lab, and we have quite a few patients who come in to have a unit of blood taken from their body. The sad part of this is that we nor the American Red Cross can use their blood for transfusion.
