Migration to low altitude is curative, though not immediate, as the body adapts to the normal oxygen level near sea-level and the haematocrit normalises. Alternatively, bloodletting (phlebotomy) can be performed to lower the haematocrit temporarily; when combined with volume replacement with fluids this can have a longer effect. Medication with acetazolamide, a carbonic anhydrase inhibitor, has been shown to improve<unk>  by reducing erythropoietin and the resulting polycythaemia, which results in better arterial oxygenation and a lower heart rate. Oxygen therapy and training in slow breathing techniques has been shown to reduce symptoms through increasing blood oxygenation.
