Clinical trials: High-altitude Polycythemia
Erythrocytosis, Mountain Sickness
Study of Cobalt's Role in Excessive Erythrocytosis Among High Altitude Dwellers in Cerro de Pasco, Peru
Chronic mountain sickness is characterized by excessive red blood cell production which causes sludging of the vascular system. This high viscosity blood causes heart failure, cognitive dysfunction, and strokes.
