Question

Quizplus · Accepted Answer

Polycythaemia that is caused by living in a high-altitude environment is a form of secondary polycythaemia. In this type of polycythaemia, the body produces too many red blood cells as a response to the low oxygen levels in the high-altitude environment. This is different from primary polycythaemia, which is a rare bone marrow disorder where the body produces too many red blood cells without any external cause. Tertiary and relative polycythaemia are not recognized medical terms.
