Unearthing causes of altitude sickness.


Two Scientists from Lausanne University Hospital say that altitude sickness also known as High Altitude Pulmonary Edema (HAPE) could be triggered by the lungs' inability to transport sodium adequately and not by an inflammation of the small blood vessels of the lungs, as it was previously perceived.

The Scientists Scherrer and Sartori attribute the cause of HAPE to a faulty gene that can strike at altitudes of 3,000 metres and above.

Mountaineers who climb too quickly often suffer from the potentially deadly condition where blood pressure increases in the vessels, leading to the lungs, causing fluid retention. That in turn can cause shortness of breath and extreme tiredness, unconsciousness...
