This is why Everest climbers typically make several trips up and down the mountain to increasingly high elevation camps to acclimate their bodies to high altitude conditions. Other risks to Everest climbers include frostbite and hypothermia from the extreme temperatures, thrombosis or embolisms caused by thickening of blood in response to high altitude, extreme sunburn, and broken bones from falls.
Tragically, at least four have died so far and more than 30 others are reported to be suffering from severe frostbite and other ailments caused by prolonged exposure to Everest's brutal conditions. With several days remaining in the climbing season, and many climbers still preparing to make ascents, the potential for further tragedy is high.
