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.
The fatality rate on K2 is 27%. If you attempt K2 you have a 1 in 4 chance of dying. Prior to the 2008 tragedy, of the 198 climbers who summitted the peak, 53 died on K2. That is three times the 9% fatality rate on Mount Everest. K2 is, next to Annapurna, the second most dangerous 8,000-meter peak.
