The climb itself is difficult and takes much planning if it is to be successful. Climbers must take into consideration the weather conditions, and few climb without supplemental oxygen.

Typically, the expedition will take several weeks or longer. A Base camp is usually established near the bottom of the mountain, then 3 to 4 camps at higher levels. At each camp, climbers spend several days in "acclimatization" to get used to the higher altitude. Climbing at high altitudes can be dangerous and without proper acclimitization can cause serious, life threatening medical conditions, including High Altitude Pulmonary Edema (HAPE) and High Altitude Cerebral Edema (HACE) which are caused by fluid collecting in the lungs and brain.

Other medical problems that can occur while climbing the mountain include [[frostbite]], snow blindness and [[hypothermia]].
