Climbing Mount Everest is extremely risky. Mount Everest climb dangers start from Base Camp (17,500 feet) and continue to the summit and back down. At base camp, the oxygen level is half of what it is at sea level. This can cause Acute Mountain Sickness (AMS), and in some cases, more serious problems like High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE). Poor sanitation and crowded camps also lead to stomach problems, such as vomiting and diarrhea.
The Khumbu Icefall is one of the most dangerous sections. It is full of moving ice, deep crevasses, and tall ice towers called seracs. Climbers can fall or get hit by falling ice. Rescues are very hard here since helicopters can’t land on the ice.
Between Camp 2 and Camp 3, the climb gets steeper, and the altitude gain is large. This makes altitude sickness worse, especially for those who ignored early symptoms. In severe cases, the brain may swell (HACE), which can be deadly. Descending can be risky in bad weather, so climbers sometimes need treatment on the mountain using special hyperbaric bags (Gamow bags).
Above Camp 4 (26,000 feet) is the Death Zone, where the body cannot function properly. The air is too thin, and climbers suffer from exhaustion, dehydration, and cold. Hypoxia (low oxygen) and hypothermia are common and dangerous. Many climbers stop eating, drinking, or sleeping well.
More people die during the descent than on the way up. After reaching the summit, climbers are often tired and weak, which leads to bad decisions, falls, or sitting down and never getting up. Some even go snow blind due to strong UV rays, making it hard to see and navigate. Additional risks include overcrowding during good weather windows, which can lead to traffic jams at dangerous spots. This delays climbers, increasing exposure to the harsh environment.
