1. Altitude sickness: This is caused by the body's inability to adapt to the low oxygen levels at high altitudes. Symptoms can range from mild headaches, shortness of breath, and fatigue to more severe conditions such as high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE).
2. Frostbite: This occurs when body tissues freeze due to exposure to extremely cold temperatures. Frostbite can affect any exposed body part, but it most commonly affects the fingers, toes, nose, and ears.
3. Hypothermia: This occurs when the body's core temperature drops below 35°C (95°F). Hypothermia can lead to confusion, drowsiness, loss of coordination, and eventually unconsciousness and death.
4. Mechanical injuries: These include fractures, dislocations, and sprains caused by falls, rockfalls, and other accidents.
5. Acute mountain sickness (AMS): This is a mild form of altitude sickness that typically occurs within the first 24-48 hours of ascent. Symptoms include headache, nausea, vomiting, shortness of breath, and fatigue.
6. Cerebral edema: This is a more severe form of altitude sickness that can lead to confusion, disorientation, hallucinations, and seizures. It can be fatal if not treated promptly.
7. Pulmonary edema: This is a condition in which fluid accumulates in the lungs, making breathing difficult. It can be fatal if not treated promptly.
8. Retinal hemorrhage: This is a condition in which blood vessels in the eye burst, leading to vision problems.
9. Snow blindness: This is a condition in which the cornea of the eye becomes damaged due to exposure to ultraviolet (UV) radiation from the sun. It can cause temporary or permanent vision loss.
10. Death: Everest is a dangerous mountain, and climbers can die from a variety of causes, including accidents, altitude sickness, exposure, and avalanches.
