What Happens If You Go Too High on Mount Everest?

Life-Threatening Risks

• Altitude Sickness (AMS, HACE, HAPE): Headache, nausea, cerebral/pulmonary edema—can be fatal.
• Hypothermia: Extreme cold overwhelms body heat production.
• Frostbite: Freezing of exposed tissues (fingers, toes, face) → possible amputation.
• Hypoxia: Insufficient oxygen for organ function → cognitive impairment, organ damage, death.
• Barometric Pressure Effects: Low pressure increases heart rate, reduces lung capacity, shifts fluids.
• Exhaustion: Extreme exertion at altitude impairs judgment, increases accident risk.
• Accidents: Falls, crevasses, avalanches, icefalls; difficult rescue/evacuation.

Proper acclimatization, gear, monitoring, and conservative decision-making are essential.
