Altitude sickness, also known as Acute Mountain Sickness (AMS), occurs when individuals ascend to high altitudes too rapidly, not allowing their bodies sufficient time to adapt to the reduced oxygen and changes in air pressure. This leads to a lack of oxygen, termed hypobaric hypoxia, reaching the body’s tissues. Symptoms typically appear at altitudes above 2,500 meters if individuals have not given their bodies the necessary time to acclimate to the altitude change. Mild altitude sickness symptoms include dizziness, fatigue, headaches, nausea, vomiting, loss of appetite, a rapid pulse, and shortness of breath.

More severe symptoms can involve chest tightness, confusion, coughing, social withdrawal, difficulty maintaining consciousness, changes in complexion or skin color, walking difficulties, and, ultimately, the risk of falling into a coma or facing a life-threatening situation.

Preparations for High Altitude on Mount Kilimanjaro While physical fitness can certainly provide benefits, the ability to adapt swiftly to varying oxygen levels at high altitudes is largely determined by genetics. Predicting how well an individual will manage in an oxygen-deprived environment remains challenging until they experience such conditions. Apart from acclimatizing by spending time at high altitudes, you can effectively explore the use of high-altitude training systems, which can simulate high-altitude conditions and induce beneficial physiological adaptations. If you’re interested in methods for pre-acclimatization, Gypsy Tanzania Tours can supply you with additional information and guidance on the subject.

  • Prevention Climbers can take precautions to at least minimize the severity of the illness:
  • Climb the mountain gradually with a slow pace;
  • Stopping for a day or two every 600 meters over 2400 meters or include an extra day of acclimatization;
  • Sleep at lower altitude;
  • Drink a lot of fluid;
  • Avoid alcohol and eat regular meals, high in carbohydrates;
  • Be familiar with early symptoms of Acute Mountain Sickness.
  • Diamox** (acetazolamide) 250mg tablets to be taken twice a day from 13,000 feet to the top. This drug is widely used in high-altitude mountaineering and is very highly recommended.
