You can get altitude sickness if you travel to a high altitude too quickly. Breathing becomes difficult because you're not able to take in as much oxygen. Altitude sickness, also called acute mountain sickness (AMS), can become a medical emergency if ignored. Your age, sex, or physical fitness do not affect your likelihood of getting altitude sickness. Also, just because you may not have had it before, this does not mean you will not get it on another trip. So Kilimanjaro Altitude Sickness is a must to consider while Climbing Mount Kilimanjaro.
Symptoms of altitude sickness usually develop between 6 and 24 hours after reaching altitudes more than 2,500m above sea level.
The symptoms are usually worse at night.
Kilimanjaro Altitude Sickness does not only affect mountain climbers. Tourists traveling to cities that are 2,500m above sea level or higher, such as La Paz in Bolivia or Bogotá in Colombia, can also get altitude sickness. It's not possible to get altitude sickness in the UK because the highest mountain, Ben Nevis in Scotland, is only 1,345m.
The best way to prevent getting altitude sickness is to travel to altitudes above 2,500m slowly. It usually takes a few days for your body to get used to a change in altitude.
