Kilimanjaro Altitude Sickness: A Comprehensive Guide
Climbing Kilimanjaro involves significant altitude gain, which can lead to altitude sickness, also known as Acute Mountain Sickness (AMS). Here’s how to recognize, prevent, and treat it during your trek.
What is Altitude Sickness?
Altitude sickness occurs when your body struggles to adapt to lower oxygen levels at high altitudes. Kilimanjaro’s summit is 5,895 meters (19,341 feet), where oxygen is 40% lower than at sea level.
