Africa's highest peak, Mount Kilimanjaro, stands at 5,895 meters, and climbing it is an incredible adventure that also brings real challenges. Altitude sickness, known formally as Acute Mountain Sickness or AMS, is among the biggest obstacles trekkers meet. Map Adventure Safari has guided many climbers safely to the summit, and here are our best tips for keeping altitude sickness away so you can enjoy the climb.
When your body has trouble adapting to the reduced oxygen at high elevation, altitude sickness is the result. Headache, nausea, dizziness, fatigue, and shortness of breath are common symptoms. Severe cases can threaten your life, which is why prevention and spotting the signs early are so important.
Keep your pace slow and steady, and don't rush. Guides on Kilimanjaro love the Swahili expression "pole pole", which means "slowly, slowly". A gentle pace lets your body acclimatize step by step and lowers your chances of AMS.
Look for routes that build in extra days for acclimatization, for example Machame, Lemosho, or the Northern Circuit. Longer itineraries that include rest days give you a better shot at a healthy, successful summit.
Drink lots of water, at least 3 to 4 liters a day. Dehydration can make the symptoms of altitude sickness worse. Go easy on alcohol and caffeine too, since both can dry you out.
Carbohydrates and nutritious meals fuel your body. Regular eating keeps your energy up and helps you acclimatize.
Resist pushing too hard, particularly in the first days. Rest frequently and pay attention to how your body feels. Should you start feeling unwell, let your guide know right away.
Acetazolamide (Diamox) is used by some climbers to help prevent altitude sickness. Talk with your doctor before the trip, and go over this option with both your medical professional and your tour operator.
Watch for headache, nausea, dizziness, and trouble breathing. When symptoms get worse or fail to ease with rest, going down may be necessary. Your guide keeps a close eye on everyone in the group.
A lot of routes follow the principle of "climb high, sleep low", meaning you go up during the day and then drop to a lower camp for the night. Your body adjusts to changes in altitude more easily this way.
Once you or anyone in your group shows moderate or severe symptoms, stopping the ascent and resting is essential. Severe AMS calls for an immediate descent and medical attention. You're in safe hands with the professional Map Adventure Safari guides, who are trained to recognize the symptoms and respond properly.
