Altitude Sickness on Kilimanjaro

1. Acclimatize Before the Climb

If possible, spend a few days at higher altitudes before starting your trek. This helps your body adjust gradually. If you live at sea level, building up physical fitness before your trip is especially important. Starting healthy, rested, and stress-free increases your chances of a successful climb.

2. Go Slow and Steady

On Kilimanjaro, your guides will remind you: “Pole Pole” (slowly, slowly). Moving too fast puts stress on your heart and lungs, increasing the risk of AMS. You should be able to talk comfortably while walking. If you’re out of breath, slow down.

3. Ascend Slowly

The climb is carefully planned with gradual altitude gains. Routes are designed to allow for steady progress each day, giving your body the time it needs to adjust.

4. Climb High, Sleep Low

Whenever possible, ascend to a higher altitude during the day, but descend slightly to sleep. This proven method aids acclimatization. Some Kilimanjaro routes naturally include this principle, along with extra acclimatization hikes.

5. Stay Hydrated

Dehydration worsens altitude sickness. Drink plenty of water—even when you don’t feel thirsty. Aim for 3–4 liters per day, and consider bringing electrolyte packets to replace lost minerals.

6. Eat Well

Even if your appetite decreases at higher altitudes, eat as much as possible. Food gives you the energy to keep going and helps your body stay warm. At Kilitop Adventure, our chefs prepare nutritious meals that make it easier to eat well on the mountain.

7. Sleep Properly

Sleeping in a tent on a hard surface is not always easy. To prepare, practice camping at home before your climb. The more comfortable you are with sleeping outdoors, the better rest you’ll get on the mountain.

8. Consider Diamox

Diamox (acetazolamide) is a prescription medication often used to prevent altitude sickness. While originally designed for other medical conditions, it’s effective in helping climbers acclimatize. Always consult your doctor before using it, and inform your Kilitop Adventure guides if you plan to take it during your climb.

9. Relax and Stay Positive

Mild altitude sickness is common, but severe cases are rare. Don’t panic if you get a headache—it doesn’t mean something serious. Relax, listen to your guides, and focus on enjoying the climb. A positive mindset plays a big role in a successful summit.

10. Daily Health Checks with Kilitop Adventure

Your Kilitop Adventure guides are trained to monitor altitude sickness symptoms. They perform twice-daily health checks, tracking your oxygen levels, pulse rate, and overall condition. With constant care and professional support, you’re in safe hands throughout the climb.
