Altitude Sickness on Mount Kilimanjaro
Causes, Symptoms & How to Prevent It
Climbing Mount Kilimanjaro is a dream for adventurers worldwide. Standing at 5,895 meters (19,341 feet), Africa’s highest peak offers breathtaking scenery, diverse ecosystems, and a sense of accomplishment like no other. But alongside the thrill, climbers face a serious challenge: altitude sickness. Understanding, preventing, and managing altitude sickness is essential for a safe and enjoyable trek.
Whether you’re planning your first climb or are an experienced trekker, this guide provides clear, friendly, and professional advice — helping you reach the summit safely while enjoying every step.
What is Altitude Sickness?
Altitude sickness, also called Acute Mountain Sickness (AMS), occurs when your body struggles to adapt to low oxygen levels at high altitudes. As you climb higher, the air becomes thinner, meaning there’s less oxygen available for your lungs and bloodstream.
If left unrecognized, altitude sickness can escalate into more severe conditions:
- HAPE (High-Altitude Pulmonary Edema): Fluid builds up in the lungs, making breathing difficult.
- HACE (High-Altitude Cerebral Edema): Swelling in the brain causing confusion, disorientation, and potentially life-threatening complications.
While these serious forms are rare, AMS is common among Kilimanjaro climbers — making preparation crucial.
Common Symptoms to Watch For
Recognizing early signs of altitude sickness is key. Symptoms often appear 6–24 hours after ascending above 2,500 meters (8,200 feet). Common warning signs include:
- Headache
- Nausea or vomiting
- Dizziness or lightheadedness
- Fatigue or unusual tiredness
- Shortness of breath
- Trouble sleeping
If symptoms worsen despite rest or slow ascent, descend immediately and seek medical attention. Listening to your body is the best strategy.
How to Prevent Altitude Sickness
While there’s no guaranteed way to avoid altitude sickness, climbers can take steps to minimize risk:
1. Choose the Right Route
Longer routes allow gradual altitude gain and better acclimatization. Kilibound Adventures recommends Lemosho and Machame Routes as they balance scenic beauty with a slower, safer climb.
2. Ascend Slowly
The golden rule: climb high, sleep low. Take breaks during the day, and avoid rapid ascents. Your body needs time to produce extra red blood cells to carry oxygen efficiently.
3. Stay Hydrated
High altitude accelerates dehydration. Drink 3–4 liters of water per day, and limit alcohol or caffeine, which can worsen dehydration.
4. Eat Well
High-energy meals with plenty of carbohydrates help your body cope with physical stress and low oxygen levels.
5. Consider Medication (Optional)
Some climbers use Diamox (acetazolamide) to prevent or reduce symptoms. Always consult a physician before starting any medication.
6. Know Your Body
Pay attention to warning signs. Headaches, nausea, or dizziness are signals to slow down, rest, or descend.
What to Do If You Feel Sick on the Mountain
If symptoms occur:
- Stop climbing immediately.
- Rest and hydrate.
- Descend if symptoms persist.
- Seek medical assistance — guides often carry oxygen and first aid equipment.
Early action can prevent AMS from progressing to more severe conditions.
