Kilimanjaro Altitude Sickness – A Complete Guide for Climbers
Climbing Mount Kilimanjaro is a bucket-list adventure for trekkers worldwide. But with its staggering height of 5,895 meters (19,341 feet), Kilimanjaro brings climbers face-to-face with altitude sickness—a condition that occurs due to lower oxygen levels at higher elevations. Safaribando is here to help you understand the essentials of altitude sickness on Kilimanjaro, so you can make informed choices, prevent risks, and know what to do if symptoms arise.
1. Understanding Altitude Sickness
Altitude sickness, or Acute Mountain Sickness (AMS), occurs when the body struggles to acclimate to the low oxygen levels at higher elevations. As you climb Kilimanjaro, oxygen levels decrease, causing the body to work harder to deliver oxygen to cells. Symptoms typically appear above 2,500 meters (8,200 feet), with higher altitudes leading to more severe effects. On Kilimanjaro, most climbers experience some level of altitude-related discomfort, but careful management and preparation can mitigate the risks.
2. Types and Symptoms of Altitude Sickness
Mild Altitude Sickness (AMS)
This is the most common form of altitude sickness, affecting many Kilimanjaro climbers:
- Symptoms: Headache, nausea, loss of appetite, dizziness, fatigue, and mild shortness of breath.
- Management: Rest, hydration, and slowing the ascent can usually help manage mild symptoms.
Moderate Altitude Sickness
Moderate symptoms signal that the body is struggling more intensely:
- Symptoms: Persistent headache that doesn’t improve with medication, increased nausea and vomiting, weakness, shortness of breath, and difficulty sleeping.
- Management: If symptoms worsen, consider resting at the same altitude or descending. Medication and oxygen may also be helpful.
Severe Altitude Sickness: HAPE and HACE
Two life-threatening conditions, High Altitude Pulmonary Edema (HAPE) and High Altitude Cerebral Edema (HACE), require immediate descent.
- HAPE (Fluid in the Lungs): Symptoms include breathlessness, chest tightness, coughing, and a bluish tinge to lips or fingernails.
- HACE (Swelling of the Brain): Symptoms include confusion, difficulty walking, severe headache, and impaired consciousness.
For both conditions, immediate descent is critical, as they can be fatal if untreated.
3. Treatment Options for Altitude Sickness on Kilimanjaro
Mild and Moderate Symptoms
- Rest and Acclimatize: The most effective treatment for mild symptoms is rest at the current altitude, giving your body time to adapt.
- Hydration: Drinking 3-5 liters of water per day helps maintain oxygen levels and reduces the risk of dehydration, which can worsen altitude sickness.
- Medication (Acetazolamide - Diamox): This prescription medication is often used to prevent and reduce altitude sickness symptoms. Diamox helps by encouraging breathing at higher altitudes, aiding in acclimatization. Always consult a doctor before using Diamox, as it can have side effects.
Severe Symptoms: Descent and Emergency Oxygen
- Immediate Descent: For severe symptoms, descending 300 to 1,000 meters is the fastest way to reduce symptoms and prevent escalation.
- Supplemental Oxygen: Some trekking companies carry portable oxygen tanks to provide temporary relief from severe symptoms while descending.
- Dexamethasone (Prescription Steroid): In cases of HACE, dexamethasone can reduce brain swelling as climbers descend, but it’s a temporary solution and should only be used under a guide’s supervision.
4. Prevention Strategies for Altitude Sickness
-
Climb Slowly and Choose a Longer Route
- Routes lasting seven or more days, like the Lemosho or Northern Circuit, allow more time for acclimatization, significantly reducing the risk of altitude sickness.
-
Stay Hydrated and Maintain Nutrition
- Drink plenty of water and eat regularly. Avoid alcohol, as it can dehydrate the body and worsen symptoms.
-
Practice the “Climb High, Sleep Low” Strategy
- If possible, consider a hike to a higher altitude before returning to a lower camp to sleep. This practice encourages acclimatization and can lessen the effects of altitude sickness.
-
Pre-Acclimatize with Pre-Climb Training
- Spending time at altitude before climbing Kilimanjaro, or hiking nearby Mount Meru, can help your body adjust to the reduced oxygen levels.
-
Consider Using Acetazolamide (Diamox) Preventatively
- Many climbers start taking Diamox before the ascent to help their bodies adjust, but always seek medical advice before using this medication.

- Emergency Protocols: Trained guides have protocols for emergencies, including evacuation plans, and carry communication devices to call for help if needed.
6. FAQs on Kilimanjaro Altitude Sickness
Q: What should I do if I start to feel unwell during the climb?
A: Notify your guide immediately. Mild symptoms can often be managed by resting, hydrating, and taking pain relievers. However, for any worsening or severe symptoms, descent is essential.
Q: Can anyone get altitude sickness, even if they’re fit?
A: Yes, altitude sickness can affect anyone regardless of physical fitness. High altitude impacts everyone differently, and acclimatization is key to managing the risks.
Q: How do I know if I should take Diamox?
A: Consult a doctor before your climb to see if Diamox is right for you. It can help many climbers adjust to high altitudes, but it also has side effects like tingling in the fingers and toes, nausea, and altered taste.
Q: Will I be able to get help if I develop altitude sickness on Kilimanjaro?
A: Yes, a reputable trekking company like SAFARIBANDO we have a trained support team equipped with oxygen, medical kits, and emergency communication devices. We will assist you and ensure your safety.
7. Final Thoughts
Altitude sickness is a real risk when climbing Kilimanjaro, but with proper preparation, a gradual ascent, and a responsible support team, most climbers can safely and successfully reach the summit. Remember to take your time, listen to your body, and be prepared to turn back if symptoms become severe.
