Kilimanjaro Altitude Sickness
By Simbo Natai
Kilimanjaro Altitude Sickness is common among trekkers scaling the mountain. Its cause, symptoms, and preventative measures are important to know beforehand so that you can have a smooth climbing experience.
Here, we’ll go over all these Kilimanjaro Altitude Sickness factors along with some golden rules you should follow when Climbing Mount Kilimanjaro.
What Causes Altitude Sickness?
The main causes of altitude sickness when Climbing Mount Kilimanjaro are when you expose yourself to high elevations and high altitudes above 2,400 meters and lack of proper acclimatization.
Since Mount Kilimanjaro’s height is 5,895 meters, this is way above the standard elevation of 2,400 meters. This in turn causes climbers physical distress and difficulty in adjusting to the lower oxygen pressure.
- At these higher altitudes, the air becomes less compressed and thinner causing Mount Kilimanjaro Altitude Sickness.
- It can be severe at times and makes your body weak. This is exactly the reason why you need to ascend the mountain slowly.
- This gives your body plenty of time to adjust to the reduced oxygen levels.
- If the symptoms become severe, there’s the possibility of evacuation or descent.
A Fact – At the summit of Kilimanjaro, you breathe in only half the oxygen compared to sea level.

How Dangerous Is Altitude Sickness On Kilimanjaro?
Altitude Sickness in Kilimanjaro needs to be taken seriously. Be mindful that young, fit, and healthy climbers are also at risk. Everyone acclimatizes at different rates. Thus, no one can predict how each person will react to the higher elevation gains.
Hence, when it comes to the question of How to Prepare for Kilimanjaro Altitude – we advise that you go for a Kilimanjaro Route that has a duration of 8-9 days. For most of the climbers, the rate of ascent is just slow enough that their bodies will have enough time to adjust to the ever-increasing altitude.

Types Of Altitude Sickness
There are three kinds of altitude sickness that climbers tend to experience on Kilimanjaro. Below is an exploration of each of the types:
Acute Mountain Sickness (AMS)
Mild altitude sickness is also referred to as Acute Mountain Sickness. This is on the lower level of the altitude sickness spectrum and isn’t a major issue, though it is unpleasant.
It is a fact that once you climb over the height of 3,000 meters, more than 75% of people will develop symptoms of AMS.
Severe Altitude Sickness – HAPE AND HACE
The two serious conditions connected with severe altitude sickness include:
- High Altitude Pulmonary Edema (HAPE)
- And, High Altitude Cerebral Edema (HACE)
HAPE is the build-up of fluid in the lungs whereas, HACE is the swelling of the brain caused by a lack of oxygen.
These conditions are very rare but when they do occur it is usually because a climber goes too high too quickly. This is why you must descend the mountain right away if you develop severe symptoms. To help you figure out what the mild and severe symptoms are, we’ll move on to the next section.

Symptoms Of Altitude Sickness
There are three different levels of Kilimanjaro Altitude Sickness Symptoms. I.e. Mild, moderate, and Severe. We’ll discuss them in detail below along with ways to effectively counter them:
|SYMPTOMS OF ALTITUDE SICKNESS||MILD||MODERATE||SEVERE|
|Loss of Appetite||-||X||X|
|Shortness of Breath||-||X||X|
|Lack of Coordination||-||-||X|
|Coughing up Blood||-||-||X|
Now that you know what the symptoms of Kilimanjaro Altitude Sickness Symptoms, let’s see some ways you can treat them if the need arises:
Mild – These symptoms tend to disappear if you rest for a day at the elevation level where they originally started to show. This is also the reason why an acclimatization day where you get to climb high and sleep low is important.
Moderate – Descend at least 1,000 feet (300 meters) or more if necessary. Remain at a lower altitude until the symptoms fade away. Once the symptoms subside, you will have properly acclimatized. After that, you can ascend again.
Severe – Seek immediate medical help and take pain relievers and if the need comes, use supplemental oxygen.
Know the types of Kilimanjaro Altitude Sickness
Be in the know about the severity of your AMS symptoms so you can treat them appropriately.
How Is Altitude Sickness Diagnosed?
When Climbing Kilimanjaro, the guides and mountain crew use a pulse oximeter to measure the oxygen saturation levels and pulse rate. This data along with any symptoms that a climber shows, builds up a picture of the situation.
The Lake Louise Scoring System
Lake Louise Scoring System is the basis of most of the diagnoses of a climber’s condition on Kilimanjaro. Our guides also utilize this as a framework when they need to assess the climber’s condition. The scores are of a number and are based on the severity of the climber’s condition.
|For Headaches||For Gastrointestinal Symptoms|
|None at all||Good Appetite|
|Mild||Poor Appetite or Nausea|
|For Fatigue and Weakness||For Dizziness/Light-Headedness|
|Not weak or tired||No dizziness|
|AMS Clinical Functional Scores|
|Not at All|
|Symptoms were present, but they did not force any change in the climb|
|Symptoms forced me to stop the ascent and go down|
|Had to be evacuated to a lower altitude area|
Note - Monitoring your health is essential in Kilimanjaro to ensure early detection of altitude-related issues and prevent life-threatening conditions.
How Do You Prevent Altitude Sickness On Kilimanjaro?
The following are some precautionary measures you can take to prevent altitude sickness when climbing Kilimanjaro:
Walk High, Sleep Low – Climbing high and sleeping low can help prevent the effects of altitude sickness. This makes sure that you get used to the lower oxygen levels on the mountain plus you get to recover gradually overnight while you rest.
Staying Hydrated – We advise climbers to drink at least 3 litres of water per day. A well-hydrated body helps in acclimatization. Altitude sickness on Kilimanjaro resembles the symptoms of dehydration. Thus, remember to drink as much water as you can.
Take the Longer Route – A Kilimanjaro Climbing Route that has an overall duration of more than 8 days is recommended. Taking sufficient time helps you to acclimatize to the high altitude and reduces discomfort, therefore reducing the risk of altitude sickness.
Choosing the Right Climbing Operator – It’s paramount to climb with a responsible climbing operator that has a group of experienced crew and guides. Our team at African Scenic Safaris is made up of Wilderness First Responder guides that always monitor every individual’s altitude acclimatization.
Keep the Daypack Light – Don’t carry on extra weight in your daypack because that will be an unnecessary burden. You can learn more about what to keep on your Kilimanjaro Daypack here.
