Altitude sickness on Kilimanjaro

Altitude sickness is not uncommon on Mount Kilimanjaro, also known as the Roof of Africa in Tanzania, and the highest peak in Africa, and tallest freestanding peak in the world! Towering at an incredible 5895m above sea level, climbing this majestic mountain has its challenges. The most common of them all? Altitude sickness. Altitude sickness on Kilimanjaro and your overall safety on the mountain go hand in hand, and should be taken very seriously. In this article we cover the effects of enduring high altitudes, what to expect and how to overcome it. In this post, we will discuss the effects of being at high altitudes, what to anticipate, and how to overcome them.

The most common challenge of all on Kilimanjaro? Altitude sickness

What is altitude sickness?

Altitude sickness, often known as Acute Mountain Sickness (AMS), is a detrimental health impact of high altitude. At sea level, there is about 21% oxygen in the atmosphere. As you ascend higher up the mountain, the percentage stays constant, but the amount of oxygen molecules each breath reduces. At 12,000 feet (3,600 meters), there are around 40% less oxygen molecules every breath. As a result, the body struggles to adjust and operate normally when there is less oxygen available. Altitude sickness is caused by the body’s inability to adjust rapidly to decreasing amounts of oxygen. Often, climbers make the mistake of getting too high (altitude) too fast (rate of ascent).


Don’t worry, altitude sickness on Kilimanjaro is commonplace. In fact, at elevations over 3,000 meters, more than 75 percent of climbers will develop moderate AMS. Climbing Kilimanjaro is quite likely to cause altitude sickness. Age, gender, and physical fitness have no bearing on your chances of having altitude sickness. Just because you haven’t had it previously doesn’t guarantee you won’t develop it on your next trip. You must be knowledgeable.

Can altitude sickness be avoided?

First and foremost, being adequately prepared for your climb will always bring you one step closer to a successful and stress-free adventure. It is important to understand that there is no way to avoid altitude sickness. There is a prevalent misperception that being physically fit makes you less prone to suffer from altitude sickness. While physical fitness and altitude sickness do correlate, they are not inextricably related. This means that if you are physically fit, your body will be better able to tolerate and handle the stresses of many days of climbing, making any extra altitude sickness symptoms that occur somewhat more manageable.

So, although there is no set protocol for avoiding it entirely, there are a few things you may do to prepare. Climb steep mountains on a regular basis to prepare your body for the challenge. People have also been practicing using altitude masks. This is essentially a mask that simulates the loss in oxygen that you would feel throughout your ascent, allowing you to prepare for it. It’s unknown if this is beneficial in preventing AMS in general, but if you have the opportunity, why not try it?

What are the symptoms of high altitude sickness?

Climbing Kilimanjaro often results in common high altitude sickness symptoms. They are often moderate and develop many hours after ascending to higher elevations. Altitude sickness symptoms have been compared to a nasty hangover, and they are often worse at night when respiratory drive is reduced. Mild symptoms of altitude sickness may include:

The incidence of altitude sickness is influenced by height, rate of ascent, and sensitivity. Acclimatization happens at different rates for each person. Symptoms usually emerge 12 to 24 hours after arriving at altitude. They normally begin to diminish in severity on the third day.

More than 75% of climbers will encounter at least some type of minor altitude sickness on Kilimanjaro.

How to cure moderate symptoms of high-altitude sickness?

Mild altitude sickness symptoms on Mount Kilimanjaro are frequent and readily managed. If necessary, descend. This is the best and most effective therapy. You should relax and drink plenty of fluids. Paracetamol and other pain relievers are also effective. Follow Alice emphasizes the importance of listening to one’s body. We advocate allowing your body to acclimate naturally before using drugs. The NHS recommends traveling with these drugs for altitude sickness:

Acetazolamide may prevent and cure high altitude sickness.

Ibuprofen and paracetamol may help with headaches.

Anti-sickness medicine, such as promethazine, for nausea

There are other natural treatments for moderate altitude sickness on Kilimanjaro. Ginger, lavender oil, garlic, and cloves are some of the options. Mild altitude problems are to be anticipated. They do not interfere with regular activities, and symptoms usually resolve as the body adjusts. You’ll feel better as soon as you adjust, and there will be no long-term adverse effects. This implies you may continue with your ascent.

Please remember that mild altitude symptoms are to be expected

What are severe symptoms of altitude sickness?

It is quite unusual for a climber to encounter anything more than the minor altitude sickness symptoms outlined above. To ensure your Kilimanjaro safety, be informed of any potential risks. Altitude sickness may be lethal if not handled. This is why it is important to convey your symptoms if you are sick. If you have a severe case of altitude sickness, you can have symptoms like:

For your own protection, you must be aware of all possibilities. The following information is provided to reassure you rather than terrify you. We are taking all conceivable measure to ensure that your stay in the acclimatization zone is sufficient before climbing farther. At the same time, our guides have been trained to respond to any emergency. We firmly feel, however, that you should be aware of what may occur and why following your guide’s recommendations is critical.

Descending in an emergency

Severe altitude sickness on Kilimanjaro can only be addressed by descending around 2,000 feet (600 metres) to a lower height. If a climber becomes sick and has to descend, our guides will take him or her down quickly. This is often accomplished by helping or, in extreme circumstances, using a portable stretcher. At Follow Alice, we have a minimum of one guide for every two climbers, which means that there are at least four guides in a group of eight. So, in an emergency, there are always enough guides to ensure that everyone is completely secure and cared for.

They should also be followed up with a trip to the doctor for any required treatment. As previously stated, these more significant side effects are quite uncommon among climbers. Your guide will ensure that you are properly acclimatized. This is accomplished by imposing many acclimatization techniques.

What are HAPE and HACE?

If severe altitude sickness symptoms are neglected, they may result in life-threatening disorders affecting the brain and lungs. This is considered severe altitude sickness. Severe altitude sickness is related with two dangerous conditions: HACE and HAPE. These are very unusual conditions. However, when they do occur, it is mainly due to someone flying too high too quickly or flying too high and remaining there. In both circumstances, a shortage of oxygen causes fluid to seep from the capillary walls into the lungs or the brain. High Altitude Pulmonary Edema (HAPE) causes fluid buildup in the lungs, whereas High Altitude Cerebral Edema (HACE) causes brain swelling due to a shortage of oxygen.

Communication with your mountain crew about how you are feeling is key

What are the best acclimatization procedures?

Certain enough time, your body will adjust to the reduction in oxygen at a given altitude. This is called as acclimatization. It typically takes one to three days at any given altitude. Choosing the appropriate itinerary for the Kilimanjaro trip is crucial. Most Kilimanjaro routes provide an excellent acclimatization profile. However, do not underestimate the consequences of high altitude. At Follow Alice, we have the following acclimatization measures in place to ensure you reach the peak safely.

Climb high sleep low

This essentially entails going to a higher altitude during the day and sleeping at a lower level at night. This acclimatization process is accomplished by well-planned trips. These include afternoon acclimatization treks to a higher elevation (climbing high) before returning to camp (sleeping low). Ndoto Compass revolves on this crucial acclimatization process. We propose the Lemosho route, together with the Northern Circuit and Machame route, for the finest chance to climb high and sleep low. This is seen in the route height map below.

Drink lots of water

When your breathing becomes heavy and rapid, you lose water quicker. We consequently suggest a daily hydration intake of 4-5 liters. Fluid consumption increases circulation and the majority of body activities. As a result, our mountain cuisine includes a variety of soups, hot drinks, and fresh fruits. Check your pee to ensure that you’re drinking enough. Avoid ingesting alcohol throughout your hike.

Climb slowly

Remember that climbing Kilimanjaro is not a race. During the ascent, you will hear your guides say “pole, pole.” This translates as “slowly, slowly” in Swahili. Expect to trek for 4-7 hours every day on your route to the peak, with a summit day hike of 10-14 hours. On summit day, the oxygen level is low. Expect to take one step at a time, literally!
