What is Altitude Sickness?
Altitude sickness, also known as acute mountain sickness (AMS), is a condition that can occur when ascending to high altitudes too quickly. It is caused by the body’s inability to acclimate to the lower oxygen level at high altitudes.
Everest Base Camp Trekking Acclimatisation
If you are trekking to Everest Base Camp, it is essential to be aware of the dangers of altitude sickness and to take steps to prevent it. This involves slowly increasing your exposure to altitude by spending time at lower altitudes before heading to Everest Base Camp. This gives your body time to adjust to higher elevations and can help prevent altitude sickness.
There are a few different ways to go about acclimatization. One option is to trek up to Everest Base Camp over several days, spending a night at lower altitudes. Another option is to fly or drive to a higher altitude and then acclimate a few days before heading to Everest Base Camp.
Symptoms of Altitude Sickness
The symptoms can range from mild to severe. Mild symptoms include headaches, fatigue, loss of appetite, and difficulty sleeping. These symptoms are often called “mountain sickness” and are the body’s normal response to acclimatizing to the altitude.
If left unchecked, mountain sickness can progress to more severe forms of altitude sickness, such as high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). HAPE is a condition in which fluid builds up in the lungs, and HACE is a condition in which fluid builds up in the brain. Both conditions can be fatal if not treated immediately.
It is essential to be aware of the symptoms of altitude sickness and to descend if you begin to experience any of them.
How can you prepare for altitude sickness?
There are a few things you can do to help prevent it. First, it is important to trek slowly, allowing your body time to acclimate to the altitude. Second, make sure to drink plenty of fluids and avoid alcohol. Third, eat high-protein foods and take vitamins B and C. Fourth, use oxygen if needed. Finally, descend if you begin to experience any symptoms of altitude sickness.
How long will it take to recover from altitude sickness?
Recovery from altitude sickness depends on a few factors, such as how high and severe your symptoms are. For most people, however, the symptoms will resolve within a few days to a week. If you experience more severe symptoms, such as HAPE or HACE, it is important to seek medical attention immediately.
High Altitude Cerebral Oedema (HACE)
HACE is a severe and potentially fatal form of altitude sickness. It occurs when fluid builds up in the brain, causing it to swell. Symptoms of HACE include severe headache, confusion, hallucinations, loss of coordination, and vomiting. If you experience these symptoms, it is important to descend immediately and seek medical attention.
High Altitude Pulmonary Oedema (HAPE)
HAPE is a severe and potentially fatal form of altitude sickness. It occurs when fluid builds up in the lungs, causing them to fill with fluid and making breathing difficult. Symptoms of HAPE include shortness of breath, coughing, chest pain, and fatigue. If you experience these symptoms, it is important to descend immediately and seek medical attention.
Treatment for Altitude Sickness
The treatment depends on the severity of your symptoms. You can try taking pain medication and resting at a lower altitude for mild symptoms. If your symptoms are more severe, you may need to descend to a lower altitude and seek medical attention. Severe cases may need to be evacuated by helicopter.
Prevention is the best medicine when it comes to altitude sickness. The best way to prevent altitude sickness is to acclimate to the higher elevation slowly. This can be done by spending a few days at a lower altitude before traveling higher up. If symptoms occur, it is important to descend to a lower altitude and rest. In severe cases, supplemental oxygen or medication may be necessary.
If you are planning on trekking to Everest Base Camp or any other high-altitude destination, it is essential to know the risks of altitude sickness and how to prevent them. By following the tips above, you can help reduce your risk of developing altitude sickness.
What should you bring on your trek to Everest Base Camp to help prevent altitude sickness?
There are a few things you can bring with you to help prevent or treat altitude sickness. First, it is important to bring plenty of fluids, such as water and sports drinks. Second, bring high-protein snacks and foods, such as nuts and energy bars. Third, consider bringing vitamins B and C and oxygen if needed. Finally, make sure to pack any medications you might need, such as acetazolamide or dexamethasone.
How will you know if you are experiencing altitude sickness while trekking to Everest Base Camp?
There are a few key symptoms to look out for when it comes to altitude sickness. These include:

If you experience any of these symptoms while trekking, you must stop and rest. If the symptoms persist, it’s best to descend to a lower altitude.
Our Advice
We recommend spending a few days acclimatizing in Kathmandu before heading to Everest Base Camp if you have the time. This will help your body adjust to the altitude and should reduce your risk of suffering from altitude sickness. Once you’re in Nepal, there are a few things you can do to reduce your risk further:
- Drink plenty of water to stay hydrated.
- Avoid alcohol and smoking.
- Eat light meals and avoid fatty foods.
- Get plenty of rest.
- Listen to your body, and don’t push yourself too hard.
Preventative Medicine
The best way to avoid getting sick while trekking in Nepal is to take preventative steps before starting your journey. First, ensure you are as healthy as possible by getting a check-up from your doctor and ensuring all of your vaccinations are up to date. Secondly, buy travel insurance that will cover you if you get sick and need to be evacuated. Finally, pack a first-aid kit with AMS medication such as Diamox just in case you feel unwell while on the trail.
Insurance (Heli Evacuation)
One of the most important things you can do to prepare for your trek is to purchase travel insurance that will cover you in the event of an emergency. This is especially important if you are trekking to a high-altitude destination like Everest Base Camp, as you may need to be evacuated by helicopter if you become sick. Make sure to read the fine print of your policy carefully so that you know what is and isn’t covered. When it comes to acute motion sickness, prevention is key.
