According to medical terms, altitude sickness in the Mountains Nepal is called Acute Mountain Sickness (AMS or altitude sickness), and it is the main difficulty that trekkers and climbers face in the high altitudes trek of Nepal. This happens when the body has difficulty coping with the decrease in oxygen levels at higher altitudes.
In Nepal, there are mountains known for their high mountains, which are the eighth Mounts over 8000 m. These are Like, Mount Everest(8,848 m.), Kanchanjangha(8,586 m.), Lhotse(8,516 m.), Makalu(8,463 m.), Cho Oyu(8,201 m.), Dhaulagiri(8,167 m.), Manaslu(8,163 m.) and Annapurna(8,091 m.) which provide trekking and climbing adventures. All this is visited by many travelers who climb up quickly without proper acclimatization. Thus, they are at higher risk of altitude sickness.
High Altitude Sickness is not selective, and anyone can be overcome by the bad symptoms even if he/she is young, fit, and a professional traveler. The symptoms develop a few hours to 24 hours after a rapid rise in altitude and include headache, nausea, suffocation, Tiredness, difficulty sleeping, and loss of appetite. If not treated, it can turn into life-threatening medical conditions such as hemorrhagic respiratory failure, High Altitude Pulmonary Edema (HAPE), or High Altitude Cerebral Edema (HACE).
Preventing Acute Mountain Sickness is all about acclimatization, thus the best way to achieve it. This can be prevented through a gradual approach where climbers take a longer time at middle altitude, and adequate water intake will minimize occurrences of the condition. Besides, trekkers are also informed to abstain from taking alcohol and relax in any strenuous activities for the first couple of days of the trek.
Most of the trekking trails in Nepal, like the Everest Base Camp Trek, Annapurna Circuit Trek, Manaslu Circuit Trek, Langtang Valley Trek, And High Altitude Trek, have provided some reserved days for acclimatization. Fascinating areas of Nepal that include mountains, and mainly the High Pass trek, Three High Pass of the Everest Region, are gorgeous but challenging for travelers. A-consciousness of a few of the signs and descending to a lower altitude whenever necessary can help in avoiding complications.
Some CMS (Chronic Mountain Sickness) recommend the trekkers to take certain medications which include acetazolamide more famously known as Diamox, they are advised to contact their guide or a travel agency like Overland Trek Nepal to seek safety precautions. Appreciation of these risks as well as preparation for them enable adventurers to visit Nepal’s famous high-altitude tourist attractions with the modest likelihood of altitude sickness in Nepal.
What is Mountain altitude sickness?
Acute Mountain Altitude Sickness, famously called altitude sickness in Nepal, is a condition that is marked by symptoms like headaches, light-headedness, and fatigue as a result of reaching a high altitude They frequently affect locations at higher altitudes such as the Everest Base Camp, Manslu Circuit or Annapurna Circuit typically above 3,500 meters (11,482 feet). and include headache, nausea, dizziness and fatigue. Without adequate acclimatization, high-altitude sickness appears, and, in its worse forms, it can progress to HAPE or HACE.
Do you get altitude sickness in Nepal?
Of course, altitude sickness is possible in Nepal, particularly if you engage in trekking or other tourist activities at high altitudes like the Ever-popular Mount Everest Base Camp Trek or the Annapurna Circuit or Manaslu Circuit. Also referred to as Acute Mountain Sickness or AMS, this illness occurs when one moves to altitudes of 3,500 meters (11,482 feet). and more without giving the body to adjust to less oxygen concentration.
Altitude sickness manifests itself using symptoms such as headaches, nausea, dizziness, shortness of breath, and fatigue. They can develop within a few hours of attaining these altitudes and could worsen if not managed appropriately. Since the altitude increases quite steeply across Nepal, particularly in the regions of the Himalayas, adequate acclimatization has to be provided to avoid high-altitude illness.
To minimize the effect of high altitude sickness, the following measures should be taken, especially by travelers: Climbing slowly, adequate intake of water, and incorporating rest days in the climb. As obvious when climbing in the magnificent terrains of Nepal, early identification of the symptoms makes the trek much safer and more enjoyable.
How common is altitude sickness?
Altitude sickness in Nepal is very common and affects most travelers who are planning to visit high-altitude regions in Nepal. It often develops in those who climb steep slopes above two thousand five hundred meters without allowing the body to adjust to fit for trekking in the mountains which called Acute Mountain Sickness (AMS), in this condition affects alpine hikers who travel to the most famous trekking regions such as Everest Base Camp, Annapurna Circuit or Manaslu Circuit.
Research indicates that up to 50 percent of hikers and climbers who venture above 3,500 meters (11,482 feet) are likely to develop mild to moderate forms of high-altitude illness, which include headache, nausea, dizziness, and breathlessness. The possibilities are higher above 4500 meters, where risks of severe forms of AMS, including HAPE or HACE if the safety measures are not taken. Reducing the risks involves correct acclimatization, gradual ascent, adequate water intake or drinking water, and adhering to what the body is telling you.
Overland Trek Nepal is always there to help travelers make their dream trips successful without any problems when it comes to setting up the necessary preparations to handle the hurdles with altitude in the beautiful Nepalese mountains.
Symptoms of altitude sickness in Nepal Trekking

What are the causes of altitude sickness?
Altitude sickness, including AMS, happens when the body cannot adjust to low amounts of oxygen, common with high altitudes that stand above 3,500 meters (11,482 feet).
The condition is caused by several factors as highlighted below.
1. Rapid Ascent
- Ascending very quickly to high altitudes without enough acclimatization is the most common cause. The body struggles to adjust to the lower oxygen pressure.
2. Low Oxygen Levels
- At higher altitudes, the air pressure decreases, resulting in less oxygen available for the body to function. This imbalance can disrupt normal physiological processes.
3. Dehydration
- The dry, cold air at high altitudes, combined with increased breathing rates, can lead to dehydration, exacerbating altitude sickness symptoms.
4. Physical Exertion
- Excessive physical activity in low-oxygen environments places additional stress on the body, increasing the likelihood of developing altitude sickness.
5. Individual Susceptibility
- Some people are naturally more prone to altitude sickness due to genetic factors or pre-existing health conditions. There is no way to predict who will be affected because of this all should be serious about it.
6. Lack of Acclimatization
- If we Skip acclimatization days during the trek or climbing, it deprives the body of the opportunity to gradually adjust to lower oxygen levels.
7. Sleeping at Higher Altitudes
- When we Spend the night at a higher altitude than our body is accustomed to can make symptoms more pronounced, as the body continues to adapt while at rest.
8. Weather and Environment
- Cold temperatures, wind, and changes in barometric pressure at high-altitude places in Nepal, such as Everest Base Camp, Manaslu Base Camp, or Annapurna Circuit, can contribute to physical stress, increasing susceptibility.
These causes help trekkers ready and intervene effectively to prevent diseases like altitude illness in the beautiful but difficult mountains of Nepal.
Risk factors of altitude sickness?

- Trakkers are ascending too quickly without allowing the body time to acclimatize, which is one of the most significant risk factors.
- Alpine Tropical places in Nepal like Everest Base Camp, Manaslu Base Camp, Annapurna Circuit, and other high-altitude trekking regions require gradual ascents to avoid symptoms of Acute Mountain Sickness (AMS).
2. Altitude Reached
- The risk increases at elevations normally above 3,500 meters (11,482 feet).
- Trekking to extreme heights like Everest Kala Patthar, Everest Three High Pass, Annapurna Circuit, or Manaslu Circuit involves lower oxygen levels, which can trigger high-altitude sickness.
3. Previous Altitude Sickness Experience
- If you’ve experienced altitude sickness anywhere in the world in mountainous regions before, you are more likely to develop it again.
4. Physical Condition and Fitness
- Being physically fit does not necessarily reduce the risk of altitude sickness. Both seasoned trekkers and beginners are equally susceptible if they ascend too quickly.
5. The Body Lacks sufficient water
- Inadequate fluid intake and dehydration due to increased breathing at higher altitudes can exacerbate symptoms, so we have to know how to maintain dehydration in our bodies.
6. Spending the night at High altitude
- When spending the night at higher elevations without prior acclimatization increases risk as the body continues to adjust during rest.
7. Genetic Factors
- Some people are genetically predisposed to altitude sickness, even if they follow proper acclimatization practices.
8. Excessive engagement in Physical activities
- Engaging in strenuous activities like long hikes without sufficient breaks at higher altitudes adds stress to the body.
9. Age and Health Factor
- While age is not a major factor, pre-existing medical conditions such as respiratory or cardiovascular issues can increase vulnerability.
10. Environmental Conditions
- Cold temperatures, wind, and reduced air pressure in high-altitude places in Nepal make acclimatization harder and amplify symptoms.
By recognizing these risk factors, trekkers can take proactive measures such as acclimatizing, staying hydrated, and following expert guidance from experienced trekking companies like Overland Trek Nepal to mitigate altitude sickness risks.
