How To Navigate Altitude Sickness On Your Everest Base Camp Trek
Embarking on a trek to Mount Everest is a dream for many adventurers, but the challenge of high altitude is a critical aspect to consider. Whether you’re new to high-altitude hiking or an experienced trekker, understanding altitude sickness is crucial for anyone planning Everest Base Camp Treks.
With the right strategies, you can mitigate the risks and ensure a safe and enjoyable journey. This article will provide essential tips on how to overcome altitude sickness, should it arise on your expedition.
What is altitude sickness?
Altitude sickness occurs when you ascend to high elevations where the air pressure and oxygen levels are lower. This condition can affect anyone, regardless of fitness level or previous altitude experience.
It typically manifests when you reach altitudes above 2,500 meters (8,200 feet) and can progress to more severe forms such as high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE) if not managed properly.
Recognising the symptoms
Early recognition of symptoms is crucial for effective intervention. Common symptoms include:
• Headache
• Nausea and vomiting
• Dizziness
• Fatigue
• Shortness of breath
• Swelling of hands, feet, and face
Severe symptoms of HAPE and HACE can include:
• Shortness of breath at rest
• Coughing up white mucus
• Confusion
• Loss of coordination (ataxia)
• Hallucinations and altered mental state

Prevention strategies
1. Gradual ascent
Ascend slowly to allow your body time to adjust. A common guideline is not to increase your sleeping altitude by more than 300-500 meters (1,000-1,600 feet) per day above 2,500 meters (8,200 feet). Try to incorporate rest days to acclimatise properly.
2. Hydration
Stay well-hydrated by drinking plenty of fluids. Dehydration can exacerbate symptoms.
3. Diet and rest
Eat a balanced diet rich in carbohydrates to maintain energy levels, and ensure you get adequate rest to help your body recover and adapt to the conditions.
4. Avoid alcohol and smoking
Refrain from consuming alcohol and smoking, as these can impair acclimatisation and heighten your symptoms.
5. Acclimatisation days
Plan acclimatisation days at key points during your trek. Use these days to take short hikes to higher altitudes, then return to sleep at a lower elevation.
6. Medication
Consider taking acetazolamide to ease symptoms and prevent illness. This medication can help accelerate acclimatisation, but consult with a healthcare provider before starting any medication.
What to do if you experience symptoms
If you begin to experience symptom of altitude sickness, it is vital to take immediate action:
• Do not ascend further: Stay at your current altitude or descend lower if symptoms persist or worsen.
• Rest and hydrate: Ensure you rest adequately and drink fluids to help your body recover.
• Seek medical help: If symptoms are severe, seek medical assistance promptly. HAPE and HACE are life-threatening conditions that require immediate descent and medical intervention.
Navigating altitude sickness requires preparation, awareness, and cautious progress. Always listen to your body, take necessary precautions, and prioritise your health to make the most of this extraordinary adventure.
