Altitude Sickness (Acute Mountain Sickness) (AMS)
Mastering the Heights: Your Trusted Guide to Altitude Sickness in the Himalayas
The majestic Himalayas are as awe-inspiring as they are demanding. When exploring the skyward trails with Adventure Hub Nepal, one crucial challenge stands between you and your summit dreams: Altitude Sickness, medically known as Acute Mountain Sickness (AMS).
This condition can strike unexpectedly as oxygen levels thin beyond 2,400 meters. Whether you’re trekking, meditating in serene mountain sanctuaries, or rafting beneath towering peaks, understanding how to manage altitude change is vital.
What Happens to Your Body at High Elevation?
As you climb, air pressure drops and oxygen becomes scarce. Your body works harder to function, and without proper adjustment time, it may respond negatively — even for seasoned trekkers.
Recognizing the Red Flags: Symptoms of AMS
AMS doesn't wait for an invitation. Symptoms may appear within hours of reaching high altitudes, and they vary in intensity:
- Throbbing headaches
- Queasiness and vomiting
- Lightheadedness or confusion
- Loss of appetite and energy
- Trouble sleeping
- Labored breathing
If ignored, mild AMS may worsen into:
- HAPE: fluid in the lungs
- HACE: swelling in the brain
Both conditions can be fatal without immediate medical response.
Preventing Altitude Sickness: Steps to Stay Ahead
At Adventure Hub Nepal, our itineraries are carefully designed to minimize altitude risks. But the following personal strategies are key:
Adapt Slowly
Avoid jumping too high, too fast. Pause for a night or two at mid-elevation points to let your body adapt.
Drink Generously
Dry mountain air dehydrates you quickly. Keep a steady intake of safe, clean water throughout the day.
Avoid Substances That Interfere
Alcohol, tobacco, and sleep medications can reduce breathing efficiency and delay acclimatization. Skip them until you're back down.
Take It Easy
Pace yourself. Don’t rush — your energy is best preserved with slow, consistent movement.
Eat for Energy
Complex carbohydrates and light, nourishing meals help your metabolism adjust smoothly to altitude changes.
What to Do If Symptoms Strike
If you or someone in your group begins to show signs of AMS, act swiftly:
1. Go Down
The most effective treatment is immediate descent. Even a few hundred meters can make a dramatic difference.
2. Use Supplemental Oxygen
Portable oxygen cylinders can provide short-term relief while stabilizing the person until a descent is possible.
3. Hyperbaric Therapy (Gamow Bag)
These portable pressure chambers simulate a lower elevation, helping to reduce symptoms until further action is possible.
4. Take Altitude Medication
Acetazolamide (Diamox) may be prescribed before or during your ascent to help your body adapt. Always consult a medical professional before using it.
Four Non-Negotiable Altitude Safety Rules
1. Acknowledge early symptoms — never dismiss them.
2. Stop climbing if symptoms begin — acclimatize before continuing.
3. Descend without delay if signs worsen.
4. Stay with your group — ensure no one is left behind, especially when unwell.

The Himalayas demand respect — not just for their size and beauty, but for the challenges they present. At Adventure Hub Nepal, we equip our trekkers with knowledge, expert guidance, and support every step of the way.
