Altitude Sickness in Everest

Everest Trekking

Altitude sickness and environment induced Health problems

The powerful mythology has grown up around the monastery at Tengboche as result of the writings of explores & mountaineers, but the Gompa is not as ancient as you might expect. The first Gompa at Tengboche was constructed in 1916 by Lama Gulu, a monk from Khumjung, but the building was destroyed in the earthquake of 1934, which also killed its founder.A second gompa on the site lasted until 1989, when an electrical fire burned the stone and timber structure to the ground. Tengboche was painstakingly reconstructed, opening its doors in 1993. Inside is a 4m high statue of Sakyamuni, backed by an ornate wooden freeze of mythical beasts that was rescued from the fire. In the doorway to the monastery, note the stone with a foot-shaped imprint, allegedly left by Lama Sange Dorje as he flew around the Himalaya in the 17th century.

The monastery is the setting for the famous Mani Rimdu festival in the ninth Tibetan month with whirling masked chaam dances & plenty of eating, drinking & making merry. Visitors are welcome to attend the daily prayer ceremonies at 6am & 3pm, but sit to the right so as not to interrupt the monks as they chant the scriptures. Wearing shoes or shorts, smoking & taking photo are all prohibited inside the monastery.

How to Prevent Altitude Sickness for Trekkers

Drink 5 Liters of Water Per Day
Quite simply, drink a minimum of five liters of water per day, no matter what. This is easier at lower elevations when it’s hot, but becomes more burdensome when temperatures cool off and you perspire less. After a few liters you may feel properly hydrated, but your body is doing extra work with less oxygen and needs the water. Force down five liters per day, without exceptions.

Avoid Dramatic Gains in Elevation
Treks at altitude should avoid big single-day gains in elevation (more than 1,500 vertical feet). A common misconception about trekking at high altitude is that physical condition dictates the body’s ability to fend off altitude sickness. This causes many people who are “in good shape” to ignore the rules of acclimatization, go too high too fast, and have problems. Your itinerary should factor in altitude gains and consequently some hiking days will end early. Embrace the pace, rest your legs, and hydrate.

Climb High, Sleep Low
You will acclimatize better if you expose yourself to higher altitudes but return to a lower altitude to sleep. After setting up camp, scramble up a nearby hill, scope out the scenery, and head back down for a better night’s rest. When you have a rest day, use the opportunity to hike to higher elevations and back down—even a few hundred vertical feet is worth the effort. At higher altitudes—around 10,000 feet and above—this rule becomes even more important as your body is learning to cope with considerably less oxygen.

Eat, Eat, Eat
Your body is doing more work than usual so make sure to stay nourished and full of carbohydrates. For a dependable snack, Nepal has embraced the Snickers bar wholeheartedly and it can be found even in the tiniest villages (and for very cheap). Too much sugar, yes, but full of good things like nuts and chocolate. Do a good deed and buy some for your porters and guide whenever possible.

Listen to Your Body
By following the above rules, you will greatly increase your odds of staying healthy throughout your trek, but everybody reacts differently to altitude so pay close attention to how you feel. Every trek should have rest days built in and you shouldn’t be afraid to use them. Stay hydrated, wear sunscreen, and have layers available for protection from the powerful sun. Avoid alcohol and other substances. Monitor yourself and always communicate any health concerns to your group. An estimated 75% of people feel some affects of altitude, mostly in the form of headaches, nausea, fatigue, and trouble sleeping. These are actually mild manifestations of Acute Mountain Sickness (AMS). Mild AMS should not interfere with normal activity and the symptoms should subside as acclimatization occurs. As long as the symptoms are mild, it’s generally okay to continue hiking up at a moderate rate. If feeling poorly persists or worsens, turn around.

Medications for Altitude Sickness
The only treatment for altitude sickness is descent, but medication can help with the symptoms. Consult a doctor before use. Ibuprofen can be used to treat the symptoms of mild altitude sickness such as headaches and nausea.
Diamox (Acetazolamide) is a respiratory stimulant that helps the body metabolize more oxygen, especially at night, thereby accelerating the process of acclimatization. Diamox can be used as a prophylactic, particularly by those making unavoidably large ascents.

Severe Problems
In severe cases altitude sickness can be truly life-threatening. If a trekker ever gets an unusual or severe headache, or feels unusually short of breath, they should immediately descend 2,000 feet (600 meters), no matter the time of day. High Altitude Pulmonary Edema (HAPE), excess fluid in the lungs, and High Altitude Cerebral Edema (HACE), swelling of the brain, are rare but life threatening conditions that require immediate descent and medical attention.
