Frequently Asked Question

AMS is very common for most tourists when they first arrive on the high plateau. It can affect individuals differently based on their own health situation. All of our itineraries are designed with altitude sickness in mind. We suggest our clients drink plenty of water, especially for the first few days, and do as little physical exertion as possible upon arrival. Most people need 2 to 3 days to acclimatize in Lhasa.

It is very important to consult your doctor before you leave your home country. Useful medications include: cold and flu tablets, throat lozenges, nasal decongestants, and Aspirin. Diamox is good for the altitude sickness, but remember to ask your local doctor for instructions and suggestions. Don’t forget to drink plenty of water after you take the Diamox,to prevent serious dehydration.

Getting adequate rest and administering oxygen can help alleviate some of the symptoms of altitude sickness. The main form of treatment for all kinds of mountain sickness is to descend to a lower altitude as rapidly and safely as possible. Extra oxygen should be given if available. If a patient does not show any sign of improvement after 3 to 4 hours, he/she should go to a hospital for treatment.

Visitors with a severe cold, a high fever, acute or chronic pulmonary diseases, severe cardiovascular diseases, women with an advanced pregnancy and children under three years of age should avoid traveling to regions with a high altitude

To prevent the occurrence of altitude sickness, visitors should have a proper rest and avoid strenuous activities days before you go to Tibet. After getting off the plane, you should try not to carry heavy things or run and avoid outdoor activities. NifedipinumNuodikang Capsules and Suoluomabao Capsules (known as Hongjingtian Capsules in Chinese) may help some people prevent the occurrence of altitude sickness when they are taken three days before arrival to a highland. Note: Acetazolamide (Diamox) is a drug used to stimulate breathing and reduce mild symptoms of mountain sickness. This drug can cause increased urination, so when taking this medication, make sure you drink plenty of fluids and do not drink alcohol; if you don’t drink enough water, it may result in serious dehydration, which can worsen AMS.

Altitude sickness, also known as Acute Mountain Sickness (AMS), is a pathological effect of high altitude on humans, caused by acute exposure to low air pressure (usually outdoors at high altitudes). It usually occurs around 3,000 meters above sea level. Cold temperatures, high fever and extreme fatigue can all lead to altitude sickness.

The rates of acute altitude sickness 3,000 m, 3,700 m, 3,900 m, 4,520 m and 5,300m above sea level are 40 percent, 57.3 percent, 63.8 percent, 89.24 percent and 100 percent, according to a survey Although these values are typical, experts point out that the human body is very adaptable and has a magical capability for acclimation. As breakthroughs have been made in determining the cause of altitude sickness and in the treatment, the cure rate of the two most common forms of acute altitude sickness — high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE) — has reached 99%.
