Tibet is totally unique. If this is your first trip to the Roof of the World, chances are that you will find the climate different from anything you have ever experienced. The Tibetan Plateau is not only at high altitude (most areas are 3,500 metres (13,000 feet) or higher), it is also extremely dry.
The high altitude, lack of moisture in the air, intense sun and cold wind combine to present you with a real challenge.So it's important to know what to expect, especially what to expect from your body as it adjusts to a different environment and altitude.
Although this website provides an overview of altitude sickness from a lay person's perspective (and some information about medical facilities in Tibet), it is absolutely vital that you discuss both the prevention and treatment of altitude sickness with your physician, arrange appropriate medication such as acetazolamide (diamox) etc., at least a month before you plan to travel. You may also need to take the required vaccinations, as your doctor advises.
Travel insurance that includes emergency medical evacuation by air is highly recommended.
