These notes apply to our tours to Lo Manthang and Lhasa.
Acute Mountain Sickness (AMS) can affect travellers at high altitude, usually above 3,050m (10,000ft). AMS is caused by reduced oxygen levels and lower air pressure at altitude. The faster you ascend, the more likely you are to experience symptoms.
Common symptoms of mild to moderate AMS include headaches, dizziness, fatigue, nausea, loss of appetite, difficulty sleeping and shortness of breath during exertion. More serious symptoms can include confusion, chest congestion, severe breathing difficulties, loss of coordination and coughing up blood.
Early recognition is important. The most effective treatment is to descend to a lower altitude as quickly and safely as possible. Oxygen may also be used if available. In severe cases, hospital treatment may be required.
We carry oxygen and a Portable Hyperbaric Chamber (PHC), which can simulate lower altitude conditions when immediate descent is not possible. If a Rider develops serious symptoms such as severe breathing problems, confusion or coughing up blood, we will arrange immediate descent and medical assistance.
To help prevent AMS:
- Ascend gradually where possible
- Rest regularly at higher altitudes
- Drink plenty of fluids
- Avoid alcohol
- Eat regular meals high in carbohydrates
- Learn to recognise early symptoms of AMS
We also carry Diamox (Acetazolamide), which may help reduce AMS symptoms on our Tibet and Ladakh routes.
If you have a history of heart, lung or altitude-related medical conditions, please consult your doctor before joining the tour.
