Altitude sickness is normally known as acute mountain sickness. This can happen when people rapidly climb up to an altitude of more than 3000 meters. We ensure minimal risk by adding rest to our trekking itineraries. Most people will feel some effects of altitude, some shortness of breath and possibly light headache, this is normal enough. Acute mountain sickness patients are quite different and usually have a serious headache, sickness, and lose awareness. In almost all possible cases there are sufficient warning signs to take action properly. Descending to a lower altitude is usually enough to prevent any further problems.
