Whether you are trekking to the incredible heights of Baltoro glacier or K2 base camp, you won’t just test yourself physically but the solidifying cold and most importantly, the altitude.
As you go up, the air gets thinner and the outcome is reduced oxygen availability. Thus, blood oxygen levels drop and the body is famished of oxygen for exercise and crucial functions.

Your mind detects that you have less oxygen in your blood than you are used to and it restricts the power of any activity you do, by sending messages through the central nervous system to back off muscle constrictions because your brain is voracious for oxygen, and should keep up a steady supply.

Mellow symptoms are nausea and headache and can be treated with your standard painkillers.
