Tha atmospheric pressure lowers as you go higher in the mountains, while your internal pressure stays constant.
Like a ballon filled with gas, the tension of the skin of the ballon is such that it balances the internal with the external pressure.
When you reduce the outside pressure, the ballon expands under the internal pressure, now greater than the external.
It is the same for your body. Exposed to lower pressure in altitude, your blood vessels have an internal pressure higher than the outside atmospheric pressure: the capillaries (smaller blood vessels) break under the strain.
Usually, after a while your internal pressure will lower as well to the same level as the external pressure, and all will be ok again!

The reduction in air pressure makes it easier for vessels to rupture, especially those of the nose, that tend to be closer to the surface of the skin. As there is less air, the internal pressure of the body has less force acting against it, and you literally spring a leak.

the change in air pressure can cause nose bleeds, ear popping and sometimes gas. this is normal. it's the body adjusting to the different pressure.

The altitude is the main problem

Banging their nose against rocks. They should be more careful. Daft buggers.
