But when we shortly transfer to these elevations, you may develop medical issues, mostly altitude illness,” Dr. Hermann shares. By progressively getting used to excessive elevations—maybe by settling at a base camp for a couple of days earlier than venturing as much as larger factors and peaks—you may scale back your possibilities of feeling sick or out of types.

In response to Dr. Hermann, the most typical signs of altitude illness embrace nausea, vomiting, and headache, that are “usually gentle and normally resolve inside a few days.” Nevertheless, if you happen to expertise extra extreme signs—together with chest tightness, intense problem respiration, and steadiness or coordination points, he advises looking for quick medical consideration.
