May precede AMS via fluid retention; hypothesis-generating for hormonal targets, needs prospective confirmation before practice change.
Does exercise at high altitude induce a greater rise in aldosterone and vasopressin in mountaineers who develop acute mountain sickness compared to those who do not?
An enhanced exercise-induced rise in aldosterone and vasopressin at high altitude precedes and may contribute to the fluid retention associated with acute mountain sickness.
Bärtsch et al. (1991) studied this question.
