Elevation Sickness Prevention

Elevation sickness prevention uses gradual ascent, hydration, and early descent when headache or nausea appear at altitude. Medications require clinician guidance for high-risk trips.

Elevation sickness prevention limits rapid exposure to altitude without recovery—headache, nausea, and fatigue signal acute mountain sickness. Ascend gradually, avoid alcohol and sedatives early on, and descend if symptoms progress.

Dexamethasone and acetazolamide are clinician tools for high-risk trips, not casual shortcuts.

Common questions

  • Who gets altitude sickness?

    Anyone can develop AMS regardless of fitness. Prior tolerance helps but is not guaranteed—rate of ascent and sleeping altitude matter most.
