How is altitude sickness diagnosed?

If you get a headache and at least one other symptom with 24 to 48 hours of moving to a higher elevation, it’s most likely altitude sickness. If you’re climbing, a more experienced climber may recognize symptoms of altitude sickness and guide you to get help.

If you have severe altitude sickness, a healthcare provider will ask about your symptoms, activities and location. The provider may perform a physical exam, including listening to your chest.
