Prevention:

Keys to preventing acute mountain sickness include:

• Climb the mountain gradually
• Stop for a day or two of rest for every 2,000 feet (600 meters) above 8,000 feet (2,400 meters)
• Sleep at a lower altitude when possible
• Learn how to recognize early symptoms of mountain sickness

If you are traveling above 9,840 feet (3,000 meters), you should carry enough oxygen for several days.

If you plan on quickly climbing to a high altitude, ask your doctor about a medication called acetazolamide (Diamox). This drug helps your body get used to higher altitudes more quickly, and reduces minor symptoms. It should be taken the day before you climb, and then for the next 1 to 2 days.

If you are at risk for anemia, ask your doctor if an iron supplement is right for you. Anemia lowers the amount of oxygen in your blood.

While climbing:

• Drink plenty of fluids
• Avoid alcohol
• Eat regular meals, high in carbohydrates

You should avoid high altitudes if you have heart or lung disease.
