Survival Guide: Dealing with Altitude Sickness

Bolivia is home to the world’s highest city (La Paz at 3600 meters above sea level), the world’s highest town (Potosi at 4090 meters) and the worlds highest navigable lake (Lake Titicaca at 3827 meters) – pretty much everything is high up in Bolivia. All this high altitude can be difficult for many travelers and can pose a serious health risk if the correct precautions aren’t taken.

Altitude sickness, also known as acute mountain sickness (AMS), typically occurs above 2,400 meters and is caused by exposure to decreased oxygen at high altitudes. It often causes tiredness and nausea but can also cause swelling of the face and hands, difficulty sleeping, and severe headaches.

During our Bolivia Salt Flats Tour from Tupiza to Uyuni, my travel partner was hit with a bad spell of altitude sickness. Neither of us had previously experienced high altitude and weren’t sure how it would effect us. I took acetazolamide (altitude medication) but due to a sulfa allergy, my friend was unable to take the meds.

The tour began in Tupiza at around 2,990m and ascended to 4,660m near San Antonio de Lipez on the first day. Within hours her energy was drained, she had a massive headache, became very dizzy and began vomiting.

I attributed her AMS to our ascending too fast, and although her symptoms went away after about 3 days, it would have made a much more enjoyable trip for her if we had taken better precautions to prevent it. Taking coca leaves in tea or with sweets seemed to help calm her stomach enough to give her a good nights sleep and she began to recover soon after and was finally able to enjoy the beautiful Salar.

Here are some tips in dealing with AMS:

  • Rest for a few day after arriving to allow your body to adjust
  • Every third day, spend at least two nights at the same elevation
  • Go slowly – high altitudes make even normal activities much harder, take a break if you are out of breath or feel pins and needles in your extremities
  • Don’t climb more than 3,000 feet per day (1,000 feet per day if at 12,000 feet or above)
  • Drink lots of water but eat smaller, more frequent amounts. Your body has a harder time processing in low oxygen. Avoid alcohol
  • Do not take sleeping pills or medications which mask symptoms or could aggravate your condition
  • Sleep at a lower altitude, blood oxygen level may fall even lower when sleeping
  • Slow down breathing to help relieve headache and dizziness
