Preventing Altitude Sickness in Bolivia

Prevent altitude sickness by spending your first 48 hours in a lower-altitude city like Santa Cruz, then ascending gradually. Stay hydrated with 3 liters of water daily, avoid alcohol, and consult your doctor about starting acetazolamide (Diamox) 24 hours before your ascent.

  1. Plan a gradual ascent. Do not fly directly from sea level to La Paz (3,640m/11,942ft). Start your trip in Santa Cruz (400m/1,312ft) or Sucre (2,810m/9,219ft) to allow your body to acclimatize for at least 2 full days before heading to higher altitudes.
  2. Use medical prophylaxis. Ask your doctor for a prescription of acetazolamide (Diamox). Start taking it 24 hours before you travel to high altitudes and continue for 48 hours after arriving at your highest destination.
  3. Manage your hydration and diet. Drink at least 3 liters of water every day. Alcohol and heavy meals strain your heart and digestion; avoid both for the first 3 days of your trip.
  4. Respect the 'Coca' tradition. Drink coca leaf tea (mate de coca) or chew the leaves as the locals do. It is a mild stimulant that helps alleviate mild symptoms like headaches and nausea. Do not consume it in excess as it can cause insomnia.
  5. Monitor for danger signs. If you experience severe confusion, inability to walk in a straight line, or persistent coughing, descend immediately. These are signs of HAPE or HACE, which are medical emergencies.
Is it normal to have trouble sleeping?
Yes. Periodic breathing (waking up gasping for air) is very common at high altitudes. It usually subsides after 3-4 nights.
How long does it take to fully acclimatize?
Most people feel significant improvement after 3 to 5 days, but full physiological adjustment can take up to 2 weeks.
