Altitude sickness — known locally as soroche — is common for travelers to Bolivia’s high-altitude destinations like La Paz, Uyuni, and Potosí. Symptoms are usually mild (headache, fatigue, shortness of breath) and improve within a few days as your body adjusts, but taking it slow on arrival makes a real difference in how you feel.
What Is Altitude Sickness?
Much of Bolivia is at high altitude – cities like La Paz (3,650 m / 11,975 ft) and Potosí (4,067 m / 13,343 ft) are among the highest in the world. Visitors may experience sorojchi (altitude sickness).
Symptoms to Watch For
Mild symptoms are common and usually include headache, fatigue, shortness of breath, nausea, or difficulty sleeping — these typically improve within a few days. Seek medical help immediately if you experience confusion, severe shortness of breath, loss of coordination, or symptoms that worsen even at rest, as these can signal a more serious condition.
Prevention Tips
- Take it slow: Allow your body time to acclimatize, especially if flying directly into high-altitude cities.
- Stay hydrated: Drink plenty of water and avoid excessive alcohol or heavy meals on your first days.
- Coca tea: A traditional remedy many travelers find comforting, though it isn’t a proven substitute for acclimatizing carefully.
- Plan smart: If possible, start your journey in lower-altitude areas (like Santa Cruz or Sucre) before moving higher.
Medication & Remedies
Some travelers use preventive medication for altitude sickness — talk to your doctor before your trip to see if it’s right for you. Over-the-counter “soroche pills” (a mix of aspirin and caffeine) and supplemental oxygen are also available at pharmacies throughout La Paz for symptom relief.
⚠️ Verify this: Altitude sickness affects everyone differently, and this page isn’t a substitute for medical advice. If you have heart, lung, or other health conditions, or plan to use preventive medication, talk to a doctor before your trip.
Where This Matters Most
Altitude is most relevant in La Paz, Uyuni, and Potosí — all high enough that most travelers notice some effect. If you’d rather ease into it, consider starting your trip in Santa Cruz or Sucre, both at lower elevations, before heading up to the Altiplano.
