What Is Altitude Sickness in Peru
Altitude sickness, called soroche in Peru, is a temporary condition that occurs when a person ascends abruptly to high altitudes. It typically occurs 2,800 meters (8,000 feet) above sea level, where the air is thinner, and there is less oxygen. It occurs due to rapid ascent without proper acclimatization, and it should not be confused with general fatigue or illness.
In most cases, the condition is mild and temporary and resolves over time with acclimatization. It is important not to confuse it with altitude pulmonary edema and altitude cerebral edema, which are more serious forms of the sickness. The key difference is that both of those conditions require immediate descent, while soroche only requires rest.
Why Altitude Sickness Is Common in Peru
Altitude sickness, known locally as soroche, is common among travelers in Peru due to insufficient acclimatization. Most visitors arrive at high elevation places (various tourist destinations) from sea level without sufficient prior rest. Physically, this is because at higher altitudes, oxygen levels are lower, reducing the amount that reaches the lungs and blood. Furthermore, it can affect anyone regardless of physical condition, age, or weight; therefore, it is common among visitors.
Common Symptoms of Altitude Sickness in Peru
While symptoms vary from person to person, some are more common than others. However, certain symptoms are common with underlying medical conditions that make them more susceptible. Some of these include heart disease, lung disease, diabetes, and asthma, among others. Nevertheless, some of the most common symptoms among tourists are the following:
- Difficulty breathing
- Sleep disturbances
- Loss of appetite
- Digestive discomfort
- Headache
- Nausea
- Vomiting
- Fatigue
- Dizziness
How to Prevent Altitude Sickness When Traveling in Peru
The best way to avoid altitude sickness is to gradually ascend to allow your body to adapt properly. This helps the body acclimatize gradually, thus avoiding the symptoms of this condition. This recommendation also applies to those trekking in Peru, as most adventure tours also take place at high elevations.
Acclimatization Tips for Cusco and Other High-Altitude Destinations
Visitors who don’t have enough time or haven’t planned properly should review some additional tips. There are many ways to alleviate the soroche symptoms. From modern tips to natural remedies, travelers will find many ways to feel better. Here are some of the most popular:
Hydration and Nutrition
While loss of appetite is one of the main symptoms, eating light meals and carbohydrates is recommended. Avoiding heavy meals and saturated fats will be essential during the first few days. Likewise, staying hydrated can help significantly; ideally, drink at least 2–3 liters of water per day. As time goes on, visitors can try other foods and drinks.
Natural Remedies
One of the most popular Cusco travel tips is to drink coca tea or chew coca leaves. The coca leaf has properties that help relieve fatigue and headaches. Historically, this traditional remedy has been used to help the body cope with high-altitude conditions. Other natural remedies include medicinal plants such as muña, an ingredient used in teas for stomach ailments.
Avoid Excessive Consumption
It is essential to avoid alcohol and tobacco, as they worsen symptoms and dehydrate the body. This precaution should be taken for at least the first 48 hours after arriving at higher elevations. If travelers have planned high-altitude treks, even greater care is needed due to the increased physical exertion.
Medications
Other options include taking medications after consulting a doctor. Some specialists recommend taking pills during your travel to Cusco or other high-altitude places. These medications must be prescribed by certified physicians based on the individual’s medical condition and after evaluating potential side effects. Some medications include Acetazolamide (Diamox), Dexamethasone, Nifedipine, and Ibuprofen, among others.
Rest and Limit Physical Activity
Travelers experiencing symptoms should rest and limit physical activity during their first few days of exploring. If possible, it’s highly recommended to rest for at least the first 24 hours after arriving at your high-altitude destination. Other excellent options include light activities such as leisurely walks.
Best Remedies for Altitude Sickness (Natural & Medical)
Visitors still unsure whether to choose one remedy over another should consider the benefits and their specific needs. The traveler’s circumstances and available time will also play a significant role. While natural remedies are the most popular among tourists, many others opt for medical treatments. Here is a comparison table of both to help you make an informed decision.
| Natural Remedies | Medical Remedies | |
| Examples of remedies | Hydration, ginger tea, coca leaves/tea, rest, gradual ascent | Acetazolamide (Diamox), ibuprofen, oxygen therapy, and dexamethasone |
| Ease of access | Usually easy to find (water, herbs, rest) | Requires prescription or medical assistance in many cases |
| Speed of effect | Slower, gradual relief | Faster, more immediate symptom relief |
| Cost | Low cost or free | Can be more expensive depending on the medication or treatment |
| Side effects | Minimal or none (generally safe) | Possible side effects (tingling, nausea, allergic reactions, etc.) |
| Scientific support | Limited or mixed evidence | Strong scientific and clinical evidence |
| Need for supervision | No professional supervision needed | Often requires medical advice or supervision |
| Best for | Mild symptoms and prevention | Moderate to severe symptoms or high-risk individuals |
High-Altitude Destinations in Peru You Should Know
The destination’s elevation above sea level is also one of the most important factors to consider. Visitors are more likely to experience altitude sickness in high-altitude areas than in lower-altitude destinations like the Amazon rainforest or coastal cities. Therefore, visitors should exercise particular caution when traveling to Andean destinations. Here is a summary of the main tourist destinations with considerable elevations:

- Machu Picchu elevation: 2,430 meters (7,972 feet)
- Ollantaytambo elevation: 2,792 meters (9,160 feet)
- Cusco elevation: 3,399 meters (11,152 feet)
- Lake Titicaca elevation: 3,812 meters (12,507 feet)
- Puno elevation: 3,830 meters (12,556 feet)
- Inca Trail maximum elevation: 4,200 meters (13,800 feet)
- Rainbow Mountain elevation: 5,200 meters (17,060 feet)
- Cordillera Blanca elevation: 6,768 meters (22,205 feet)
When to Seek Medical Help for Altitude Sickness
Tourists experiencing altitude sickness symptoms that worsen over time and do not improve with rest should seek medical help. Some symptoms can be signs of more serious complications, so it’s important to pay attention. Likewise, more serious complications can also be warning signs to consult a specialist. These symptoms include extreme difficulty breathing, persistent cough, mental confusion, severe headache, and severe vomiting, among others.
