Cusco is located at 3,400 meters (11,150 ft) above sea level, and many travelers experience symptoms related to altitude after arriving.

Altitude sickness is common among visitors who arrive quickly from lower elevations and may affect travelers during their stay in Cusco or while visiting other high-altitude destinations in the Andes.

Early medical evaluation can help determine whether symptoms are part of normal acclimatization or signs of a more serious altitude-related condition.

What is altitude sickness?

Altitude sickness occurs when the body has difficulty adapting to lower oxygen levels at high altitude.

Most travelers experience mild symptoms during the first days after arrival in Cusco, especially if they travel directly from sea level.

Symptoms usually improve as the body acclimatizes, but in some cases they may worsen and require medical evaluation.

Common symptoms

• Headache after arriving in Cusco
• Nausea or vomiting
• Loss of appetite
• Fatigue or unusual tiredness
• Dizziness or lightheadedness
• Difficulty sleeping
• Shortness of breath during mild activity

Warning Signs of Severe Altitude Illness

In some cases altitude illness may progress to more serious conditions requiring urgent medical evaluation.

• Shortness of breath at rest
• Persistent cough or chest discomfort
• Severe weakness or inability to walk normally
• Confusion or unusual behavior
• Severe headache that does not improve

These symptoms may indicate more severe altitude-related conditions such as High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE).

What Travelers Should Do

Travelers experiencing mild symptoms may improve with rest, hydration and gradual acclimatization.

However, if symptoms worsen or do not improve, medical evaluation is recommended to determine whether treatment, descent or additional care is necessary.

Early evaluation helps prevent complications related to high altitude.
