What is High Altitude Illness?
Are you planning a trip to the mountains or a high-altitude destination? 🏔️ If so, it’s essential to understand the risks of high altitude illness. Also known as altitude sickness, high altitude illness occurs when your body cannot adapt quickly enough to the lower air pressure and lower oxygen levels at high elevations. This can lead to a range of symptoms, from mild to life-threatening.
What happens at high altitude? At high elevations, the air pressure is lower, and the oxygen levels are decreased. This means that your body has to work harder to breathe in enough oxygen. If you ascend too quickly, your body may not be able to adapt fast enough, leading to altitude sickness.
High altitude illness can affect anyone, regardless of age, fitness level, or health status. However, certain individuals are more at risk, including:
- People who live at low elevations and travel to high-altitude areas
- Those who have pre-existing medical conditions, such as heart or lung disease
- Individuals who are obese or physically inactive
- Pregnant women
If you’re planning a trip to a high-altitude destination, it’s crucial to understand the risks and take necessary precautions to prevent altitude sickness. In the next section, we’ll explore the different types of high altitude illness.

- Seizures
- Coma
HACE is a life-threatening condition that requires immediate medical attention. If you or someone in your group experiences any of these symptoms, descend to a lower elevation immediately and seek medical help.
High-Altitude Pulmonary Edema (HAPE)
HAPE is a severe and potentially life-threatening form of high altitude illness that affects the lungs. Symptoms can include:
- Shortness of breath
- Chest tightness
- Coughing up pink, frothy mucus
- Blue-tinged lips and fingers
HAPE requires immediate medical attention and descent to a lower elevation. If left untreated, HAPE can lead to respiratory failure and death.
