High-Altitude Illness, which includes Acute Mountain Sickness (AMS), High Altitude Pulmonary Edema (HAPE), and High Altitude Cerebral Edema (HACE), is a condition that can affect those who travel to high altitudes, typically above 8,000 feet (2,500 meters). Here are the common symptoms:
At high altitudes, the air pressure is lower, which means there are fewer oxygen molecules in the same volume of air compared to sea level. The body responds to this lower oxygen availability by breathing faster and deeper and by increasing heart rate to deliver more oxygen to the tissues.
In some individuals, however, these responses are not sufficient or occur too slowly, leading to lower than normal levels of oxygen in the blood. This lack of oxygen can cause a variety of symptoms and, in severe cases, can lead to fluid leakage from blood vessels, causing swelling in either the lungs (HAPE) or the brain (HACE).
Prevention is the best approach to high-altitude illness. Here are some strategies to manage and prevent the symptoms:
Remember, high-altitude illness can be a serious condition that can become life-threatening without appropriate treatment. Always prioritize safety, descend immediately if severe symptoms appear, and seek medical attention.
This handout provides an overview of high altitude illness and how to manage it. Always consult with a healthcare provider for accurate diagnosis, treatment, and support for your condition.
