Quick Answer
Dangerous Signs Of Altitude Sickness To Watch For: Altitude sickness, such as acute mountain sickness (AMS), can be a serious issue at high elevations, especially in Colorado's notorious 14ers. Watch for symptoms like headaches, dizziness, nausea, and fatigue, which can progress to life-threatening conditions if ignored. Recognizing these signs early is crucial for safe descent.
Recognizing the Symptoms
At elevations above 8,000 feet, even mild symptoms like headaches and fatigue can signal the onset of altitude sickness. Be aware of the “Lake Louise Score,” a simple assessment tool used to identify AMS. To use it, rate the severity of headaches, dizziness, fatigue, and nausea on a scale of 0 to 3, then add the scores. A total of 4 or higher indicates potential AMS. If you experience any of these symptoms, rest and hydrate, and consider descending to a lower elevation.
Acclimatization Techniques
To minimize the risk of altitude sickness, acclimatize to higher elevations gradually. Plan to ascend no more than 1,000 feet per day, and rest for at least a day at 8,000 to 12,000 feet before pushing higher. This allows your body to adapt to the lower oxygen levels. Additionally, drink plenty of water and electrolyte-rich beverages to stay hydrated, and consume high-altitude-specific foods like soups and teas to help your body acclimate.
Descent and Prevention
If you or a companion shows signs of altitude sickness, descend immediately to a lower elevation. Aim for a decrease of 1,000 to 2,000 feet. If symptoms worsen, seek medical attention. To prevent altitude sickness, consider consulting a doctor about a prescription medication called dexamethasone, which can help alleviate symptoms. Additionally, use oxygen supplements, and avoid strenuous activities, especially during the first 24 hours at high elevation.
