Quick Answer
At high elevations, such as those found on Colorado's 14ers, altitude sickness symptoms can manifest as headaches, fatigue, nausea, and shortness of breath, typically between 8,000 and 11,000 feet, and can be severe above 12,000 feet.
Understanding Altitude Sickness
Altitude sickness, also known as acute mountain sickness (AMS), is a condition that occurs when the body cannot adapt quickly enough to high elevations. The most common symptoms are headaches, fatigue, nausea, and shortness of breath, which can range from mild to severe. In Colorado, the risk of altitude sickness increases above 8,000 feet, and severe symptoms can occur above 12,000 feet.
Acclimatization Techniques
To minimize the risk of altitude sickness, it’s essential to acclimatize your body to the high elevation. Start by ascending at a gradual pace, allowing your body to adjust to the increased elevation. Aim to ascend no more than 1,000 feet per day, and spend an extra night at each camp to allow your body to acclimatize. Drink plenty of water and take breaks to rest and hydrate.
Descent and Prevention
If you experience symptoms of altitude sickness, descend to a lower elevation immediately. For every 1,000 feet of elevation, descend 500-1,000 feet to alleviate symptoms. To prevent altitude sickness, use Diamox (acetazolamide) as directed, and consider taking a course of Diamox before ascending to high elevations. Always consult with a medical professional before taking any medication.
