What might indicate that a climber is experiencing altitude sickness?

• A. Excessive enthusiasm
• B. Giddiness
• C. Fatigue and dizziness
• D. Improved vision

Answer: (C)

Altitude sickness, also known as acute mountain sickness (AMS), can manifest through several symptoms as the body struggles to acclimatize to reduced oxygen levels at higher elevations. The presence of fatigue and dizziness is particularly important as these are common physical signs that the body is not functioning optimally in the altitude conditions. When ascending to higher altitudes, changes in environmental conditions can lead to inadequate oxygen delivery to tissues, resulting in feelings of exhaustion and light-headedness. These signs should prompt the climber to assess their condition and possibly take action, such as resting, hydrating, or descending to a lower altitude where oxygen levels are more favorable. Other symptoms like excessive enthusiasm or giddiness may not indicate altitude sickness and could even suggest a surprising reaction to the thrill of climbing rather than a physiological response to high elevation. Improved vision is not a symptom associated with altitude sickness and may incorrectly suggest a positive change in condition. Recognizing fatigue and dizziness as signs of altitude sickness is crucial in ensuring climbers maintain their safety and health when navigating mountainous environments.
