Symptoms of Acute Mountain Sickness (AMS): * Headaches * The most common early symptom * Often localized and may worsen with exertion * Nausea and Vomiting * Can be mild to severe * Often accompanied by loss of appetite * Fatigue or Weakness * Unexplained lethargy * General lack of energy, even during basic activities * Dizziness or Lightheadedness * Feelings of vertigo or disorientation * May also experience balance issues * Insomnia * Difficulty sleeping at higher altitudes * Shortness of breath during the night can exacerbate the problem * Swelling (Edema) * Notable swelling of extremities (hands and feet) * In severe cases, may experience swelling of the face (AMS can progress to HACE) * Increased Heart Rate * Palpitations or rapid heartbeat * The body’s response to low oxygen levels

Prevention Strategies for AMS: * Acclimatization * Gradually ascend to higher altitudes * Take rest days every 1,000 feet gained * Hydration * Drink plenty of fluids to stay hydrated * Avoid alcohol and caffeine, as they can cause dehydration * Diet * Eat easily digestible, high-carbohydrate meals * Avoid heavy meals that can exacerbate nausea * Medications * Consider using acetazolamide (Diamox) to aid in acclimatization * Consult with a healthcare provider before climbing about taking preventive medication * Pacing * Climb slowly and listen to your body * Know your limits and stop if symptoms develop * Oxygen Supplementation * In extreme cases of high altitude, consider portable supplemental oxygen (consult guides) * Use if symptoms worsen or to aid in recovery during acclimatization * Avoid Strenuous Activity * Engage in light activity during initial acclimatization * Reserve challenging climbs for later in the ascend
