Altitude Sickness: What You Need to Know
Types of Altitude Sickness:
Acute Mountain Sickness (AMS):
Symptoms: Headache, nausea, dizziness, fatigue, shortness of breath, loss of appetite, and difficulty sleeping.
High Altitude Cerebral Edema (HACE):
Symptoms: Severe headache, loss of coordination, confusion, hallucinations, and coma. It is life-threatening.
High Altitude Pulmonary Edema (HAPE):
Symptoms: Shortness of breath at rest, cough, weakness, chest tightness, and blue/gray lips or fingernails. It is life-threatening.
Preventive Measures
Gradual Ascent:
Acclimatization: Take your time to acclimatize. The typical itinerary includes rest days at certain points (e.g., at Ghorepani or Chomrong).
Slow Pace: Ascend slowly to give your body time to adjust to the altitude.
Hydration:
Drink Water: Keep yourself well-hydrated by drinking plenty of fluids (3-4 liters a day).
Avoid Alcohol and Caffeine: These can dehydrate your body and exacerbate symptoms.
Diet:
Eat Carbohydrates: Eating a high-carb diet can help you maintain energy levels and combat altitude sickness.
Medication:
Diamox (Acetazolamide): Consult with a healthcare professional about taking Diamox to help prevent AMS. Start the medication a day before you start ascending.
Recognize Symptoms Early:
Self-Monitor: Be aware of how you feel and communicate any symptoms to your guide or trekking companions.
Immediate Action: If symptoms of AMS appear, do not ascend further. If symptoms worsen, descend to a lower altitude immediately.
Emergency Measures
Descent: The most effective treatment for severe altitude sickness is to descend to a lower altitude as quickly as possible.
Oxygen: Carry supplemental oxygen if available, and know how to use it in an emergency.
Medical Assistance: Seek medical help if symptoms are severe. Helicopter evacuations are available in emergencies but are expensive. This itinerary includes a gradual ascent and rest days, which help with acclimatization.
By following these preventive measures and being aware of the symptoms and treatment of altitude sickness, you can minimize the risks and have a safe and enjoyable trek to Annapurna Base Camp.
