Should I take Diamox if I've never had altitude sickness before?

Consider it if you're flying directly to Quito from sea level, especially for planned activities above 12,000 feet. Many people tolerate Quito's altitude without medication, but it provides insurance for higher elevations.

Can I exercise normally at altitude in Ecuador?

Reduce exercise intensity by 30-50% your first week. Your heart rate will be higher and you'll fatigue faster. Light walking around Quito is fine, but avoid strenuous hikes until you've acclimatized for 2-3 days.

What if I get sick on a mountain with no way down?

This is why guides and proper planning matter. Most Ecuador mountain tours include emergency descent protocols. Carry a satellite communicator for remote areas. Never attempt technical climbs without experienced guides and evacuation plans.

Are some people more susceptible to altitude sickness?

Yes. Age, fitness level, and genetics all play roles, but there's no reliable predictor. Athletes can be just as affected as sedentary people. Previous tolerance doesn't guarantee future tolerance.

How long does acclimatization last?

You'll lose acclimatization within 2-3 weeks of returning to sea level. Each return trip to altitude requires the same careful ascent process, though some people find subsequent visits slightly easier.

How to Handle Altitude Sickness in Ecuador's Andes

Ascend gradually, drink 3-4 liters of water daily, and recognize symptoms early. Quito sits at 9,350 feet, so arrive 2-3 days before heading higher. If symptoms worsen below 8,000 feet, descend immediately and seek medical help.

Arrive in Quito 2-3 days early. Don't fly directly to high altitude destinations. Spend 48-72 hours in Quito (9,350 feet) before attempting Cotopaxi, Chimborazo, or other high-altitude activities. Your body needs time to produce more red blood cells.
Climb high, sleep low. On day hikes above 12,000 feet, return to lower elevations to sleep. If camping above 10,000 feet, ascend no more than 1,600 feet per day. Sleep at the lowest practical elevation each night.
Drink 3-4 liters of water daily. High altitude increases water loss through breathing and urination. Clear, frequent urination means you're hydrated. Dark yellow urine is a warning sign. Avoid alcohol your first 48 hours at altitude.
Recognize early symptoms. Headache, nausea, fatigue, and dizziness are normal above 8,000 feet. Loss of appetite and difficulty sleeping are common. These should improve within 24-48 hours as you acclimatize.
Watch for danger signs. Severe headache, vomiting, confusion, loss of coordination, or difficulty breathing require immediate descent. Don't ignore worsening symptoms. High altitude cerebral edema (HACE) and pulmonary edema (HAPE) can be fatal.
Descend if symptoms worsen. If symptoms persist after 2 days or worsen at any time, descend immediately. Even 1,500-3,000 feet down can provide relief. Don't wait to 'see if it gets better' - altitude sickness can progress rapidly.
Consider medication. Acetazolamide (Diamox) 125-250mg twice daily starting 1-2 days before ascent can help. Consult a doctor before travel. Ibuprofen helps with headaches. Avoid sleeping pills - they can suppress breathing.
