Question 1

What is altitude sickness and what causes it?

Accepted Answer

Altitude sickness, also known as acute mountain sickness (AMS), occurs when you ascend to high elevations too quickly. The body struggles to adjust to reduced oxygen levels at altitudes above 8,000 feet, leading to symptoms like headache, nausea, and fatigue.

Question 2

What are the symptoms of altitude sickness?

Accepted Answer

Common symptoms include headache, dizziness, nausea, shortness of breath, fatigue, and trouble sleeping. In more severe cases, symptoms can progress to confusion, difficulty walking, and chest tightness, which require immediate medical attention.

Question 3

At what altitude do you start feeling sick?

Accepted Answer

Most people begin to experience mild altitude sickness at elevations above 8,000 feet. The risk increases with rapid ascent and higher altitudes, especially above 10,000–12,000 feet.

Question 4

How long does altitude sickness usually last?

Accepted Answer

Mild altitude sickness typically resolves within 1 to 3 days as the body acclimates. Rest, hydration, and avoiding further ascent can help speed recovery. Severe symptoms may require descent and medical care.

Question 5

What is the fastest way to recover from altitude sickness?

Accepted Answer

The quickest recovery often involves descending to a lower altitude. Staying well hydrated, resting, avoiding alcohol, and using supplemental oxygen or medication (such as acetazolamide) may also ease symptoms.

Question 6

What is the best over-the-counter medicine for altitude sickness?

Accepted Answer

Over-the-counter options like ibuprofen can help relieve headaches and discomfort. However, acetazolamide (Diamox), a prescription drug, is commonly recommended for prevention and treatment under a doctor’s guidance.

Question 7

How is altitude sickness treated medically?

Accepted Answer

Medical treatment may include oxygen therapy, acetazolamide, or dexamethasone for more severe symptoms. Descent to lower elevation is the most effective solution in moderate to severe cases.

Question 8

Who is more prone to altitude sickness?

Accepted Answer

Anyone can develop altitude sickness, but those with a history of the condition, those ascending rapidly, and individuals who live at lower elevations are at greater risk.

Question 9

Can altitude sickness become dangerous or life-threatening?

Accepted Answer

Yes, in rare cases, altitude sickness can progress to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), both of which are medical emergencies and require immediate care.

Question 10

How can I prevent altitude sickness when traveling to high elevations?

Accepted Answer

Gradual ascent, staying hydrated, limiting physical exertion during the first 24–48 hours, and possibly taking acetazolamide before travel can help reduce the risk. Avoiding alcohol and sleeping at lower elevations also helps.
