Altitude sickness, also called acute mountain sickness, occurs when the body does not adjust properly to high altitudes with lower oxygen levels. Common symptoms include headache, dizziness, nausea, tiredness, shortness of breath, and difficulty sleeping.
The risk increases when climbing or traveling to high altitudes too quickly. One of the most effective ways to prevent altitude sickness is the use of acetazolamide, a medication that helps the body adapt to altitude faster and can reduce the severity of symptoms.
It is often recommended for people traveling to high mountains or those with a history of altitude sickness. Drinking enough fluids, resting, and ascending gradually can also help reduce the risk.
