Acclimatization is the process by which the body adjusts to changes in altitude, such as increased oxygen levels and lower atmospheric pressure.

Headache is the most common symptom of altitude sickness, occurring in up to 70% of individuals who ascend to high altitudes.

Swelling of the hands and feet is not a symptom of altitude sickness, but rather a symptom of high altitude pulmonary edema (HAPE), a more severe form of altitude sickness.

High altitude pulmonary edema (HAPE) is a severe form of altitude sickness characterized by the accumulation of fluid in the lungs.

High altitude cerebral edema (HACE) is a severe form of altitude sickness characterized by the accumulation of fluid in the brain.

The recommended rate of ascent to minimize the risk of altitude sickness is 1000 meters per day.

The recommended amount of time to spend at a given altitude before ascending further is 2 days.

Taking acetaminophen or ibuprofen is not a preventive measure to reduce the risk of altitude sickness.

The most effective treatment for altitude sickness is to descend to a lower altitude.

Chronic mountain sickness (CMS) is the chronic form of altitude sickness, characterized by persistent symptoms such as shortness of breath, fatigue, and headache.

Previous history of altitude sickness is a risk factor for altitude sickness.

Acute mountain sickness (AMS) is the rapid onset of altitude sickness, typically occurring within the first 24-48 hours of ascent to high altitude.

Diarrhea is not a symptom of acute mountain sickness (AMS).

The recommended treatment for acute mountain sickness (AMS) is to descend to a lower altitude.

Chronic mountain sickness (CMS) is the gradual onset of altitude sickness, typically occurring after several weeks or months of living at high altitude.
