Altitude sickness has three levels:
Acute mountain sickness. This is the most prevalent type of this sickness. It is also the mildest form, which only causes nausea, headache, dizziness, and muscle ache.
High-altitude pulmonary edema. This type can be life-threatening because fluids accumulate inside the lungs. Moreover, this type counts for most of the mortality-rate on this sickness.
High-altitude cerebral edema. This type is the most dangerous form because it occurs when fluid accumulates in the brain.
Several factors influence the severity of symptoms, including:
- An individual’s age, weight, blood pressure, and respiratory endurance
- How fast an individual climbs a high altitude
- The duration of time spent at that elevation
The following are some of the signs and symptoms of this sickness:
- Nausea, vomiting, or a loss of appetite
- Fatigue or weakness
- Tingling or prickling
- Feeling drowsy
Furthermore, altitude sickness can worsen over time, leading to significant problems, such as fluid in the lungs and brain enlargement. For such cases, seek medical help immediately.
