Symptoms of High Altitude Sickness:
Increased altitude can lead to various symptoms collectively known as high altitude sickness. These symptoms typically occur at elevations above 8,000 feet (about 2,400 meters) and can range from mild to severe.

1. Acute Mountain Sickness (AMS):
- Headache: A persistent headache is one of the most common symptoms of AMS.
- Fatigue: Feeling unusually tired or weak.
- Dizziness: Feeling lightheaded or dizzy.
- Nausea or vomiting: Upset stomach or vomiting.

2. High Altitude Pulmonary Edema (HAPE):
- Shortness of breath: Difficulty breathing, especially with exertion.
- Cough: Dry cough that may produce frothy or pink phlegm.
- Chest tightness: Feeling of pressure or tightness in the chest.
- Bluish skin: Lips, face, or nails may turn blue due to lack of oxygen.

3. High Altitude Cerebral Edema (HACE):
- Confusion: Disorientation, memory loss, or changes in behavior.
- Difficulty walking: Lack of coordination or balance.
- Severe headache: Intense headache that does not respond to pain medication.
- Loss of consciousness: Fainting or inability to stay awake.
It is important to recognize these symptoms and seek medical attention if they worsen or if severe symptoms develop. Prevention strategies include gradual acclimatization, staying hydrated, avoiding alcohol and tobacco, and descending to lower altitudes if symptoms persist. If left untreated, high altitude sickness can progress rapidly and lead to life-threatening complications.
