What are the symptoms of High Altitude Sickness?
Verified Answer
What are the symptoms of High Altitude Sickness?
High altitude sickness, also known as acute mountain sickness (AMS), is a condition that can occur when people ascend to high altitudes too quickly. The symptoms of AMS can vary, but common symptoms include:
- Headache
- Nausea
- Vomiting
- Dizziness
- Fatigue
- Insomnia
- Shortness of breath
- Loss of appetite
In severe cases, AMS can progress to high altitude cerebral edema (HACE), which is a serious condition that can be life-threatening. Symptoms of HACE include severe headache, confusion, loss of coordination, and difficulty walking.

It is important to be aware of the symptoms of AMS and to descend to a lower altitude if they occur, as AMS can be treated effectively if it is caught in the early stages. If left untreated, AMS can become more severe and potentially fatal.

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):

It is important to recognize these symptoms and seek medical attention if they worsen or if severe symptoms develop.

If left untreated, high altitude sickness can progress rapidly and lead to life-threatening complications.
