What is not a sign of Acute Mountain Sickness?

Severe coughing is not a typical sign of Acute Mountain Sickness (AMS), making it the correct response to the question. AMS usually presents with symptoms related to the lack of oxygen at high altitudes, and the most recognized signs include headaches, dizziness, and loss of appetite.

Headaches occur due to decreased oxygen levels and increased intracranial pressure as the body struggles to acclimatize to higher altitudes. Dizziness can result from the body's response to altitude changes and decreased oxygen delivery to the brain. Loss of appetite is also common, as the body diverts its resources to cope with the environmental stress rather than focusing on digestion.

Severe coughing is not associated with AMS and may suggest other respiratory conditions, such as bronchitis or an infection. Therefore, it stands out as an incorrect symptom when considering the typical signs of Acute Mountain Sickness.
