Altitude sickness, also known as altitude sickness and mountain sickness, is strictly a classification of altitude sickness. It is a kind of discomfort caused by the rapid entry of human body into the plateau above 3000 meters above sea level and exposure to low-pressure and low-oxygen environment, and it is a common disease unique to plateau areas.

Common symptoms include headache, insomnia, loss of appetite, fatigue and dyspnea. Headache is the most common symptom, which is often forehead and temple pain, and the pain is aggravated when getting up at night or in the morning. Increasing lung ventilation, such as mouth breathing and mild activity, can relieve headaches. Altitude sickness can be divided into acute and chronic according to the acute and slow onset, and then clinically classified according to the organ system damaged by hypoxia.
