Do hypertensive patients who travel on the Sichuan-Tibet Line really suffer from altitude sickness?

Altitude sickness, in a sense, is a kind of altitude sickness. It is a variety of uncomfortable symptoms caused by low-oxygen environments when people enter high-altitude environments above 3,000 meters. Known as altitude sickness, it is a common disease endemic to high-altitude areas. To put it bluntly, a person who lives in a low-altitude area and suddenly comes to a high-altitude area of ??more than 3,000 meters will experience a series of uncomfortable symptoms caused by altitude sickness, such as headaches, insomnia, anorexia, fatigue, and difficulty breathing.

Friends who come to Tibet for the first time will have symptoms of altitude sickness above 50%. As long as you have a good rest in Lhasa and other places, the symptoms will gradually disappear after 3 to 5 days of adaptation. This shows that altitude sickness is not something you will definitely get if you go to high-altitude areas, but you will get it if you go to high-altitude areas. As you adapt to the environment, altitude sickness will gradually disappear. In addition, the elderly, obese young people, and thin men and women have a high incidence of altitude sickness and have a high chance of occurrence.

Most areas on the most famous Sichuan-Tibet Line are at an altitude of 2,500-3,000 meters, so the probability of altitude sickness is high. Therefore, friends who have traveled along the Sichuan-Tibet Line know that there are two types of altitude sickness, acute altitude sickness and chronic altitude sickness. Acute altitude sickness will cause symptoms such as headache, dizziness, difficulty breathing, nausea and vomiting when you are not accustomed to high altitude areas. These symptoms usually resolve within a day or two and disappear after five days. The other type is chronic altitude sickness, which means that after living in high altitude areas for more than two or three months, symptoms such as headache, dizziness, difficulty breathing, nausea, and stomach reflux still persist. It is generally recommended to leave Tibet.

Altitude response refers to a series of natural physiological reactions that the human body produces after reaching a certain altitude to adapt to changes in air pressure, low oxygen levels, and dry air caused by altitude. Generally speaking, people with strong adaptability to the Sichuan-Tibet Line will disappear within two days, and people with poor adaptability will disappear within three days. In fact, many altitude sickness are caused by psychological effects. Many people rise from plateaus hoping to avoid or reduce them.
