Sequelae of returning from the plateau

Most of us now live in relatively low-lying areas, and even if we live in relatively high areas, it will not be higher than Gaoyuan. This is also why many people will experience severe altitude sickness when they go to the plateau for the first time, with problems such as nausea, vomiting, dizziness, and even fainting. Some people may still feel particularly uncomfortable and have strong aftereffects after leaving the plateau. So you have to pay more attention to your body after leaving the plateau.

Altitude sickness is a reaction that occurs before the body adapts to the low oxygen environment of the plateau. It usually only manifests as changes in physiological functions and rarely causes organic changes in organs. Acute altitude sickness is more likely to occur for people who quickly enter a plateau.

After a short rest and symptomatic treatment, the symptoms can gradually ease or disappear within 1-2 weeks. In very few people, acute altitude sickness symptoms last for more than three months and turn into chronic altitude sickness. Chronic altitude sickness is also functional and generally does not affect work and life. For those with severe reaction symptoms, the symptoms may disappear quickly after being moved to low-altitude areas or plains. Therefore, whether it is acute or chronic altitude sickness, there are generally no sequelae. Whether altitude sickness can leave sequelae requires specific analysis.

As long as high-altitude pulmonary edema is diagnosed and treated in time, there will be no sequelae, and most people can continue to work in the plateau after being cured. People with abnormal blood pressure at high altitudes will have their blood pressure return to normal without treatment after returning to the plains, and there will be no sequelae. Most diseases such as high-altitude heart disease, high-altitude polycythemia, and high-altitude coma can be cured without leaving any sequelae. However, although patients with severe high-altitude heart disease have recovered to varying degrees after being transferred to lowlands, the enlarged heart of some patients is not easy to recover; patients with high-altitude polycythemia who have hypertension, high-altitude heart disease, cerebral hemorrhage or cerebral thrombosis will have sequelae such as decreased heart function, decreased brain function, limb and language disorders; in some severe cases of high-altitude coma, due to severe damage to brain cells or cerebral hemorrhage, may have symptoms such as blurred vision and memory loss after recovery.
