ABSTRACT
Hypoxia is one of the factors restricting the survival of people at high altitudes, which can cause various symptoms such as vomiting, diarrhea, palpitations, shortness of breath and acute coma. About 80% of patients with acute mountain sickness have at least one symptom of a gastrointestinal distress (e. g., anorexia, nausea, diarrhea, vomiting, etc.). The pathological characteristics, pathogenesis and drug treatment of intestinal injury caused by high-altitude hypoxia were studied, which is conducive to the diagnosis and treatment of plateau gastrointestinal diseases. Therefore, by summarized relevant literature and systematically expounds the related researches on intestinal damage caused by high altitude hypoxia. We summarized the changes of intestinal morphology, intestinal cells, intestinal flora and other intestinal homeostasis caused by high altitude hypoxia, the mechanism of intestinal inflammation and oxidative damage, and the treatment of traditional Chinese medicine, which provide reference and information for reference for scientific research workers and clinicians.
