Abstract: The plateau is a typical extreme environment with low temperature, low oxygen and high
ultraviolet rays. The integrity of the intestinal barrier is the basis for the functioning of the intestine,
which plays an important role in absorbing nutrients, maintaining the balance of intestinal flora, and
blocking the invasion of toxins. Currently, there is increasing evidence that high altitude environment
can enhance intestinal permeability and disrupt intestinal barrier integrity. This article mainly focuses
on the regulation of the expression of HIF and tight junction proteins in the high altitude environment,
which promotes the release of pro-inflammatory factors, especially the imbalance of intestinal flora
caused by the high altitude environment. The mechanism of intestinal barrier damage and the drugs to
protect the intestinal barrier are reviewed. Studying the mechanism of intestinal barrier damage in high
altitude environment is not only conducive to understanding the mechanism of high altitude environment
affecting intestinal barrier function, but also provides a more scientific medicine treatment method
for intestinal damage caused by the special high altitude environment.
