Eje intestino-cerebro y su impacto en el estrés

Abstract

The current pace of life, throughout the world, is one of the fastest in the history of humanity, which leads to increased stress in the population. It is a fact demonstrated in numerous studies that a state of permanent or chronic stress has a significant impact on people's health and quality of life. Current studies suggest that stress has relevant effects on the composition of the intestinal microbiota. Some of these effects may be: alterations in intestinal motility, mucosal transport, intestinal barrier function and visceral perception. By virtue of the above, the objective of this research is to capture the generalities about the gut-brain and the relationship it has with stress. The research was carried out under a bibliographic documentary type methodology, under the review modality. From the review it can be deduced that, since the psychological factor plays a key role in intestinal diseases, it leads us to assume the impact that stress has on the microbiota. On the other hand, there is also available evidence suggesting that gut microbiota is related to brain connectivity and cognitive performance and that manipulation of the gut and microbiota could be a promising way to improve cognition and emotional well-being in stressful situations. stress. In conclusion, it can be stated that if a diverse, rich and balanced microbiota is associated with better emotional well-being in people, the opposite would be the case, that its imbalance is also related to stress. However, it is important to highlight that there is no conclusive evidence and that this is a very young topic, with a long way to go. At the moment, the many existing indications encourage to continue in the investigations.
