The gut-brain axis
The gut-brain axis shows how closely our digestive system is connected with our mental life. This article looks at how disturbances in the gut, such as a disrupted microbiome or leaky gut syndrome, can influence our mental health, and which alternative therapeutic approaches can help with irritable bowel syndrome (IBS).
The gut-brain axis: how our gut influences the mind
The gut-brain axis is a fascinating and increasingly well-researched subject that shows how closely our digestive system is connected with our mental health. This complex network of nerve cells, hormones and immune mechanisms allows bidirectional communication between our gut and our brain. In this article we look at the most important aspects of this connection and show how alternative therapeutic approaches in irritable bowel syndrome (IBS) can play an important role in the treatment of both physical and psychological complaints.

What is the gut-brain axis
The gut-brain axis describes the bidirectional communication between our digestive system and the central nervous system. The gut, often called the “second brain”, is equipped with millions of nerve cells that communicate continuously with the brain. This connection runs through various channels, among them the enteric nervous system, hormones and immune cells. Changes in the gut, such as a disrupted microbiome or leaky gut syndrome, can have a direct effect on our mental state, and vice versa.
The role of the microbiome
A healthy microbiome, that is the entirety of the microorganisms in the gut, plays a central role in the gut-brain axis. It produces neurotransmitters such as serotonin, which is known as the “happiness hormone”, and in this way influences our mood and our well-being. If the microbiome is disrupted, as is often the case in people with IBS, this balance can start to falter. That can lead to a variety of psychological symptoms, including anxiety and depression.
Leaky gut syndrome and its effects on the brain
Leaky gut syndrome, in which the intestinal barrier becomes permeable, can have far-reaching effects on the gut-brain axis. Because of the increased permeability of the intestinal mucosa, toxic substances can enter the bloodstream, which can lead not only to inflammation but also to neuroinflammatory processes in the brain. These inflammatory processes are suspected of playing a role in the development of mental illness, particularly in illnesses that go hand in hand with chronic digestive complaints.
Conclusion
The gut-brain axis is a key factor for our well-being and shows how closely our digestive system and our mental life are connected with each other. Disturbances in the gut, such as a disrupted microbiome or leaky gut syndrome, can cause or intensify psychological complaints.
