The term „leaky gut“ is increasingly common both in scientific circles and among patients interested in gut health and the microbiome.
While the topic continues to be actively researched, a growing body of evidence suggests that the state of the intestinal barrier may matter not only for digestion, but also for the immune system, inflammation and overall health.
The intestines are not just for digestion. They are a complex protective system that controls what passes from the intestinal tract to the bloodstream.
A healthy intestinal barrier allows:
The cells of the intestinal mucosa are connected by the so-called. tight junctions - structures that act as „controlled gates“.
In a condition known as leaky gut, it is believed that the intestinal barrier becomes more permeable than normal.
This can allow:
pass more easily through the intestinal wall and activate the immune system.
Symptoms are often non-specific and can vary from person to person.
Most often discussed:
It is important to emphasize that these symptoms can also be seen in other conditions.
Several factors are associated with damage to the intestinal barrier:
Prolonged stress can negatively affect the microbiome and inflammatory processes.
A diet high in ultra-processed foods, sugar and low in fibre can upset the balance in the gut.
Frequent use of antibiotics can reduce the beneficial bacteria in the microbiome.
Some inflammatory diseases are associated with changes in the intestinal barrier.
The gut microbiome plays a key role in maintaining a healthy intestinal mucosa.
Beneficial bacteria produce substances such as butyrate, which:
In dysbiosis, this balance can be disturbed.
The topic of „leaky gut“ is still subject to scientific debate and there is no single standard diagnostic test.
The assessment usually includes:
The approach is individual, but often includes:
If you have:
it is better to consult a specialist.
Leaky gut is a topic that is attracting increasing attention in modern medicine. While science is still continuing to explore all the mechanisms behind this condition, it is clear that the gut barrier and microbiome play an important role in overall health.
Maintaining a healthy microbiome balance and good eating habits can be an important step towards better intestinal and general well-being.
