Yes, between leaky gut and psychological complaints is closely linked. The gut is often referred to as the “second brain” as it is connected to the central nervous system via the enteric nervous system. A disturbed intestinal barrier can have a significant impact on emotional balance. People with leaky gut often report inner restlessness, anxiety, depressive moods or the feeling of being constantly overstimulated. A leaky gut not only physically lets “foreign substances” into the system, but can also make it difficult to isolate oneself psychologically – which has a negative impact on the psyche in the long term.
