An untreated leaky gut can contribute to the development or intensification of autoimmune diseases. Due to the constant permeability of the intestinal wall, foreign substances enter the bloodstream, which leads to chronic inflammation and an overreaction of the immune system. In the long term, the immune system can lose the distinction between "foreign" and "own" - it begins to attack the body's own structures. This mechanism can be detected in many autoimmune diseases such as Hashimoto's, rheumatism or coeliac disease. A healthy, tight intestinal barrier is therefore essential to regulate the immune system and counteract autoimmune processes.

Yes, there is a close connection between leaky gut and psychological complaints. 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.
