The Interplay Between Interoception and the Gut Microbiome and its Impact on Mental Health

The interplay between interoception and the gut microbiome significantly influences mental health outcomes, highlighting a complex relationship mediated by the gut-brain axis (GBA). Interoception, the process of sensing and interpreting internal bodily signals, plays a key role in maintaining homeostasis and adapting to internal and external changes. Dysfunction in interoception has been linked to anxiety, eating disorders, and psychosomatic conditions, with therapies like mindfulness and interoceptive exposure therapy (IET) demonstrating therapeutic promise. The GBA, a bidirectional communication network between the gut and brain, shapes mental health through neurotransmitter production, immune responses, and inflammation. Emerging research shows the impact of gut microbiota on neurotransmitter signaling and cognitive processes, influencing emotional regulation and stress management. Understanding the relationship between interoception, the GBA, and psychological therapies provides a foundation for advancing holistic approaches to mental health treatment and well-being. Future studies exploring these interconnected systems may reveal innovative strategies for addressing mental health disorders.
