The Gut-Brain Axis in Psychosomatic Disorders: A Biological Exploration of Mind-Body Interactions

Psychosomatic disorders present a compelling challenge in modern medicine, where psychological stress manifests as physical symptoms without an identifiable organic cause. Recent advances in neuro gastroenterology and psychoneuroimmunology have illuminated the gut-brain axis (GBA) as a central communication network linking emotional, cognitive, and physical health. This paper explores the biological basis of the gut-brain axis, its role in psychosomatic manifestations, and the implications for diagnosis and integrative treatment strategies. A particular focus is given to the microbiota's role in mediating gut-brain communication, neuroinflammation, and autonomic regulation. Understanding this intricate interplay is crucial to developing multidisciplinary approaches to psychosomatic disorders such as irritable bowel syndrome (IBS), fibromyalgia, and somatic symptom disorder.
