Gut-Brain Axis

A healthy gut and balanced microbiome support normal movement between parasympathetic and sympathetic states. DGL protects the gut lining without raising blood pressure, unlike standard licorice which contains glycyrrhizin. Irritable bowel syndrome was historically misclassified as psychosomatic; the gut condition precedes and causes the mental state, not the reverse. A 2024 Nature study identified the neural pathway by which gut immune signals travel via vagal afferents to the brainstem and hypothalamus. A child's severe violent behavior resolved rapidly after treatment for gut pathogen and fungal overgrowth detected on stool and urine organic acid testing. Concussion is framed as a two-way vulnerability between brain injury and gut integrity. The gut-brain axis is a bidirectional relationship between the gut and the brain. The gut-brain axis is a bidirectional communication network between the gut and the brain. Gut activity can influence the brain, and brain activity can influence the gut. The vagus nerve and bloodstream are the two main routes for gut-to-brain signaling. The gut-brain axis is a bidirectional communication network linking the gut and brain. The gut-brain axis i…
