Episode notes
Gut As A Sensory Organ
- The gut is a sensory organ with its own nervous system, immune cells, and trillions of microbes that actively produce chemicals and signals.
- These microbes break down fiber, interact with immunity, and send readable signals to the brain via multiple pathways.
Three Highways From Gut To Brain
- Three main communication highways connect gut and brain: the immune system, the vagus nerve, and microbial metabolites.
- These pathways explain how gut barrier disruption and inflammation can influence mood, anxiety, fatigue, and brain fog.
Inflammation Links Gut To Mood
- Gut barrier disruption can make the immune system more reactive, raising systemic inflammation that affects the brain.
- Raised inflammation is linked to low mood, anxiety symptoms, fatigue, and brain fog, not as sole causes but as influential biological factors.
