Episode notes
Gut Dysbiosis Drives Anxiety
- Anxiety is strongly linked to gut bacteria imbalances that drive inflammation and disrupt neurotransmitter production.
- This dysbiosis heightens stress responses and reduces beneficial bacteria like Fecalobacterium prausnitzi that regulate mood.
Leaky Gut Amplifies Anxiety
- Butyrate-producing bacteria maintain gut lining integrity, preventing leaky gut and systemic inflammation.
- Leaky gut allows toxins to reach the brain, causing neuroinflammation that worsens anxiety and emotional regulation.
Probiotics Calm Stress Response
- Beneficial strains like lactobacillus and bifidobacterium regulate the stress hormone cortisol by modulating the HPA axis.
- They boost GABA production, the brain's calming neurotransmitter, reducing anxiety loops.
