The Gut Insiders 5 Ways to Protect Your Gut Microbiome From Chronic Stress
Mar 1, 2026
They unpack the brain-gut connection and how stress physically disrupts digestion. They outline how stress hormones and nervous system shifts change gut motility, barrier function, and microbiome composition. They present five practical strategies like regular meal timing, gratitude walks, sleep hygiene, diaphragmatic breathing, and avoiding alcohol and ultra-processed foods to protect gut health.

Episode notes
Stress Is A Physiological State Not An Emotion
- Stress is a physiological survival state triggered before conscious thought, activating fight-or-flight via the sympathetic nervous system.
- Dr. Will Bulsiewicz explains CRH, adrenaline, and cortisol shift the body into action and deprioritize digestion and recovery.
How Stress Physically Disrupts The Gut
- Stress hormones directly alter gut function by changing motility, secretions, oxygen levels, and loosening tight junctions.
- These changes increase gut permeability, activate mast cells, raise inflammation, and heighten pain sensitivity even without diet changes.
Chronic Stress Weakens Microbiome And Raises Inflammation
- Chronic stress reshapes the microbiome toward opportunistic pathogens and lowers diversity.
- Dr. Will links weakened microbiome and barrier breakdown to systemic inflammation via lipopolysaccharide translocation.
