A nerve based superhighway runs between the brain and the gut, taking information in both directions. Researchers suggest that chronic stress may play an important role in the development & recurrence of SIBO (Small Intestinal Bacterial Overgrowth), which can be an underlying cause of multiple food intolerance.
Gut bacteria (the microbiome) can contribute to stress by producing inflammatory Lipopolysaccharides which activate the amygdala - the brains stress center. Stress hormones like adrenaline and cortisol adversely affect the microbiome in many ways.

How does stress affect digestion?
- Stress reduces gastric acid production in the stomach. Stomach acid prevents bacteria from surviving in the stomach to enter the small intestine.
- Stress reduces gastrointestinal motility which can result in constipation
- Stress reduces secretory IgA – a protective immunoglobulin on the wall of intestinal membranes. This makes it possible for bacterial overgrowth to establish itself in the small intestine.
- Stress hormones cortisol and adrenalin appear to be associated with biofilm overgrowth in the intestines. Biofilm hides pathogenic bacteria & so protects it from elimination.
