Why Gut Health Is Central to Everything
The human gut contains approximately 100 trillion microorganisms — collectively known as the microbiome — that influence immune regulation, nutrient absorption, hormone metabolism, neurotransmitter production, and inflammatory balance.
When the microbiome is disrupted (dysbiosis) or the intestinal barrier becomes permeable (“leaky gut”), the consequences extend far beyond digestive symptoms. Bacterial endotoxins (LPS) entering the bloodstream trigger systemic inflammation. Impaired nutrient absorption leads to subclinical deficiencies. Disrupted neurotransmitter production affects mood, sleep, and cognition. Immune dysregulation increases susceptibility to autoimmune conditions and chronic infections.
At St. George Hospital, we approach gut health as a critical component of treatment for virtually every condition we treat — from Lyme disease and CFS to cancer and longevity medicine.
