We are learning more about this connection over time, but the underlying mechanisms are still being discovered.

You may have also heard of ‘leaky gut syndrome’ whereby the lifestyle factors such as stress, poor diet and physical inactivity are claimed to degenerate the lining of the digestive system, leading to partially digested food, toxin and bugs ‘leaking’ into the tissue beneath it.
