The gut brain axis: Why one fashionable phrase cannot explain the mechanism

The gut brain axis involves the digestive system, nervous system, hormones, microbial metabolites and immune responses.

The gut brain axis describes communication between the digestive system and the nervous system. Hormones, microbial metabolites and immune responses also contribute to this picture.

A result belongs to a larger picture

The gut brain axis describes communication in several directions. The nervous, immune and endocrine systems, microbial metabolites and behaviours connected with sleep, stress and diet all take part. One fashionable phrase cannot identify which element matters most in a particular person.
