Gut microbiome may shape how strongly you react to stress

The community of microorganisms living in the digestive tract may influence how strongly the body and brain mobilise under pressure. Importantly, a stronger stress response does not necessarily mean a person handles stress worse. Researchers stress that the microbiome is just one piece of a complex puzzle.
