Your stomach does not operate alone.
Your brain, nervous system and digestive organs communicate constantly through the gut-brain connection.
The vagus nerve is one of the major communication pathways involved.
It helps carry the signals associated with slowing down, coordinating digestion and moving into a “rest-and-digest” state.
That may explain a familiar experience.
You eat a meal while relaxed on holiday and feel surprisingly comfortable.
You eat almost the same meal during a stressful working week and experience symptoms for hours.
The food may not have changed very much.
But the state your digestive system was operating in did.
This does not mean the symptoms are imaginary.
It means digestion responds to more than food and acid.
It also responds to the signals it receives.
