The gut, that second brain: stress and digestion
Why a tense day is felt right down in the gut — and what you can concretely do about it.
The gut is sometimes called a “second brain.” The image is apt: the digestive system holds millions of neurons and constantly talks with the brain via the vagus nerve.
When stress goes to the gut
A stressful period alters gut motility, pain sensitivity and even the microbiome’s composition. As a result, the same meal can be perfectly digested on a calm day, and trigger discomfort on a tense one.
It’s not always the plate. Sometimes it’s the day around it.
Why context matters in the analysis
This is one reason Digelia reasons in trends and probabilities, never certainties. A food may seem problematic when the real factor was the week’s stress. The reliability score and observation period help untangle these situations.
Simple gestures
Eating calmly, chewing, walking after a meal: modest but real levers. Observing them over time gives them a chance to reveal their effect.
