I have all sorts of stomach issues and it’s come down to some sort of gastrointestinal functional disorder. I recall to all originally started after I first ever had an anxiety attack. Also when I get super nervous or stressed I start physically feeling unwell. I also can’t eat in a high emotional state without feeling nauseous.

The brain and the digestive system are connected directly via the vagus nerve. The connection is directly between the brain stem (where a lot of “fight or flight” signals happen) and many parts of the abdomen. There is a literal link between the reptilian part of our brain and most of our gut. While emotions generally involve lots of parts of the brain, the “oldest” emotions that involve fear, anxiety, etc. involve the brain stem.
