I have acid reflux and possibly a mild hiatal hernia. When it triggers in Just The Right Way, I also get severe panic attack symptoms.
When I started investigating it (my coping mechanism during panic attacks) I discovered that the vagus nerve travels next to the esophagus through the diaphragm.
So my complete layman explanation was that the stomach pushes through the diaphragm during a hiatal hernia -> it rubs against the vagus nerve -> panic attack symptoms.
I might need to add the study of vagus nerve to "why haven't we studied this about the human body more" -list along with gut bacteria composition.
