What’s the vagus nerve and how can I know it’s the cause of my issues?

The vagus nerve (CN-X) runs from the brain to the gut. It is responsible for your autonomic responses: digestion, bowel motility, lungs and heart. We don’t have a quick and easy test to assess if the vagus nerve is the cause of your issues.You might have long standing issues with digestion and bowel habits, you don’t gag easily and you may have mood/ mental health challenges.

Some good therapies that stimulate the vagus nerve include gargling water, singing loudly and performing coffee enemas consistently.
