The gut-brain connection isnt just some made up thing.
It’s a two-way communication highway, called the vagus nerve, that runs between your gut and your brain. And it carries more traffic than most people understand.
90% of serotonin is produced in the gut. The gut’s enteric nervous system contains roughly 500 million neurons (the most in our entire body). And the signals running up that vagus nerve from gut to brain are influencing your mood, your anxiety, your stress response, and your nervous system regulation - before your brain has a chance to get involved.
In perimenopause, when estrogen starts its decline, your gut barrier integrity becomes disrupted as well as your nervous system regulation. This connection with estrogen becomes the conversation that changes everything.
Comment GUT if you’ve never heard it explained this way.
