Over 90–95% of serotonin and nearly half of the body’s dopamine are produced in the gut, not the brain, and that one fact explains why so many ADHD meltdowns seem to come out of nowhere. In this episode, Dana Kay breaks down how gut inflammation, immune activation, and nervous system overload can drive ADHD symptoms long before behavior ever appears.
This is Part 2 of a 5-part series unpacking the biological stressors behind ADHD. After decoding blood sugar dysregulation in the previous episode, Dana explains why the gut functions as a control panel for emotional regulation, focus, and impulse control and how the vagus nerve sends stress signals straight from the gut to the frontal lobe.
Parents will learn why many children show no digestive symptoms despite significant gut dysfunction, how altered gut bacteria affect neurotransmitters, and what questions to start asking when behavior doesn’t make sense. Dana also shares a powerful client story and introduces a practical tool designed to help parents stop guessing and start supporting the systems asking for help.
