🔥 What if a brain injury doesn't just affect your brain—but also your heart, gut, immune system, hormones, metabolism, and even the way your body heals? Read UnCurable (https://uncurablebook.com/) to explore how seemingly unrelated symptoms can be connected through the body's complex biological systems.
How a Brain Injury Can Affect Your Heart, Gut, Hormones, and Immune System
In this Made for Health minisode, Dr. Aaron Hartman continues his concussion series by explaining why a traumatic brain injury can have effects far beyond the brain itself. Using a "one brain, one body" perspective, he explores how the brain serves as the master regulator of nearly every system in the body. When that regulation is disrupted—whether by a concussion, emotional trauma, or PTSD-like events—it can contribute to problems involving the heart, digestive system, hormones, immune function, metabolism, and sleep.
Dr. Hartman discusses the connections between the brain and the vagus nerve, heart rate variability, the gut microbiome, neurotransmitter production, immune regulation, hormone balance, metabolic health, and lipid membranes. He explains how understanding these interconnected systems can help clinicians recognize why symptoms that seem unrelated may actually share a common neurological origin, setting the stage for the next episode focused on practical treatment strategies.
