61: Biology of Trauma: How Trauma Fuels Autoimmunity & Hashimoto’s – With Dr. Aimie Apigian

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews Dr. Aimie Apigian, physician and author of The Biology of Trauma. Together, they explore how unresolved trauma – often overlooked in thyroid care – can predispose the body to autoimmunity, create nervous system imbalances, and keep people stuck in chronic fatigue or thyroid symptoms despite “doing everything right.” Dr. Apigian shares her journey from biochemistry and foster parenting to becoming a leading trauma expert, as well as her own experience with autoimmunity. She explains how trauma physiology differs from stress, why unresolved attachment wounds fuel thyroid issues, and what tools can help rewire the nervous system for safety and healing. What you’ll learn in this episode: Trauma isn’t always what you think. Many people dismiss their experiences because they didn’t have “big T” trauma. Dr. Aimie explains how even subtle or forgotten childhood events can rewire the nervous system, making the body feel unsafe and setting the stage for autoimmunity. Autoimmunity can be a trauma response. The body’s immune system reflects what the nervous system has learned: “it’s not safe to be me.” This creates a biology of trauma that keeps us in fight, flight, or freeze, driving thyroid imbalances and chronic fatigue. Why stress management isn’t enough. Breathwork, meditation, or cold plunges may help stress, but if the body is in trauma physiology, those tools can backfire. Healing requires working within your body’s capacity and building a “window of tolerance” for safety. How attachment wounds can affect thyroid health. From not being held enough as a baby to learning to suppress needs in childhood, these early experiences train us to abandon ourselves. Dr. Aimie shares how these patterns directly connect to autoimmune conditions like Hashimoto’s. Signs you might have stored trauma. Feeling constantly unsafe, being stuck in cycles of overwhelm, having unexplained fatigue, or always waiting for the “next shoe to drop” are all red flags that your body may be carrying unresolved trauma. Tools that create a biology of safety. Somatic practices, EMDR, neurofeedback, and Dr. Aimie’s five somatic self-practices can shift the nervous system out of trauma and into safety – often in under five minutes – without needing to rely on substances or old coping strategies.
