In Episode 51 of Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Lauren Noel, founder of Shine Natural Medicine, to explore the surprising overlap between ADHD and thyroid dysfunction. Together, they unpack how symptoms like brain fog, anxiety, fatigue, and mood swings often stem from deeper imbalances in the gut, immune system, nervous system, and environment.
Dr. Noel shares her functional medicine framework for uncovering the root causes behind ADHD and thyroid symptoms, from childhood trauma and gut dysbiosis to heavy metals, mold, and hormone imbalances. This episode is packed with clinical pearls and real-world healing stories that will inspire anyone who’s been told “it’s just in your head.”
What you’ll learn in this episode:
Thyroid dysfunction and ADHD share many symptoms, and may even be connected. Low thyroid function can mimic or worsen ADHD symptoms like brain fog, mood swings, and anxiety. Dr. Noel explains how even suboptimal thyroid labs can significantly affect cognition and emotional regulation. For many women, optimizing thyroid health leads to improvements in focus, motivation, and energy.
Childhood trauma and stress can lay the foundation for chronic health issues later in life. Emotional trauma and chronic stress can show up as brain fog, digestive issues, and mood instability decades later. Dr. Noel explains how early emotional wounds dysregulate the nervous system – and why therapies like EMDR and neurofeedback are crucial to true healing, not just symptom relief.
The gut-brain connection plays a key role in both ADHD and thyroid dysfunction. Chronic digestive issues, food sensitivities, and gut infections like H. pylori and SIBO can contribute to systemic inflammation that impacts the brain and thyroid. Dr. Noel walks through the testing she uses to identify gut imbalances and the protocols that support both digestive and mental wellness.
Heavy metals, mold, and environmental toxins are common in both thyroid and ADHD clients. Dr. Noel often sees exposure to mercury, lead, mold, and chemical sensitivities as hidden drivers behind fatigue, neurological symptoms, and thyroid resistance. She shares her process for identifying these toxic burdens and outlines how to detox safely through drainage and liver support.
Standard ADHD treatments often miss the mark for women. Stimulant medications might provide temporary focus, but they don’t resolve the deeper imbalances, and may even worsen anxiety or sleep issues. Dr. Noel discusses natural support strategies like amino acids, adaptogens, blood sugar balancing, and targeted nootropics to support long-term brain health.
A personalized approach can make all the difference. There’s no one-size-fits-all protocol for ADHD or thyroid issues. Dr. Noel emphasizes the power of testing (not guessing), building trust with your body, and making sustainable lifestyle changes such as eating for blood sugar balance, reducing histamine, and healing the limbic system, to support mood, memory, and metabolism.
