Guest: Dr. Jessica Petros
Release Date: July 29, 2025
In Episode 546 of The Thyroid Fixer, host Dr. Amie Hornaman welcomes Dr. Jessica Petros, a renowned functional medicine expert specializing in chronic illness and root cause medicine. The episode delves into the intricate relationships between mold, Lyme disease, electromagnetic fields (EMFs), and thyroid health, offering listeners comprehensive insights and actionable strategies to combat thyroid dysfunction.
Introduction to Thyroid Health Challenges
Dr. Amie Hornaman sets the stage by emphasizing the complexities surrounding thyroid health, particularly for those battling hypothyroidism and related hormonal imbalances. She highlights the importance of understanding environmental and physiological factors that contribute to thyroid dysfunction beyond conventional diagnoses.
Mold Exposure and Thyroid Dysfunction
Timestamp: [19:18] – [23:17]
Dr. Jessica Petros begins by explaining how mold exposure directly impacts thyroid health. She cites a 2017 study published in Frontiers in Immunology titled "Non-Thyroidal Illness Syndrome in Patients Exposed to Indoor Air Dampness Microbiota Treated Successfully with T3," which demonstrates that individuals exposed to mold in water-damaged buildings exhibited thyroid-like symptoms that responded positively to T3 treatment.
Notable Quote:
Dr. Jessica Petros: “Mold really lowers immune systems. It causes cytokine storm in the brain... the thyroid is a sensitive gland and is affected.” ([22:24])
Dr. Petros explains that mold exposure can trigger inflammation, leading to disrupted communication between the brain and the thyroid gland. This inflammatory response can manifest as thyroiditis or hypothyroidism, especially in individuals with genetic predispositions to sensitivity, referred to as the "canaries in the coal mine."
Lyme Disease: A Hidden Threat to Thyroid Health
Timestamp: [32:25] – [37:58]
Transitioning to Lyme disease, Dr. Petros discusses its role in thyroid dysfunction. Lyme disease, caused by the Borrelia bacteria, is notorious for its ability to mimic other illnesses, earning it the title "the great mimicker." Petros explains that Lyme can induce molecular mimicry, where bacterial proteins resemble thyroid proteins, leading the immune system to mistakenly attack the thyroid gland.
Notable Quote:
Dr. Jessica Petros: “The Borrelia bacteria has some proteins that may be capable of triggering autoimmunity... the body starts to turn on the glands because the proteins are similar.” ([33:11])
She emphasizes the inadequacy of conventional testing methods like ELISA and Western blot for accurately diagnosing Lyme disease, advocating for more comprehensive functional medicine tests such as Vibrance’s Tick Port 1.0 and 2.0, which offer broader detection capabilities.
Electromagnetic Fields (EMFs) and Thyroid Health
Timestamp: [37:58] – [44:40]
Dr. Petros shifts focus to EMFs, discussing their emerging impact on thyroid function. She references a study from the Journal of Molecular Science in 2022, which investigated the effects of 4G EMFs on thyroid hormone dysfunction and observed significant alterations in the hypothalamic-pituitary-thyroid axis in male mice.
Notable Quote:
Dr. Jessica Petros: “There's a study published last year... it altered the hypothalamic expression of these genes.” ([43:28])
She notes the challenges in public awareness and the slow dissemination of scientific findings, urging listeners to stay informed and implement practical measures such as hardwiring devices, using EMF shields like Defender Shields, and minimizing wireless device usage to mitigate exposure.
Nervous System Dysregulation: The Root Cause
Timestamp: [12:42] – [50:53]
A central theme of the discussion is the role of the nervous system in mediating the body’s response to environmental stressors. Dr. Petros describes how chronic stress and trauma can lead to sympathetic nervous system dominance (fight or flight), resulting in mineral depletion critical for thyroid hormone production.
Notable Quote:
Dr. Jessica Petros: “Nervous system dysregulation or sympathetic overdrive... your free T3 might be stopping you from pooping.” ([15:15])
She advocates for holistic approaches to restore nervous system balance, including breathing exercises, vagal nerve stimulation (e.g., the Pulsetto device), adequate mineral intake, and stress-reduction techniques like dancing and spending time in nature.
Testing and Remediation Strategies
Timestamp: [24:32] – [36:30]
Dr. Petros outlines comprehensive testing protocols for identifying mold and Lyme disease. She recommends the Vibrance Total Tox Test for evaluating mycotoxins, heavy metals, and other environmental toxins. For Lyme disease, she prefers Vibrance’s Tick Port tests over conventional methods due to their higher accuracy rates.
For remediation, Petros advises on practical steps such as:
-
Mold: Conducting ERMI tests to assess home contamination levels and undertaking professional remediation if necessary. She emphasizes the difficulty in convincing non-affected household members to participate in remediation efforts.
-
Lyme Disease: Pursuing thorough diagnostic testing and individualized treatment plans to address co-infections and persistent symptoms.
Practical Steps and Recommendations
Timestamp: [44:11] – [51:08]
To empower listeners, Dr. Petros provides actionable strategies to support thyroid health amidst environmental challenges:
-
Minimize EMF Exposure:
- Use wired connections over wireless.
- Implement EMF shielding products.
- Limit the use of wireless devices, especially at night.
-
Enhance Detoxification Pathways:
- Ensure regular bowel movements to eliminate toxins.
- Support liver and kidney functions with appropriate nutrients and hydration.
- Utilize binders and sweating techniques (e.g., saunas) to excrete toxins.
-
Nutrient Support:
- Supplement with essential minerals like selenium, iodine, magnesium, and chromium.
- Incorporate antioxidants and bioflavonoids to combat oxidative stress.
-
Stress Management:
- Practice mindfulness, meditation, and breathing exercises.
- Engage in physical activities that promote relaxation and endorphin release.
Notable Quote:
Dr. Jessica Petros: “Getting into your body, getting out of your mind, learning an exercise, a dance, learning how to feel like a child again. This is the way to regain your sovereignty of your body and your mind.” ([50:02])
Conclusion and Final Thoughts
In wrapping up, Dr. Hornaman and Dr. Petros reiterate the interconnectedness of environmental exposures, nervous system health, and thyroid function. They emphasize the importance of a proactive, informed approach to thyroid health, leveraging both functional medicine insights and practical lifestyle adjustments.
Closing Quote:
Dr. Jessica Petros: “Regulating your nervous system, living as nature would intend... it's not okay if they're reacting to EMF like that, our bodies are also. They're teaching us.” ([41:16])
Dr. Petros directs listeners to her various platforms for further information and personalized care, underscoring the commitment to guiding individuals toward optimal thyroid health despite environmental challenges.
