Amie Hornaman

Dr. Amie Hornaman is a practitioner focusing on thyroid dysfunction and Hashimoto's disease. Her work addresses thyroid hormone regulation, including T3, T4, and reverse T3, alongside the impacts of stress, viral triggers, and lifestyle factors on thyroid health. She also discusses diagnostic lab testing and treatment approaches for thyroid disorders.

Low thyroid function is a causative factor in migraines and frozen shoulder.

"then I go into those wild and wacky symptoms that you wouldn't necessarily pair up with thyroid like migraines and frozen shoulder that absolutely can be attributed to low thyroid function." (said at 0:15:48)

While observational studies show a significant statistical association and comorbidity between hypothyroidism and migraine (e.g., in a large multinational cohort of over 33 million patients), the relationship is largely correlational and bidirectional rather than a definitive direct cause. Furthermore, evidence linking hypothyroidism directly to frozen shoulder (adhesive capsulitis) is mixed and unproven; a 2025 systematic review and meta-analysis of metabolic and hormonal factors found no significant association between frozen shoulder and thyroid function (SMD 0.067, 95% CI -0.024 to 0.158). Claiming that migraines and frozen shoulder can 'absolutely be attributed to low thyroid function' overstates correlational and conflicting observational findings as established causal relationships.

Impaired thyroid function reduces immune system function and diminishes the body's ability to surveillance and destroy cancer cells.

"So, we know that if your thyroid isn't functioning well, then your immune system isn't even functioning at a top level. So, why did we see, you know, so many people being taken out by COVID when, you know, it's just a virus. It's just a—man-made, but you know, that's a whole other discussion. But, you know what? If your thyroid isn't functioning well, even your ability to surveillance cancer cells, like your body's ability to seek out and destroy the cancer cells that we all have in our body" (said at 0:29:06)

While thyroid hormones do play a role in modulating cellular metabolism, leukocyte function, and adaptive immune responses (including T cell differentiation), the relationship between thyroid status and immune function is complex, bidirectional, and context-dependent rather than a simple on-off switch. Furthermore, asserting that impaired thyroid function impairs cancer immune surveillance across the board is an oversimplification not supported by clinical oncology data; in multiple malignancies, hypothyroidism is actually associated with slower tumor growth or improved responses to immune checkpoint inhibitor therapy, whereas thyroid hormones can sometimes stimulate tumor proliferation and angiogenesis.

Functional psychiatry uses T3 to treat conditions like manic depression and schizophrenia due to T3 receptor sites in the brain.

"Functional psychiatry will use T3 even for extreme cases, like manic-depressive and schizophrenia, they will use T3 because of the T3 receptor sites on the brain." (said at 0:32:13)

Triiodothyronine (T3 or liothyronine) augmentation has been studied and used in psychiatry for treatment-resistant affective disorders, including bipolar depression (historically referred to as manic depression), due to the role of thyroid hormones and thyroid hormone receptors in central nervous system neurotransmission and mood regulation. However, systematic reviews note that evidence for T3 in bipolar disorder remains limited, mixed, and based largely on small or open-label studies. Furthermore, there is no established clinical evidence or guideline support for using T3 to treat schizophrenia.

Epstein-Barr virus is a major precursor to Hashimoto's thyroiditis.

"EBV is a huge precursor to Hashimoto's." (said at 0:33:40)

While Epstein-Barr virus (EBV) has been investigated as a potential environmental trigger or cofactor in Hashimoto's thyroiditis and other autoimmune thyroid diseases, describing it as a "huge precursor" significantly overstates the scientific evidence. Observational studies report variable detection rates of EBV in thyroid tissue and blood of Hashimoto's patients, but findings are inconsistent, and controlled studies show no clear causal link or significant difference in viral presence compared to controls. Current consensus views EBV as one of several hypothetical environmental triggers in genetically predisposed individuals, rather than an established major precursor.

Eating gluten triggers molecular mimicry and antibody attacks against the thyroid gland in individuals with Hashimoto's thyroiditis.

"like you said, molecular mimicry, whenever you eat gluten, that's kicking up a thyroid storm. It's kicking up your antibodies basically to attack your thyroid." (said at 0:40:22)

The claim that eating gluten directly triggers acute antibody attacks or a "thyroid storm" via molecular mimicry in patients with Hashimoto's thyroiditis is overstated. While molecular mimicry (such as cross-reactivity involving transglutaminase enzymes) is a hypothesized theoretical link between celiac disease and autoimmune thyroiditis, published clinical studies do not demonstrate that gluten ingestion triggers acute antithyroid antibody surges or thyroid destruction in Hashimoto's patients who do not have celiac disease. Reviews of the scientific literature conclude that evidence is insufficient to recommend a gluten-free diet to non-celiac patients with Hashimoto's thyroiditis. Furthermore, a "thyroid storm" is a specific, life-threatening medical emergency involving severe hyperthyroidism, not a reaction triggered by gluten in Hashimoto's thyroiditis.
