Thyroid Masterclass

Thyroid dysfunction is almost always treated the same way: check TSH, and if it’s high, prescribe thyroxine. But TSH alone rarely tells the whole story — and treating the number instead of the actual problem means many patients stay on hormone replacement for a gland that was never truly the issue.

This masterclass, part of the AIC Functional Medicine Training Program, teaches a practical framework for reading thyroid labs the way a functional medicine practitioner should: distinguishing true gland pathology (low T4, high TSH, no antibodies — a nutrient deficiency picture) from Hashimoto’s (elevated thyroid antibodies driving the pattern), from mitochondrial and insulin-resistance-driven “functional” hypothyroidism (low T3/T4 with normal-to-high insulin, where the gland is deliberately downregulating hormone output because metabolism is impaired), from stress-driven suppression, and from poor T4-to-T3 conversion caused by toxins or chronic infection. Dr. Ashwani Garg walks through each pattern with the corresponding root-cause approach, including when hormone therapy is genuinely warranted versus when it’s solving the wrong problem.

The session then builds out the root-cause protocol for Hashimoto’s and autoimmune thyroid conditions specifically — leaky gut, chronic infections and dysbiosis, molecular mimicry from genetically modified wheat/dairy/soy, and the impact of antibiotics, PPIs, painkillers, and steroids on gut and immune function — alongside the foundational levers of circadian light exposure, hydration and structured water, and a nutrient and antimicrobial protocol (iodine, tyrosine, selenium, zinc, B-complex, vitamin D, NAC/glutathione, rotating antimicrobial herbs, and probiotics). Age-adjusted TSH ranges and antibody thresholds are covered so practitioners can avoid both under- and over-treating.

The depth, terminology, and case-based teaching are calibrated for a practitioner audience, though informed patients who want a clinical-depth understanding of their own thyroid lab patterns are welcome to enroll.

A high TSH is a signal, not a diagnosis — and treating it as the whole story means missing cases where the real driver is a nutrient deficiency, chronic stress, an infection, or a mitochondria that’s deliberately downshifting metabolism.

This masterclass gives practitioners a lab-pattern framework for telling these apart, a root-cause protocol for Hashimoto’s and functional hypothyroidism, and clear guidance on when hormone therapy is genuinely needed versus when it’s solving the wrong problem, as part of the AIC Functional Medicine Training Program. Informed patients auditing this course will walk away with a clearer, evidence-grounded picture too — but the training is built, first, for the practitioner in the room.
