Levothyroxine replaces the thyroid hormone output that Hashimoto's is destroying. It doesn't address the autoimmune process destroying the tissue. Gärtner's randomized trial showed that selenium 200 mcg daily reduced TPO antibody titers by 40% in autoimmune thyroiditis patients. That's disease modification — slowing the immune attack on the thyroid — not just replacement. The gut-thyroid connection matters too: intestinal permeability allows undigested gliadin to enter the bloodstream, where molecular mimicry with thyroid tissue drives autoimmune cross-reactivity. Strict gluten elimination reduces antibody levels in genetically susceptible patients. I treat the autoimmune driver, not just the thyroid output.
How Thyroid Disorder Treatment Works
Thyroid disorder treatment begins with comprehensive thyroid testing (full panel including antibodies). For Hashimoto's, Dr. Hendry addresses the autoimmune drivers: gluten sensitivity (molecular mimicry with thyroid protein), gut dysbiosis (leaky gut and immune dysregulation), vitamin D deficiency (critical for autoimmune regulation), and selenium deficiency (reduces TPO antibodies). Acupuncture provides immune regulation, HPA axis normalization, and Chinese medicine constitutional support for the Kidney Yang Deficiency pattern of hypothyroidism.

Full Thyroid Axis Evaluation vs. TSH-Only Monitoring and Levothyroxine Monotherapy
Levothyroxine is the most prescribed medication in the United States, and it is an effective intervention for patients who convert T4 to T3 efficiently. The clinical problem is that T4-to-T3 conversion depends on selenoenzyme deiodinases, whose activity is impaired by selenium deficiency, elevated reverse T3, chronic stress-driven cortisol elevation, and caloric restriction, all common conditions in the patient population most likely to develop hypothyroidism. A 44-year-old woman has been on levothyroxine 100 mcg for five years. Her TSH has been maintained at 1.8 mIU/L, yet she reports persistent fatigue, cold intolerance, hair loss, and a 15-pound weight gain since starting medication. Her physician's response has been to confirm that her TSH is optimal. Free T3 testing reveals a value of 2.3 pg/mL; reverse T3 is elevated at 28 ng/dL, creating a reverse T3-to-free T3 ratio indicating significant receptor blockade. TPO antibodies are 480 IU/mL, indicating active Hashimoto's autoimmunity that levothyroxine does not address. Our protocol adds selenium 200 mcg, removes identified food triggers from her IgG panel, repletes vitamin D, and works with her physician to evaluate the clinical case for adding liothyronine (T3) based on the conversion impairment documented. Managing the full thyroid axis, not just the output signal of TSH, is what restores clinical function.
Research & Evidence
Thyroid physiology extends well beyond TSH, yet most thyroid monitoring in primary care relies on TSH as a sole indicator of thyroid status. Hoermann et al. (Eur Thyroid J. 2019) demonstrated through large-scale population data that TSH and free T3 are not linearly correlated at an individual level; patients with TSH within the reference range frequently show free T3 values in the lower quartile where hypothyroid symptoms consistently emerge. Reverse T3, the metabolically inactive isomer produced under cortisol excess and caloric restriction, competitively occupies T3 receptors without activating them, creating cellular hypothyroidism despite adequate T4 levels. Gartner et al. (J Clin Endocrinol Metab. 2002) demonstrated in a randomized trial that selenium supplementation at 200 mcg daily reduced TPO antibody concentrations by 40% in patients with autoimmune thyroiditis, establishing a correctable nutritional driver of Hashimoto's progression. Liontiris and Mazokopakis (Hell J Nucl Med. 2017) reviewed evidence linking iodine excess, gluten exposure, and vitamin D deficiency to Hashimoto's autoimmune activity, all modifiable factors that conventional TSH monitoring does not evaluate. Our thyroid protocol assesses TSH, free T3, free T4, reverse T3, TPO antibodies, thyroglobulin antibodies, selenium, vitamin D, and ferritin before determining intervention.
Your First Appointment
Bring all prior thyroid labs and current thyroid medications. Describe your full symptom picture — not just thyroid-specific symptoms. Associated gut, skin, joint, and mood symptoms are often part of the Hashimoto's autoimmune picture.
Why Dr. Hendry for Thyroid Disorder Treatment
Dr. Hendry's functional medicine and autoimmune expertise allows him to address Hashimoto's as an immune system problem with thyroid consequences — not simply a thyroid gland problem to be replaced with medication.
