Why a normal TSH isn't the same as a healthy thyroid
Most Hashimoto's patients get diagnosed years after the autoimmune attack started — because TSH is the last marker to move. By then antibodies (TPO, TG) are elevated, free T3 conversion is dropping, and reverse T3 is climbing.
The thyroid is the symptom site. The driver is upstream.
The 5 root-cause categories we screen for
- Gut barrier breakdown — molecular mimicry between gluten and thyroid tissue.
- Chronic infection — EBV, H. pylori, Yersinia, Blastocystis.
- Heavy-metal load — mercury (dental), aluminum, halides (fluoride, bromide) blocking iodine receptors.
- Nutrient depletion — selenium, zinc, iron, vitamin D, B12.
- HPA-axis collapse — chronic stress suppresses T4→T3 conversion via cortisol pathways.
