Hashimoto’s — deeper dive into the root-cause layers
Did you know that 90–95% of hypothyroidism is autoimmune (Hashimoto’s)?
This means the immune system mistakenly attacks thyroid tissue. Medication has a role, but to truly heal we need to look at why this immune confusion is happening.
The truth: Hashimoto’s is rarely from a single cause — it’s usually overlapping “layers” that need peeling back.
Common Root Cause Layers
Immune dysregulation
Genetics, chronic stress, infections, toxins → immune confusion
Leads to TPO/Tg antibodies against thyroid tissue
Support with: vitamin D, selenium, zinc, stress reduction, immune-modulating herbs
Gut dysfunction
Leaky gut, SIBO, candida, dysbiosis → antigens cross gut wall → immune attack
Test with stool analysis, SIBO breath test
Support with: gut-healing nutrients (glutamine, zinc carnosine), targeted antimicrobials, probiotics
Nutrient deficiencies
Common: selenium, zinc, iron, vitamin D, B12, iodine (sometimes)
Deficiency = poor T4→T3 conversion, increased oxidative stress
Correct with diet + targeted supplements after testing
Hormonal imbalances
Oestrogen dominance, PCOS, low progesterone, adrenal dysregulation
Cortisol imbalance suppresses thyroid conversion
Address with blood sugar support, stress regulation, cycle support
Toxin exposure
Fluoride, plastics, pesticides, mould, heavy metals → disrupt thyroid enzymes & hormones
Reduce exposures (filtered water, clean products, mould testing if needed)
Support detox pathways with protein, cruciferous veggies, antioxidants
Nervous system dysregulation
Chronic stress/trauma → sympathetic dominance → reduced vagal tone
Leads to poor digestion + higher inflammation
Support with meditation, vagal-stimulating practices, calming herbs (lemon balm, chamomile)
Dietary stress
Under-eating, low-carb, fasting → cortisol spikes, low T3
Leads to fatigue, slowed metabolism, and hormone imbalances
Rebuild with regular, balanced meals rich in protein & wholefood carbs
