I have Hashimoto’s. I was diagnosed before my thyroid hormones were technically low — fatigue and a changing physique were the initial signals that prompted testing. When the diagnosis came, I thought it would lead to a solution. It led to “watch and wait.”
Watch and wait in Hashimoto’s means: monitor labs annually, wait until the thyroid is sufficiently damaged to stop producing hormone, then replace that hormone pharmacologically and increase the dose as the gland progressively fails. That was the plan.
I was too stubborn and too committed to understanding the actual physiology to accept that.
What Hashimoto’s Actually Is
Hashimoto’s is not a thyroid problem. It is an immune problem that attacks the thyroid. The formula for developing it requires: a genetic predisposition (the autoimmune gene), a leaky gut (which allows undigested proteins into the bloodstream, triggering the immune response), and often a triggering infection or significant stress event.
Treating it as a thyroid problem — with only thyroid hormone replacement — addresses the consequence while leaving the cause entirely untouched. The immune attack continues. The thyroid continues to be damaged. The hormone dose continues to climb.
The Root-Cause Approach
Step 1: The gut
Healing and sealing the gut is the most foundational intervention in Hashimoto’s management. The 5R protocol of functional medicine — Remove (inflammatory foods, infections), Replace
(digestive enzymes, stomach acid), Reinoculate (probiotics, prebiotics), Repair (gut lining), and Rebalance (stress, sleep, lifestyle) — addresses the structural issue that allowed the immune cascade to begin.
Anti-inflammatory diet (at minimum removing gluten and dairy for an initial period) consistently reduces thyroid antibody levels. This is not coincidence — it is the removal of the molecular trigger that drives the cross-reactive immune response in many Hashimoto’s cases.
Step 2: The adrenals
The HPA axis and the thyroid are intimately connected. Chronic cortisol elevation suppresses thyroid conversion, reduces TSH (masking the picture), and maintains the inflammatory state that drives autoimmune activity. Adrenal support and stress regulation are not optional adjuncts in Hashimoto’s — they are central to the protocol.
Step 3: Targeted thyroid nutritional support
Selenium is one of the most evidence-supported interventions in Hashimoto’s — it reduces thyroid antibody levels and supports T4 to T3 conversion. Iodine requires careful attention: it is necessary for thyroid function but can worsen Hashimoto’s at high doses, particularly in the early stages of healing. Tyrosine, zinc, and iron are also essential for thyroid hormone synthesis.
The Perimenopause Intersection
Hashimoto’s and perimenopause frequently overlap — and their symptoms are deeply entangled. Fatigue, weight gain, brain fog, mood changes, and cold intolerance can be Hashimoto’s, perimenopause, or both simultaneously. Standard bloodwork often misses the Hashimoto’s picture entirely (checking only TSH, not antibodies or conversion markers), leaving women with two unaddressed conditions presenting as one confusing symptom cluster.
A full thyroid panel — TSH, free T3, free T4, reverse T3, and TPO antibodies — alongside the full perimenopause hormonal assessment is essential for clarity. You cannot treat what you haven’t properly measured.
