免疫系统认错了人, 把自家甲状腺当外敌, 一年年打成甲减。硒和碘是它的两个矿物——补对是帮手, 补过是帮凶; 麸质、十字花科的戒口大多被吓大了。药怎么吃、化验单怎么读, 这一岛讲明白。

Toulis 2010 meta: 200 µg/day × 6 months → anti-TPO ↓ ~30%. U-curve — don't megadose.

Iodine
Hashimoto thyroids are iodine-sensitive — too low or too high feeds autoimmune flares. Urinary iodine target 100-200 µg/L.
Endocrine
Hashimoto is autoimmune HPT — read it inside endocrine's thyroid axis to see levothyroxine timing + PPI/Fe interactions.
Depression & Anxiety
Hypothyroid mimic of depression: fatigue + anhedonia + weight gain + slowed cognition — every classic depressive feature can come directly from hypothyroidism. Checking TSH before treating depression is clinical bedrock; Hashimoto patients have 2-3× depression rate.
Hair Loss
Thyroid hormone sets the pace of follicle turnover. In hypothyroidism hair thins and the growth phase shortens, usually alongside fatigue and cold intolerance. This is the testable, reversible category — rule it out first.
Chronic Fatigue
Hypothyroidism is a standard stop on the fatigue work-up: found and corrected with levothyroxine, it belongs to the reversible layer rather than being filed as chronic fatigue.

什么是桥本 · 自身免疫攻甲状腺

Hashimoto's thyroiditis (HT) is one of the most common autoimmune diseases and the leading cause of hypothyroidism in developed countries:

Globally, 5–15% of women and 1–3% of men have positive anti-TPO / anti-Tg antibodiesPeak onset: women 30–60 years oldGenetic predisposition: a first-degree relative being positive raises risk roughly 5–10×
Core mechanism: the immune system mistakes thyroid peroxidase () and thyroglobulin (Tg) for foreign threats, producing anti-TPO + anti-Tg antibodies; T cells infiltrate thyroid tissue, driving chronic inflammation; thyroid cells are slowly destroyed; T4/T3 synthesis capacity drops; eventually rises and free T4 falls, producing hypothyroid symptoms.

Typical symptoms (often misattributed to 'aging' or 'depression'):

Persistent fatigue / sleepiness (even after 8–9 hours of sleep)Cold intolerance (you feel cold when others don't)Slow weight gain (diet and exercise unchanged)Dry skin / thinning hair / brittle nailsConstipationMenstrual irregularity (heavy flow / long cycles)Low mood / poor focus / brain fogSlow heart rate / low blood pressureMuscle aches / joint stiffness
Hashimoto ≠ hypothyroidism

Hashimoto is the cause (autoimmunity); hypothyroidism is the functional state (high TSH + low T4)Hashimoto can exist for years without hypothyroidism (subclinical, antibodies only), or eventually progress to lifelong hypothyroidismConversely, hypothyroidism isn't always Hashimoto — it can also be congenital, iodine deficiency, post-surgical, drug-induced, or pituitary
Why does it get its own atlas island?

This is the bridge between Atlas and the health report — the report engine's `hashimoto` rule and the 'strict gluten-free AIP for Hashimoto' debunking matrix both point here. It's also the most classic case of 'single nutrient ≠ single answer': Hashimoto simultaneously involves Se, I, D, Fe, gluten, and autoimmune modulation. 'What should I supplement for Hashimoto?' can't be answered by any single nutrient.
