Hook
You feel cold when nobody else is. Your hair is on the bathroom floor. Your TSH came back “normal.” You are not crazy. The test was incomplete.
What’s actually happening
Hashimoto’s pathophysiology: autoimmune attack on thyroid tissue, mediated by TPO and Tg antibodies, often present for years before TSH moves out of range. The reference range vs. functional range distinction. Why subclinical hypothyroidism is dismissed in primary care.
Why this is happening to you specifically
Risk factors: female sex, family autoimmune history, post-pregnancy or post-perimenopausal hormonal shift, gluten reactivity in a subset, environmental triggers. Why women in their 30s and 40s are the modal patient.
What you can do today
The lab panel to request:
- TSH (you already have this)
- Free T4
- Free T3
- Reverse T3
- TPO antibodies
- Thyroglobulin antibodies
- Ferritin (low ferritin masks thyroid symptoms)
How to ask for them. What to do if your doctor refuses. (Spoiler: there are direct-order options. Name them.)
What to stop doing
Accepting “your TSH is normal” as a complete answer. Self-diagnosing via Instagram. Buying T3 from sketchy online sources.
The supplement / product question
Selenium (200 mcg, evidence is moderate). Zinc. The gluten elimination question — what the actual literature says vs. what wellness influencers say. NDT vs. levothyroxine is a doctor conversation, not a blog conversation.
What we still don’t know
Whether early dietary intervention (in antibody-positive but TSH-normal patients) delays clinical hypothyroidism onset. Some evidence, no consensus.
